  • Method Details

    • defaultGeorefGridStyle

      public B defaultGeorefGridStyle()
      Configures this builder with a default georef grid style.
      Returns:
      this builder.

    • body

      public B body()
      After calling this method, all subsequent interval(), styles(), customizableStyles(), … calls will apply to all grid lines. I.e. all grid levels.

      When no subsequent interval() or styles() call is done, a default interval and default styles are chosen. Note that the default interval might not be a good default. See interval for more information.

      For an example of how to use this method, see TLspGeorefGridStyle.

      Returns:
      this builder

    • body

      public B body(TLspGeorefGridStyle.GeorefLevel aGeorefLevel)
      After calling this method, all subsequent interval(), styles(), customizableStyles(), … calls will apply to all grid lines of the given level. E.g. to all 15 or 1 degree square lines.

      When no subsequent interval() or styles() call is done, a default interval and default styles are chosen. Note that the default interval might not be a good default. See interval for more information.

      For an example of how to use this method, see TLspGeorefGridStyle.

      Parameters:
      aGeorefLevel - the georef level
      Returns:
      this builder

    • label

      public B label()
      After calling this method, all subsequent interval(), styles(), customizableStyles(), … calls will apply to all grid labels. I.e. all grid levels.

      When no subsequent interval() or styles() call is done, a default interval and default styles are chosen. Note that the default interval might not be a good default. See interval for more information.

      For an example of how to use this method, see TLspGeorefGridStyle.

      Returns:
      this builder

    • label

      public B label(TLspGeorefGridStyle.GeorefLevel aGeorefLevel)
      After calling this method, all subsequent interval(), styles(), customizableStyles(), … calls will apply to all grid labels of the given level. E.g. to all 15 or 1 degree square labels.

      When no subsequent interval() or styles() call is done, a default interval and default styles are chosen. Note that the default interval might not be a good default. See interval for more information.

      For an example of how to use this method, see TLspGeorefGridStyle.

      Parameters:
      aGeorefLevel - the georef level
      Returns:
      this builder

    • overlay

      public B overlay()
      After calling this method, all subsequent interval(), styles(), customizableStyles(), … calls will only apply to all overlay labels. See also TLspGeorefGridOverlayLabelBuilder.

      When no subsequent interval() or styles() call is done, a default interval and default styles are chosen.

      For an example of how to use this method, see TLspGeorefGridStyle.

      Returns:
      this builder

    • interval

      public B interval(double aMin, double aMax)
      After calling this method, all subsequent styles(), customizableStyles(), … calls will only apply to the given scale interval. It is possible to define multiple scale intervals for every line or label level. In order to do this, the interval method (and its subsequent calls) can be called multiple times.

      When not calling this method after calling one of the body or label methods, an interval from 0 (completely zoomed out) to Double.MAX_VALUE (completely zoomed in) is used. So if you want to use the same styles for every scale, this method should not be called.

      Note that it is important to choose realistic scales for each level. Not doing so may cause the grid to switch to a less detailed level. For example when specifying an interval from 0 (completely zoomed out) to Double.MAX_VALUE (completely zoomed in) for the 1 minute square level, too much geometry would need to be generated when zoomed out. To prevent this, the grid layer may switch to a less detailed level. This problem should be prevented by choosing a higher minimum scale.

      When specifying overlapping intervals, it's not specified which styles will be used. It is advised to only specify non-overlapping intervals for the same (georef level/body or label) combination.

      For an example of how to use this method, see TLspGeorefGridStyle.

      Parameters:
      aMin - the minimum scale
      aMax - the maximum scale
      Returns:
      this builder

    • axes

      public B axes(EnumSet<TLspGeorefGridStyle.Axis> aAxes)

      This method specifies to which axes the subsequent calls, related to styling, are applied. It can be used to specify different styles, label formats, ... for each axis. This method only affects calls that are done after this method call.

      Examples:

      
   // For the X axis, the labels will be formatted and styled differently from the Y axis.
   TLspGeorefGridStyle.Builder builder = TLspGeorefGridStyle.newBuilder();
   builder.label(SQUARES_10000M).interval(interval);
   builder.axis(EnumSet.of(Axis.X)).styles(styles1).format(formatX);
   builder.axis(EnumSet.of(Axis.Y)).styles(styles2).format(formatY);
 
      
   // For the X axis, the labels will be formatted differently from the Y axis labels.
   // Both axes will use the same styles.
   TLspGeorefGridStyle.Builder builder = TLspGeorefGridStyle.newBuilder();
   builder.label(SQUARES_10000M).interval(interval);
   builder.styles(style1, style2);
   builder.axis(EnumSet.of(Axis.X)).format(formatX);
   builder.axis(EnumSet.of(Axis.Y)).format(formatY);
      Parameters:
      aAxes - the axes for which the subsequent calls are applied.
      Returns:
      this builder.

    • styles

      public B styles(Collection<ALspStyle> aStyles)
      This method specifies the styles to use for the current georef level/interval combination. Keep in mind that not all styles are supported (see TLspGeorefGridStyle for more information).

      For an example of how to use this method, see TLspGeorefGridStyle.

      Either this method or the customizableStyles method should be called at least once after calling one of the body, label or interval methods. Otherwise, default styling is used.

      The difference between the styles() and customizableStyles() method is that the latter accepts TLspCustomizableStyle instances which will be exposed through the ILspStyler which is set on the resulting layer. That styler will implement the ILspCustomizableStyler interface and expose those customizable styles. The styles passed in the styles() method will not be exposed. The benefit of the customizableStyles() method is that it is possible to customize the styles later on (for example through a user interface). If no customization is needed afterwards, the styles() method has the advantage to skip the overhead of creating TLspCustomizableStyle instances.

      Parameters:
      aStyles - the styles to use.
      Returns:
      this builder

    • styles

      public B styles(ALspStyle... aStyles)
      This method specifies the styles to use for the current georef level/interval combination. For more information, see styles(Collection).
      Parameters:
      aStyles - the styles to use
      Returns:
      this builder

    • customizableStyles

      public B customizableStyles(Collection<TLspCustomizableStyle> aStyles)
      This method specifies the customizable styles to use for the current georef level/interval combination. Keep in mind that not all styles are supported (see TLspGeorefGridStyle for more information).

      For an example of how to use this method, see TLspGeorefGridStyle.

      Either this method or the styles method should be called at least once after calling one of the body, label or interval methods. Otherwise, default styling is used.

    • customizableStyles

      public B customizableStyles(TLspCustomizableStyle... aStyles)
      This method specifies the customizable styles to use for the current georef level/interval combination. For more information, see customizableStyles(Collection).
      Parameters:
      aStyles - the styles to use
      Returns:
      this builder

    • format

      public B format(String aCoordinatePattern)

      This method specifies the format pattern to use for the labels of the current georef level/interval combination. This method has no effect for bodies.

      If this method is not called, a default format is used.

      The format in BNF notation (expressions enclosed in [] brackets are optional, expressions enclosed in {} brackets may be omitted or repeated): 

       <pattern>           ::= [<degrees15>] [<separator> <degrees>] [<minutes>]
 <degrees15>         ::= "D"
 <degrees>           ::= "d"
 <minutes>           ::= [<separator> <x> <separator> <y>]
 <x>                 ::= "X" <minutes_precision>
 <y>                 ::= "Y" <minutes_precision>
 <minutes_precision> ::= "0" | "1" | "2" | "3" | "4" | "5" | "6"
 <separator>         ::= { ? any character ? }
      When specifying the minutes precision, the value of 2 corresponds with a precision of 1 minute (can be represented by 2 digits, e.g. 37'). A value of 3 corresponds with a precision of 0.1 minute, etc... For example:
      • "GJ PJ 3716" has format "D d X2Y2"
      • "GJPJ3700016000" has format "DdX5Y5"

      Depending on the label, only some parts of the format string will be used. For example, when displaying line labels for minutes of sub-minute grid squares, only the X or Y part of the format string will be used.

      Parameters:
      aCoordinatePattern - the pattern used to format the label text
      Returns:
      this builder.

    • labelOrientation

      public B labelOrientation(TLspGeorefGridStyle.Orientation aOrientation)

      This method specifies the orientation to use for the labels of the current level/interval combination. This method will only work when it is called after one of the label() methods. The given format is only applied to grid labels with the spacing defined in a previous label call. It is also only used when the view scale lies within the scale interval defined in a previous interval call. This method has no effect for bodies.

      This method only has effect for labels that are painted along a line.

      If this method is not called, a default orientation is used, ALONG_LINE.

      Parameters:
      aOrientation - the orientation to use.
      Returns:
      this builder.

    • labelPosition

      public B labelPosition(TLspGeorefGridStyle.LabelPosition aLabelPosition)

      This method specifies the position of the line labels of the current spacing/interval combination with respect to the view. They can for example be placed at the left or at the right edge of the view, or both. For example, when a label is placed at the east or south side of a line, it will be placed at the left or lower edge of the view when using a rectangular projection like mercator.

      If this method is not called, a default label position is used, WEST_AND_SOUTH.

      Parameters:
      aLabelPosition - the label position to use.
      Returns:
      this builder
      Since:
      2017.0

      public B labelLinePosition(TLspGeorefGridStyle.LinePosition aLinePosition)

      This method specifies the position of the line labels of the current spacing/interval combination with respect to the line. They can for example be placed at the left or at the right of the line.

      If this method is not called, a default label position is used, ABOVE_OR_LEFT.

      Parameters:
      aLinePosition - the line position to use.
      Returns:
      this builder

      If this method is not called, a default offset is used, 3.0.

      Parameters:
      aGridOffset - the line offset to use.
      Returns:
      this builder

    • labelEdgeOffset

      public B labelEdgeOffset(double aEdgeOffset)
      This method specifies the offset of the label, away from the edge of the view. It is applied for the labels of the current georef level/interval combination. This method will only work when it is called after one of the label() methods. It will throw an exception otherwise.
