public class TLcdDGNCell
extends TLcdShapeList
implements ILcdDGNShape

This class represents a Cell from a DGN file. It extends a TLcdShapeList, in such a way that it becomes an ILcdDGNShape as well.

The cell has a name associated to it. This is the 6-character Radix-50 name for ordinary cells, or the 16-character name for shared cells.

The cell also has logical bit masks that reflect the classes and levels used by the cell's elements.

Constructor Details

TLcdDGNCell

public TLcdDGNCell(TLcdDGNDisplayInfo aDisplayInfo,
 String aName,
 int aClasses,
 long aLevels,
 ILcdShape[] aShapes)

Creates a new TLcdDGNCell with the given DGN properties, shape properties and shapes as specified for TLcdShapeList.

Parameters:

aDisplayInfo - the DGN display information.

aName - the cell name.

aClasses - the logical bit mask of classes used in the cell elements.

aLevels - the logical bit mask of levels used in the cell elements.

aShapes - the shapes associated with this cell.

TLcdDGNCell

public TLcdDGNCell(TLcdDGNDisplayInfo aDisplayInfo,
 String aName,
 int aClasses,
 long aLevels)

Creates a new TLcdDGNCell with the given DGN properties and shape properties as specified for TLcdShapeList.

Parameters:

aDisplayInfo - the DGN display information.

aName - the cell name.

aClasses - the logical bit mask of classes used in the cell elements.

aLevels - the logical bit mask of levels used in the cell elements.

Method Details

getName

public String getName()

Returns the cell name.

getClasses

public int getClasses()

Returns the logical bit mask of classes used in the cell elements.

getLevels

public long getLevels()

Returns the logical bit mask of levels used in the cell elements.

getDisplayInfo

public TLcdDGNDisplayInfo getDisplayInfo()

Description copied from interface: ILcdDGNShape

Returns the display information of this ILcdDGNShape.

Specified by:

getDisplayInfo in interface ILcdDGNShape

Returns:

the display information of this ILcdDGNShape.

getDGNType

public short getDGNType()

Description copied from interface: ILcdDGNShape

Returns the DGN type of this ILcdDGNShape.

Specified by:

getDGNType in interface ILcdDGNShape

Returns:

the DGN type of this ILcdDGNShape.

getValue

public Object getValue(TLcdDataProperty aProperty)

Description copied from interface: ILcdDataObject

Returns the value of the given property.

If the property is a collection, the returned value will never be null. If the property has not been set, an empty collection of the appropriate type will be returned (Set, List or Map).

The property must not be null, and must be declared in the data object's type or in one of its super types. Otherwise an IllegalArgumentException is thrown.

Specified by:

getValue in interface ILcdDataObject

Parameters:

aProperty - the property for which the value is to be returned

Returns:

the value of the given property for this data object

getDataType

public TLcdDataType getDataType()

Description copied from interface: ILcdDataObject

Returns the type of this data object. This can never be null.

Specified by:

getDataType in interface ILcdDataObject

Returns:

the type of this data object

setValue

public void setValue(TLcdDataProperty aProperty,
 Object aValue)

Description copied from interface: ILcdDataObject

Sets the value of the given property for this data object. The implementation is allowed to throw an exception if the given value can't be set.

The given property must be declared in the data object's type or in one of its super types. In other words, getDataType().getProperties().contains( aProperty ) should always be true. Otherwise, the implementation should throw an IllegalArgumentException.

Specified by:

setValue in interface ILcdDataObject

Parameters:

aProperty - the property for which the value is to be set

aValue - the value to set

See Also:

• TLcdDataType.getProperty(String)

getValue

public Object getValue(String aPropertyName)

Description copied from interface: ILcdDataObject

Convenience method that returns the value of the property with the given name.

If more than one property exists with the given name, the most specific property should be used (this is the property defined by the most specialized type in this object's data type hierarchy).

See ILcdDataObject.getValue(TLcdDataProperty) for more information.

Specified by:

getValue in interface ILcdDataObject

Parameters:

aPropertyName - the name of the property of which the value is to be returned

Returns:

the value of the property with the given name

See Also:

• TLcdDataType.getProperty(String)

setValue

public void setValue(String aPropertyName,
 Object aValue)

Description copied from interface: ILcdDataObject

Convenience method that sets the value of the property with the given name.

If more than one property exists with the given name, the most specific property should be used (this is the property defined by the most specialized type in this object's data type hierarchy).

See ILcdDataObject.setValue(TLcdDataProperty, Object) for more information.

Specified by:

setValue in interface ILcdDataObject

Parameters:

aPropertyName - the name of the property of which the value is to be set

aValue - the value to set

hasValue

public boolean hasValue(TLcdDataProperty aProperty)

Description copied from interface: ILcdDataObject

Indicates whether this data object has a value for the given property.

• aProperty is from the right data type, and this instance has a value for it: returns true
• aProperty is from the right data type, and this instance has no value for it: returns false
• aProperty is not from the right data type: not allowed, you will get IllegalArgumentException
• aProperty is null: not allowed, you will get NullPointerException

A multivalued property is considered to have a value if it has at least one value.

Specified by:

hasValue in interface ILcdDataObject

Parameters:

aProperty - the property for which to return whether a value is present or not.

Returns:

true if this data object has a value for the given property, false otherwise.

hasValue

public boolean hasValue(String aPropertyName)

Description copied from interface: ILcdDataObject

Indicates whether this data object has a value for the given property.
See ILcdDataObject.hasValue(TLcdDataProperty) for more information.

Specified by:

hasValue in interface ILcdDataObject

Parameters:

aPropertyName - the name of the property for which to return whether a value is present or not.

Returns:

true if this data object has a value for the property with the given name, false otherwise.
