Constructor Detail

PolylineChange

public PolylineChange()

Constructs an empty polyline change.

Method Detail

finalize

protected void finalize()

Overrides:

finalize in class Object

close

public void close()

Specified by:

close in interface AutoCloseable

getMovedPoints

@NotNull
public List<Long> getMovedPoints()

Returns the indices of the points in the new polyline that were moved in this change.

This only considers individual point moves, so if the whole polyline was translated, this method can still return false for individual points. For checking whether a translation took place, see getTranslation.

Returns:

the indices of the points in the new polyline that were moved in this change.

getRemovedPoints

@NotNull
public List<Long> getRemovedPoints()

Returns the indices of the points in the old polyline that were removed in this change.

Returns:

the indices of the points in the old polyline that were removed in this change.

getInsertedPoints

@NotNull
public List<Long> getInsertedPoints()

Returns the indices of the points in the new polyline that were inserted in this change.

Returns:

the indices of the points in the new polyline that were inserted in this change.

getTranslation

@Nullable
public Coordinate getTranslation()

Returns the translation that was applied on the polyline.

This is the result of use the method translate on the polyline. The value may be null if no translation happened.

Returns:

the translation that was applied on the polyline.

addMovedPoint

public void addMovedPoint(long movedPointIndex)

Adds the index of the point that is moved.

Parameters:

movedPointIndex - the index of the point in the new polyline that was moved in this change.

See Also:

getMovedPoints

addRemovedPoint

public void addRemovedPoint(long removedPointIndex)

Adds the index of the point that is removed.

Parameters:

removedPointIndex - the index of the point in the old polyline that was removed in this change.

See Also:

getRemovedPoints

addInsertedPoint

public void addInsertedPoint(long insertedPointIndex)

Adds the index of the point that is inserted.

Parameters:

insertedPointIndex - the index of the point in the new polyline that was inserted in this change.

See Also:

getInsertedPoints

setTranslation

public void setTranslation(@NotNull
                           Coordinate translation)

Sets the translation that was applied on the polyline.

Parameters:

translation - the translation that was applied on the polyline in this change.

See Also:

getTranslation

hasPointMoved

public boolean hasPointMoved(long index)

Returns true if the moved points of this change contain the given index.

Parameters:

index - the point index in the new polyline.

Returns:

true if the moved points of this change contain the given index.

hasPointRemoved

public boolean hasPointRemoved(long index)

Returns true if the removed points of this change contain the given index.

Parameters:

index - the point index in the old polyline.

Returns:

true if the removed points of this change contain the given index.

hasPointInserted

public boolean hasPointInserted(long index)

Returns true if the inserted points of this change contain the given index.

Parameters:

index - the point index in the new polyline.

Returns:

true if the inserted points of this change contain the given index.
