Method Detail

convertPositionToTargetContext

public static PositionCoordinate convertPositionToTargetContext(PositionCoordinate positionCoordinate,
                                                                ILayer targetLayer)

Convert the given PositionCoordinate to the given target ILayer.

Parameters:

positionCoordinate - The PositionCoordinate that should be converted.

targetLayer - The ILayer to which the PositionCoordinate should be converted to.

Returns:

The converted PositionCoordinate or null if a conversion is not possible.

convertPositionToTargetContext

public static PositionCoordinate convertPositionToTargetContext(PositionCoordinate positionCoordinate,
                                                                ILayer targetLayer,
                                                                boolean acceptNegativePosition)

Convert the given PositionCoordinate to the given target ILayer.

Parameters:

positionCoordinate - The PositionCoordinate that should be converted.

targetLayer - The ILayer to which the PositionCoordinate should be converted to.

acceptNegativePosition - true if a negative position value should be accepted, false if not.

Note: Accepting a negative position value could cause serious issues as a negative position typically means the position does not exist. Only in cases where the ViewportLayer and spanning is involved a negative position could make sense as the position could be for example not visible at the moment.

Returns:

The converted PositionCoordinate or null if a conversion is not possible.

Since:

1.6

convertColumnPositionToTargetContext

public static ColumnPositionCoordinate convertColumnPositionToTargetContext(ColumnPositionCoordinate columnPositionCoordinate,
                                                                            ILayer targetLayer)

Convert the given ColumnPositionCoordinate to the given target ILayer.

Parameters:

columnPositionCoordinate - The ColumnPositionCoordinate that should be converted.

targetLayer - The ILayer to which the ColumnPositionCoordinate should be converted to.

Returns:

The converted ColumnPositionCoordinate or null if a conversion is not possible.

convertColumnPositionToTargetContext

public static ColumnPositionCoordinate convertColumnPositionToTargetContext(ColumnPositionCoordinate columnPositionCoordinate,
                                                                            ILayer targetLayer,
                                                                            boolean acceptNegativePosition)

Convert the given ColumnPositionCoordinate to the given target ILayer.

Parameters:

columnPositionCoordinate - The ColumnPositionCoordinate that should be converted.

targetLayer - The ILayer to which the ColumnPositionCoordinate should be converted to.

acceptNegativePosition - true if a negative column position should be accepted, false if not.

Note: Accepting a negative position could cause serious issues as a negative position typically means the position does not exist. Only in cases where the ViewportLayer and spanning is involved a negative position could make sense as the position could be for example not visible at the moment.

Returns:

The converted ColumnPositionCoordinate or null if a conversion is not possible.

convertRowPositionToTargetContext

public static RowPositionCoordinate convertRowPositionToTargetContext(RowPositionCoordinate rowPositionCoordinate,
                                                                      ILayer targetLayer)

Convert the given RowPositionCoordinate to the given target ILayer.

Parameters:

rowPositionCoordinate - The RowPositionCoordinate that should be converted.

targetLayer - The ILayer to which the RowPositionCoordinate should be converted to.

Returns:

The converted RowPositionCoordinate or null if a conversion is not possible.

convertRowPositionToTargetContext

public static RowPositionCoordinate convertRowPositionToTargetContext(RowPositionCoordinate rowPositionCoordinate,
                                                                      ILayer targetLayer,
                                                                      boolean acceptNegativePosition)

Convert the given RowPositionCoordinate to the given target ILayer.

Parameters:

rowPositionCoordinate - The RowPositionCoordinate that should be converted.

targetLayer - The ILayer to which the RowPositionCoordinate should be converted to.

acceptNegativePosition - true if a negative row position should be accepted, false if not.

Note: Accepting a negative position could cause serious issues as a negative position typically means the position does not exist. Only in cases where the ViewportLayer and spanning is involved a negative position could make sense as the position could be for example not visible at the moment.

Returns:

The converted RowPositionCoordinate or null if a conversion is not possible.
