Method Summary

Modifier and Type	Method	Description
CoordinateSequence	create(int size, int dimension)	Creates a CoordinateSequence of the specified size and dimension.
CoordinateSequence	create(Coordinate[] coordinates)	Returns an ExtendedCoordinateSequence based on the given array -- the array is used directly if it is an instance of ExtendedCoordinate[]; otherwise it is copied.
CoordinateSequence	create(CoordinateSequence coordSeq)	Creates a CoordinateSequence which is a copy of the given CoordinateSequence.
static ExtendedCoordinateSequenceFactory	instance()	Returns the singleton instance of ExtendedCoordinateSequenceFactory

Method Detail

instance

public static ExtendedCoordinateSequenceFactory instance()

Returns the singleton instance of ExtendedCoordinateSequenceFactory

create

public CoordinateSequence create(Coordinate[] coordinates)

Returns an ExtendedCoordinateSequence based on the given array -- the array is used directly if it is an instance of ExtendedCoordinate[]; otherwise it is copied.

Specified by:

create in interface CoordinateSequenceFactory

Parameters:

coordinates - the coordinates

create

public CoordinateSequence create(CoordinateSequence coordSeq)

Description copied from interface: CoordinateSequenceFactory

Creates a CoordinateSequence which is a copy of the given CoordinateSequence. This method must handle null arguments by creating an empty sequence.

Specified by:

create in interface CoordinateSequenceFactory

Parameters:

coordSeq - the coordinate sequence to copy

create

public CoordinateSequence create(int size,
                                 int dimension)

Description copied from interface: CoordinateSequenceFactory

Creates a CoordinateSequence of the specified size and dimension. For this to be useful, the CoordinateSequence implementation must be mutable.

If the requested dimension is larger than the CoordinateSequence implementation can provide, then a sequence of maximum possible dimension should be created. An error should not be thrown.

Specified by:

create in interface CoordinateSequenceFactory

Parameters:

size - the number of coordinates in the sequence

dimension - the dimension of the coordinates in the sequence (if user-specifiable, otherwise ignored)
