Constructor Details

PackedCoordinateSequenceFactory

public PackedCoordinateSequenceFactory()

Creates a new PackedCoordinateSequenceFactory of type DOUBLE.

PackedCoordinateSequenceFactory

public PackedCoordinateSequenceFactory(int type)

invalid reference

PackedCoordinateSequenceFactory#Float

or

invalid reference

PackedCoordinateSequenceFactory#Double

PackedCoordinateSequenceFactory

Returns the type of packed coordinate sequences this factory builds, either

invalid reference

PackedCoordinateSequenceFactory#Float

or

invalid reference

PackedCoordinateSequenceFactory#Double

setType

public void setType(int type)

Sets the type of packed coordinate sequences this factory builds, acceptable values are

invalid reference

PackedCoordinateSequenceFactory#Float

or

getDimension

public int getDimension()

setDimension

public void setDimension(int dimension)

create

public CoordinateSequence create(Coordinate[] coordinates)

Description copied from interface: CoordinateSequenceFactory

Returns a CoordinateSequence based on the given array. Whether the array is copied or simply referenced is implementation-dependent. This method must handle null arguments by creating an empty sequence.

Specified by:

create in interface CoordinateSequenceFactory

Parameters:

coordinates - the coordinates

See Also:

• CoordinateSequenceFactory.create(org.locationtech.jts.geom.Coordinate[])

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

See Also:

• CoordinateSequenceFactory.create(org.locationtech.jts.geom.CoordinateSequence)

create

public CoordinateSequence create(double[] packedCoordinates,
 int dimension)

See Also:

• invalid reference

  org.locationtech.jts.geom.CoordinateSequenceFactory#create(double[], int)

create

public CoordinateSequence create(float[] packedCoordinates,
 int dimension)

See Also:

• invalid reference

  org.locationtech.jts.geom.CoordinateSequenceFactory#create(float[], int)

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)

• CoordinateSequenceFactory.create(int, int)
