Constructor Detail

PackedCoordinateSequenceFactory

public PackedCoordinateSequenceFactory()

Creates a new PackedCoordinateSequenceFactory of type DOUBLE.

PackedCoordinateSequenceFactory

public PackedCoordinateSequenceFactory(int type)

Creates a new PackedCoordinateSequenceFactory of the given type. Acceptable type values are FLOATor DOUBLE

Method Detail

getType

public int getType()

Gets the type of packed coordinate sequence this factory builds, either FLOAT or DOUBLE

Returns:

the type of packed array built

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(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(CoordinateSequence)

create

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

Creates a packed coordinate sequence of type DOUBLE from the provided array using the given coordinate dimension and a measure count of 0.

Parameters:

packedCoordinates - the array containing coordinate values

dimension - the coordinate dimension

Returns:

a packed coordinate sequence of type DOUBLE

create

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

Creates a packed coordinate sequence of type DOUBLE from the provided array using the given coordinate dimension and measure count.

Parameters:

packedCoordinates - the array containing coordinate values

dimension - the coordinate dimension

measures - the coordinate measure count

Returns:

a packed coordinate sequence of type DOUBLE

create

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

Creates a packed coordinate sequence of type FLOAT from the provided array.

Parameters:

packedCoordinates - the array containing coordinate values

dimension - the coordinate dimension

Returns:

a packed coordinate sequence of type FLOAT

create

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

Creates a packed coordinate sequence of type FLOAT from the provided array.

Parameters:

packedCoordinates - the array containing coordinate values

dimension - the coordinate dimension

measures - the coordinate measure count

Returns:

a packed coordinate sequence of type FLOAT

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)

See Also:

CoordinateSequenceFactory.create(int, int)

create

public CoordinateSequence create(int size,
                                 int dimension,
                                 int measures)

Description copied from interface: CoordinateSequenceFactory

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

If the requested dimension or measures are 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)

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