PackedCoordinateSequence class abstract

A {@link CoordinateSequence} implementation based on a packed arrays. In this implementation, {@link Coordinate}s returned by #toArray and #get are copies of the internal values. To change the actual values, use the provided setters.

For efficiency, created Coordinate arrays are cached using a soft reference. The cache is cleared each time the coordinate sequence contents are modified through a setter method.

Constructors

PackedCoordinateSequence(int dimension, int measures)
Creates an instance of this class @param dimension the total number of ordinates that make up a {@link Coordinate} in this sequence. @param measures the number of measure-ordinates each {@link Coordinate} in this sequence has.

override
copy() → PackedCoordinateSequence
Returns a deep copy of this collection.
override
createCoordinate() → Coordinate
Creates a coordinate for use in this sequence.
inherited
expandEnvelope(Envelope env) → Envelope
Expands the given {@link Envelope} to include the coordinates in the sequence. Allows implementing classes to optimize access to coordinate values.

override
getZ(int index) → double
Returns ordinate Z of the specified coordinate if available.
inherited
hasM() → bool
Checks {@link #getMeasures()} to determine if {@link #getM(int)} is supported.
inherited
hasZ() → bool
Checks {@link #getDimension()} and {@link #getMeasures()} to determine if {@link #getZ(int)} is supported.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
setOrdinate(int index, int ordinate, double value) → void
Sets the ordinate of a coordinate in this sequence.
Warning: for performance reasons the ordinate index is not checked
override
setX(int index, double value) → void
Sets the first ordinate of a coordinate in this sequence.
setY(int index, double value) → void
Sets the second ordinate of a coordinate in this sequence.
size() → int
Returns the number of coordinates in this sequence. @return the size of the sequence
