Methods

Modifier and Type	Method and Description
double	getX() Gets the X coordinate of the current vertex.
double	getY() Gets the Y coordinate of the current vertex.
boolean	hasNext() This checks if there is a vertex available from the stream.
boolean	isEndOfPart() Checks if the current vertex ends a part of the geometry, meaning vertices that follow will be from a new part.
boolean	next() This advances the internal pointer to the next vertex.

JTSGeometryVertexStream

public JTSGeometryVertexStream(com.vividsolutions.jts.geom.Geometry geom)

Method Detail

hasNext

public boolean hasNext()

This checks if there is a vertex available from the stream.

Specified by:

hasNext in interface weave.geometrystream.IGeometryVertexStream

Returns:

true if there is a next vertex available from the stream, meaning a call to next() will succeed.

next

public boolean next()

This advances the internal pointer to the next vertex. Initially, the pointer points before the first vertex. This function must be called before getX() and getY() are called.

Specified by:

next in interface weave.geometrystream.IGeometryVertexStream

Returns:

true if advancing the vertex pointer succeeded, meaning getX() and getY() can now be called.

isEndOfPart

public boolean isEndOfPart()

Checks if the current vertex ends a part of the geometry, meaning vertices that follow will be from a new part.

Specified by:

isEndOfPart in interface weave.geometrystream.IGeometryVertexStream

getX

public double getX()

Gets the X coordinate of the current vertex.

Specified by:

getX in interface weave.geometrystream.IGeometryVertexStream

getY

public double getY()

Gets the Y coordinate of the current vertex.

Specified by:

getY in interface weave.geometrystream.IGeometryVertexStream
