Method Detail

getShapeType

public ShapeType getShapeType()

Returns the shapefile shape type value for a point

Specified by:

getShapeType in interface ShapeHandler

Returns:

int Shapefile.POINT

getLength

public int getLength(java.lang.Object geometry)

Calcuates the record length of this object.

Specified by:

getLength in interface ShapeHandler

Parameters:

geometry - The geometry to analyze.

Returns:

int The length of the record that this shapepoint will take up in a shapefile

read

public java.lang.Object read(java.nio.ByteBuffer buffer,
                             ShapeType type)

Description copied from interface: ShapeHandler

Read a geometry from the ByteBuffer. The buffer's position, byteOrder, and limit are set to that which is needed. The record has been read as well as the shape type integer. The handler need not worry about reading unused information as the ShapefileReader will correctly adjust the buffer position after this call.

Specified by:

read in interface ShapeHandler

Parameters:

buffer - The ByteBuffer to read from.

Returns:

A geometry object.

write

public void write(java.nio.ByteBuffer buffer,
                  java.lang.Object geometry)

Description copied from interface: ShapeHandler

Write the geometry into the ByteBuffer. The position, byteOrder, and limit are all set. The handler is not responsible for writing the record or shape type integer.

Specified by:

write in interface ShapeHandler

Parameters:

buffer - The ByteBuffer to write to.

geometry - The geometry to write.
