Method Detail

getByteLength

public int getByteLength()

Specified by:

getByteLength in interface Shape

Returns:

the number of bytes necessary to write this instance.

readPolyline

Description copied from interface: Shape

Reads the object from a byte array.

Specified by:

read in interface Shape

offset - where to start reading

Returns:

the new offset or -1, if the type was wrong.

write

public int write(byte[] bytes,
                 int offset)

Description copied from interface: Shape

Writes the object to a byte array.

Specified by:

write in interface Shape

Returns:

the new offset.

getType

public int getType()

Specified by:

getType in interface Shape

Returns:

the type of the shape

getEnvelope

public ShapeEnvelope getEnvelope()

Specified by:

getEnvelope in interface Shape

Returns:

the shapes' envelope, or null, if it has none
