fit

public void fit(double x,
                double y,
                double z)

Extends the envelope so the given point fits in.

Parameters:

fit

public void fit(ShapeEnvelope s)

Extends the envelope so the given envelope fits in.

Parameters:

s -

getByteLength

public int getByteLength()

Specified by:

getByteLength in interface Shape

Returns:

the number of bytes necessary to write this instance.

read

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

Reads only x and y values.

Specified by:

read in interface Shape

offset - where to start reading

Returns:

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

See Also:

Shape.read(byte[], int)

write

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

Writes only x and y values.

Specified by:

write in interface Shape

Returns:

the new offset.

See Also:

Shape.write(byte[], int)

getType

public int getType()

Specified by:

getType in interface Shape

Returns:

zero, because the envelope does not have a type

See Also:

Shape.getType()

getEnvelope

public ShapeEnvelope getEnvelope()

Specified by:

getEnvelope in interface Shape

Returns:

itself, of course

See Also:

Shape.getEnvelope()

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getGeometry

public Geometry getGeometry()

Specified by:

getGeometry in interface Shape

Returns:

null, because an envelope is not a geometry

See Also:

Shape.getGeometry()
