points

public PGpoint[] points

The points defining this path.

Constructor Detail

PGpath

public PGpath(PGpoint[] points,
              boolean open)

Parameters:

points - the PGpoints that define the path

open - True if the path is open, false if closed

PGpath

public PGpath()

Required by the driver.

PGpath

public PGpath(String s)
       throws SQLException

Parameters:

s - definition of the path in PostgreSQL's syntax.

Throws:

SQLException - on conversion failure

Method Detail

setValue

public void setValue(String s)
              throws SQLException

Description copied from class: PGobject

This method sets the value of this object. It must be overridden.

Overrides:

setValue in class PGobject

Parameters:

s - Definition of the path in PostgreSQL's syntax

Throws:

SQLException - on conversion failure

equals

public boolean equals(Object obj)

Description copied from class: PGobject

This must be overidden to allow comparisons of objects.

Overrides:

equals in class PGobject

Parameters:

obj - Object to compare with

Returns:

true if the two paths are identical

hashCode

public int hashCode()

Description copied from class: PGobject

Compute hash. As equals() use only value. Return the same hash for the same value.

Overrides:

hashCode in class PGobject

Returns:

Value hashcode, 0 if value is null Objects.hashCode(Object)

This must be overidden to allow the object to be cloned.

Overrides:

clone in class PGobject

Returns:

a clone of this instance.
