public class UserDefinedColorExpression
extends jpicedt.graphic.io.parser.AlternateExpression
implements jpicedt.graphic.io.parser.ExpressionConstants

Parse statement defining user-colours, that is :

Colour names may contain letters and numbers. Spaces are NOT allowed, except as separators b/w colour numbers. New colours are then added to the pool's hashtable associated with key = PstricksParser.KEY_USER_COLOURS.

Method Detail

toString

public java.lang.String toString()
Description copied from class: java.lang.Object
Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).
