public class PicPointExpression

extends AbstractRegularExpression

An expression for 2D-Point parsing e.g. "(12.3, 34.5)" or "[12.1;-16]" If a coordinate conversion is necessary, it must be computed in the body of the action() method

Constructor Detail

PicPointExpression

public PicPointExpression(java.lang.String prefix,
                          java.lang.String delimiter,
                          java.lang.String postfix)

Method Detail

interpret

public boolean interpret(Context c)
                  throws ParserException

Description copied from class: AbstractRegularExpression

Parses this expression, possibly using Context to fetch the String to interpret if this Expression is a leaf expression.

Specified by:

interpret in class AbstractRegularExpression

---

getPicPoint

public jpicedt.graphic.PicPoint getPicPoint()

Returns the parsed PicPoint

---

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()).
