jpicedt.graphic.io.parser
Class EnclosingExpression  

java.lang.Object
  jpicedt.graphic.io.parser.AbstractRegularExpression
      jpicedt.graphic.io.parser.EnclosingExpression

All Implemented Interfaces:

ExpressionConstants

---

public class EnclosingExpression

extends AbstractRegularExpression

An expression that can encompass a sub-expression it encloses with markers, e.g. "{" + sub-expression + "}"
The interpret() methods work as follows :

• look up an endMarker matching beginMarker in Context.getRemainingSubstring (that is, skip enclosed blocks with the same markers type)
• set this endMarker as the new Context's endMarker
• save enclosed expression as "value", and interpret it
• restore old Context's endMarker

Method Detail

setChild

public void setChild(AbstractRegularExpression child)

Change the child of this expression to the given expression

interpret

public boolean interpret(Context context)
                  throws ParserException

Call action() with value=enclosed string

Specified by:

interpret in class AbstractRegularExpression

---

getEnclosedString

public java.lang.String getEnclosedString()

---

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()).
