Class PicPointExpression

java.lang.Object

jpicedt.format.input.util.AbstractRegularExpression

jpicedt.format.input.util.PicPointExpression

All Implemented Interfaces:

ExpressionConstants

Direct Known Subclasses:

LaTeXPicPointExpression, PSTPicPointExpression

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

Since:

jpicedt 1.3

Constructor Detail

PicPointExpression

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

Parameters:

prefix - the opening bracket e.g. "("

delimiter - the string that delimits the border between the two numbers e.g. ","

postfix - the closing bracket e.g. ")" A typical use would be : PicPointExpression("(", ",", ")")

Method Detail

interpret

public boolean interpret(Context c)
                  throws REParserException

Description copied from class: AbstractRegularExpression

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

Specified by:

interpret in class AbstractRegularExpression

Returns:

TRUE if expr has been found send a ParserEvent with value = parsed PicPoint

Throws:

IncompleteSequence - exception if there's nothing after the prefix...

REParserException - if an error occur during parsing

getPicPoint

public PicPoint getPicPoint()

Returns the parsed PicPoint

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
