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

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("(", ",", ")")
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:
