Package jpicedt.format.input.pstricks

Class PSTColorExpression

java.lang.Object

jpicedt.format.input.util.AbstractRegularExpression

jpicedt.format.input.util.SequenceExpression

jpicedt.format.input.pstricks.PSTColorExpression

All Implemented Interfaces:

ExpressionConstants

public class PSTColorExpression
extends SequenceExpression

Used by PSTParametersExpression to parse statements involving colours, for instance "linecolor=green" (predefined colour) or "fillcolor=MyGray" (user-defined colours).

If no pstricks's native colour matches the RHS, we fetch a HashMap from the Pool's hashtable (value associated with key PstricksParser.KEY_USER_COLOURS) and look up the given colour ; this HashMap may've been filled by UserDefinedColorExpression in the course of the parsing process.

Constructor Detail

PSTColorExpression

public PSTColorExpression(Pool pl,
                          java.lang.String tag,
                          PicAttributeName attributeName,
                          Pool.Key attributeSetKey)

Parameters:

pl - parser's pool

tag - LHS tag (e.g. "linecolor" or "fillcolor") for the StatementExpression

attribute - name of attribute to modify (must be a predefined PicAttributeName of type "Color")

attributeSetKey - used to fetch the attribute set in which parsed parameters are stored.
