Class PSTColorExpression

      jpicedt.format.input.util.SequenceExpression
          jpicedt.format.input.pstricks.PSTColorExpression

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.

public PSTColorExpression(Pool pl,
                          String tag,
                          PicAttributeName<Color> attributeName,
                          Pool.Key<PicAttributeSet> attributeSetKey)

Parameters:

pl - parser's pool
