PsUnitLengthExpression (jPicEdt 1.4.1_03 API documentation)

java.lang.Object
- jpicedt.format.input.util.AbstractRegularExpression
- - jpicedt.format.input.util.SequenceExpression
  - - jpicedt.format.input.pstricks.PsUnitLengthExpression

All Implemented Interfaces:

ExpressionConstants
```
public class PsUnitLengthExpression
extends SequenceExpression
implements ExpressionConstants
```
Used by PSTParamExpression to parse statement involving the 4 pstricks length registers, that is "unit=1mm,xunit=1mm,yunit=1mm,runit=1mm" (or pt or cm), where setting "unit" sets "xunit", "yunit" and "runit" simultaneously.
Parsed value are stored in Pool's hashtable using PstricksParser.KEY_X_UNIT and related keys.
Note that default PsTricks's unit is 1cm ! (whereas jPicEdt default unit is 1mm) hence no unit leads to pstXunit = 0.1, etc...
Allowed syntaxs are : "0.11" (i.e. cm), "0.11mm", "0.11cm", "0.11pt"
According to PsTricks's doc, whitespaces are allowed ONLY after the comma (see PsTricks doc. page 6), though here we use a StatementExpression which swallows them, which makes it less stringent.
