Class RangeReplacer
java.lang.Objectcom.trapezium.chisel.RangeReplacer
- public class RangeReplacer
- extends java.lang.Object
The RangeReplacer handles replacement of sequences of tokens. Each sequence to be replaced is registered for replacement, along with the Optimizer object handling the replacement and a parameter that gets passed to the Optimizer object. NOTE: this does not handle embedded replacements. Only the first replacement range found is handled.
