Class ChangeWeightLexerMatcher

java.lang.Object

com.massa.dsl.matcher.AbstractLexerMatcherWrapper

com.massa.dsl.matcher.ChangeWeightLexerMatcher

All Implemented Interfaces:

MatcherAutoCompleter, Documented, LexerMatcher, Serializable

public class ChangeWeightLexerMatcher
extends AbstractLexerMatcherWrapper

Wraps a LexerMatcher to dynamically change the computed weight.
The weight computed by the wrapped matcher will be changed if this rule is respected : the match result can't be changed.
If weight is lesser than zero, it won't be changed as it's unuseful. Otherwise, it the weightDiff is negative and to big, the computed new weight will be zero.
