Constructor Detail

PatternMatcherAndInvoker

public PatternMatcherAndInvoker(IExpr leftHandSide,
                                IFunctionEvaluator instance,
                                java.lang.String methodName)

Create a pattern-matching rule which invokes the method name in the given instance, if leftHandSide is matching.

Parameters:

Method Detail

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

Overrides:

clone in class PatternMatcher

Throws:

java.lang.CloneNotSupportedException

eval

public IExpr eval(IExpr leftHandSide)

Description copied from class: IPatternMatcher

Match the given left-hand-side and return an evaluated expression

Overrides:

eval in class PatternMatcher

Returns:

null if the match wasn't successful, the evaluated expression otherwise.

equals

public boolean equals(java.lang.Object obj)

Description copied from interface: Predicate

Indicates whether another object is equal to this predicate.

Most implementations will have no reason to override the behavior of Object.equals(java.lang.Object). However, an implementation may also choose to return true whenever object is a Predicate that it considers interchangeable with this one. "Interchangeable" typically means that this.apply(t) == that.apply(t) for all t of type T). Note that a false result from this method does not imply that the predicates are known not to be interchangeable.

Specified by:

equals in interface Predicate<IExpr>

Overrides:

equals in class PatternMatcher

hashCode

public int hashCode()

Overrides:

hashCode in class PatternMatcher
