Constructor Detail

RegExp.Union

public RegExp.Union(RegExp<A> left,
                    RegExp<A> right)

Creates a Union regular expression that matches any string that is matched by (at least one of) left and right.

Method Detail

accept

public <Res> Res accept(RegExp.Visitor<A,Res> visitor)

Description copied from class: RegExp

Method for the visitor pattern. This method will dynamically select and execute the visit method of the visitor that corresponds to the dynamic type of the regular expression. E.g., in the case of a regular expression that is a RegExp.Concat object, accept executes the code of visit(RegExp.Concat).

Overrides:

accept in class RegExp<A>

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class java.lang.Object

_hashCode

protected int _hashCode()

Description copied from class: RegExp

Does the real work behing hashCode.

Specified by:

_hashCode in class RegExp<A>

See Also:

RegExp.hashCode()

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

allTransTerms

public java.util.List<RegExp<A>> allTransTerms()

Returns all transitive terms of this Union. More details: this Union regexp may be the root of a subtree of Union internal nodes, modeling the union of several regexps: e.g., a|((b|c)|d). This method returns all the leaves of this subtree; for the previous example, it returns [a,b,c,d].
