Class RegExpTerm

A regular expression term, that is, a syntactic part of a regular expression.

Regular expression terms may occur as part of a regular expression literal, such as /[a-z]+/, or as part of a string literal, such as "[a-z]+".

Note that some terms will occur as part of a string literal that isn’t actually interpreted as regular expression at runtime. Use isPartOfRegExpLiteral or isUsedAsRegExp to check if a term is really used as a regular expression.

Examples:

((ECMA|Java)[sS]cript)*$
((ECMA|Java)[sS]cript)*
(ECMA|Java)
$
