Method Detail

combinePrefixPattern

public java.util.regex.Pattern combinePrefixPattern(java.util.List<java.util.regex.Pattern> regexs)
                                             throws java.lang.Exception

Given a group of Patterns, returns a RegExp that globally matches the union of the sets of strings matched by the input RegExp. Since it matches globally, if the input strings have a start-of-input anchor (/^.../), it is ignored for the purposes of unioning.

Parameters:

regexs - non multiline, non-global regexs.

Returns:

Pattern a global regex.

Throws:

java.lang.Exception

decodeEscape

protected static int decodeEscape(java.lang.String charsetPart)

encodeEscape

allowAnywhereFoldCaseAndRenumberGroups
