Known Subclasses:: And, Each, MatchFirst, Or

Abstract subclass of ParserElement, for combining and post-processing parsed tokens.

Method Summary
	`__init__(self, exprs, savelist)`
	`__getitem__(self, i)`
	`__str__(self)`
	`append(self, other)`
	`ignore(self, other)` Define expression to be ignored (e.g., comments) while doing pattern matching; may be called repeatedly, to define multiple comment or other ignorable patterns.
	`leaveWhitespace(self)` Extends leaveWhitespace defined in base class, and also invokes leaveWhitespace on all contained expressions.
	`setResultsName(self, name, listAllMatches)` Define name for referencing matching tokens as a nested attribute of the returned parse results.
	`streamline(self)`
	`validate(self, validateTrace)` Check defined expressions for valid structure, check for infinite recursive definitions.

Instance Method Details

ignore(self, other)

Define expression to be ignored (e.g., comments) while doing pattern matching; may be called repeatedly, to define multiple comment or other ignorable patterns.

Overrides:: parserFwk.pyparsing.ParserElement.ignore (inherited documentation)

leaveWhitespace(self)

Extends leaveWhitespace defined in base class, and also invokes leaveWhitespace on all contained expressions.

Overrides:: parserFwk.pyparsing.ParserElement.leaveWhitespace

setResultsName(self, name, listAllMatches=False)

Define name for referencing matching tokens as a nested attribute of the returned parse results. NOTE: this returns a *copy* of the original ParserElement object; this is so that the client can define a basic element, such as an integer, and reference it in multiple places with different names.

Overrides:: parserFwk.pyparsing.ParserElement.setResultsName (inherited documentation)

validate(self, validateTrace=[])

Check defined expressions for valid structure, check for infinite recursive definitions.

Overrides:: parserFwk.pyparsing.ParserElement.validate (inherited documentation)
