               ParseExpression

Known Subclasses:
And, 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)
  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.

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:
pyparsing.ParserElement.ignore (inherited documentation)

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 ParseElement 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:
pyparsing.ParserElement.setResultsName (inherited documentation)

validate(self, validateTrace=[])

Check defined expressions for valid structure, check for infinite recursive definitions.
Overrides:
pyparsing.ParserElement.validate (inherited documentation)
