Detailed Description

Forward declaration of an expression to be defined later -
   used for recursive grammars, such as algebraic infix notation.
   When the expression is known, it is assigned to the Forward variable using the '<<' operator.

   Note: take care when assigning to Forward not to overlook precedence of operators.
   Specifically, '|' has a lower precedence than '<<', so that::
      fwdExpr << a | b | c
   will actually be evaluated as::
      (fwdExpr << a) | b | c
   thereby leaving b and c out as parseable alternatives.  It is recommended that you
   explicitly group the values inserted into the Forward::
      fwdExpr << (a | b | c)

def blockit::external::pyparsing::Forward::__str__

(

self

)

Reimplemented from blockit::external::pyparsing::ParseElementEnhance.

Reimplemented in blockit::external::pyparsing::_ForwardNoRecurse.

Definition at line 2938 of file pyparsing.py.

def blockit::external::pyparsing::Forward::copy

(

self

)

Make a copy of this ParserElement.  Useful for defining different parse actions
   for the same parsing pattern, using copies of the original parse element.

Reimplemented from blockit::external::pyparsing::ParserElement.

Definition at line 2953 of file pyparsing.py.

def blockit::external::pyparsing::Forward::leaveWhitespace

(

self

)

Disables the skipping of whitespace before matching the characters in the
   ParserElement's defined pattern.  This is normally only used internally by
   the pyparsing module, but may be needed in some whitespace-sensitive grammars.

Reimplemented from blockit::external::pyparsing::ParseElementEnhance.

def blockit::external::pyparsing::Forward::streamline

(

self

Reimplemented from blockit::external::pyparsing::ParseElementEnhance.

Definition at line 2924 of file pyparsing.py.

def blockit::external::pyparsing::Forward::validate	(		self,
			validateTrace = []
	)

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