Known Subclasses:

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

Instance Methods
 
__init__(self, exprs, savelist=False)
x.__init__(...) initializes x; see x.__class__.__doc__ for signature
source code
 
__getitem__(self, i) source code
 
append(self, other) source code
 
leaveWhitespace(self)
Extends leaveWhitespace defined in base class, and also invokes leaveWhitespace on all contained expressions.
source code
 
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.
source code
 
__str__(self)
str(x)
source code
 
streamline(self) source code
 
setResultsName(self, name, listAllMatches=False)
Define name for referencing matching tokens as a nested attribute of the returned parse results.
source code
 
validate(self, validateTrace=[])
Check defined expressions for valid structure, check for infinite recursive definitions.

Method Details

__init__(self, exprs, savelist=False)
(Constructor)

source code 

x.__init__(...) initializes x; see x.__class__.__doc__ for signature

Overrides: object.__init__
(inherited documentation)

leaveWhitespace(self)

source code 

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

Overrides: ParserElement.leaveWhitespace

ignore(self, other)

source code 

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: ParserElement.ignore
(inherited documentation)

__str__(self)
(Informal representation operator)

source code 

str(x)

Overrides: object.__str__
(inherited documentation)

streamline(self)

source code 
Overrides: ParserElement.streamline

setResultsName(self, name, listAllMatches=False)

source code 

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: ParserElement.setResultsName
(inherited documentation)

validate(self, validateTrace=[])

source code 

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

Overrides: ParserElement.validate
(inherited documentation)
