Detailed Description

Abstract base class for expressions.

Constructor & Destructor Documentation

virtual pegmatite::Expr::~Expr ( )

virtual

Virtual destructor for safe overloading.

Note that generally expression objects are not meant to be deallocated, as they can be used by multiple parsers.

Defined out-of-line to avoid emitting vtables in every translation unit that includes this header.

virtual void pegmatite::Expr::dump ( ) const

pure virtual

Dump the current rule.

Used for debugging.

virtual bool pegmatite::Expr::parse_non_term ( Context & con ) const

pure virtual

Parse this expression as a non-terminal.

Non-terminals are permitted to contain whitespace around compound expressions, as defined by the whitespace rule in the context.

virtual bool pegmatite::Expr::parse_term ( Context & con ) const

pure virtual

Parse this expression as a terminal.

Terminals are exact matches for the specified expression, without any whitespace.
