Detailed Description

struct symbol::locator encapsulates a symbol table entry.

Definition at line 79 of file symbol.h.

Constructor & Destructor Documentation

inline

Construct given a name and a provenance.

Parameters

id	The symbol identifier.
source	The `provenance` of the symbol.

Definition at line 95 of file symbol.h.

template<class CharSeq >

symbol::locator::locator ( chewer< CharSeq > & chew )

explicit

Construct given a chewer<CharSeq>

Template Parameters

CharSeq A character-sequence type

Parameters

chew	On entry, a `chewer<Charseq>` positioned at the offset in the associated `CharSeq` from which to scan for an identifier. On return`chew` is positioned to the first offset not consumed.

If no identifier is scanned the null locator results.
