Detailed Description

An identifier.

This is just a simple string-like class with constant-time comparison. String manipulation is not provided by intention, as that would lead to generation of redundant unique string pointers. Use std::string or gc_string to create the string first, if needed.

Constructor & Destructor Documentation

more::gen::identifier::identifier (    )  [inline]

Construct an invalid identifier. Ideally this ctor would create an anonymous unique identifier, but that may have lead to many redundant allocations declared and defined separately.

more::gen::identifier::identifier (  char const *    str )

Construct an object identified by "str".

Member Function Documentation

char const* more::gen::identifier::c_str (    )  const [inline]

Return a C string which is lexically equal to the string this object was constructed from.

bool more::gen::identifier::is_defined (    )  const [inline]

True iff the identifier is valid.

size_type more::gen::identifier::length (    )  const [inline]

bool more::gen::identifier::operator!= (  identifier const &    rhs )  const [inline]

True if the identifiers are different.

bool more::gen::identifier::operator< (  identifier const &    rhs )  const [inline]

Provides an arbitrary ordering if identifiers.

bool more::gen::identifier::operator== (  identifier const &    rhs )  const [inline]

Equivalent to "strcmp(c_str(), rhs.c_str()) == 0", but faster.

void more::gen::identifier::sync (  io::syncstream &    )
