Detailed Description

A multi namespace is essentially a namespace, with a list of namespaces.

It's difference with namespacet is that it can use more than two symbol tables to lookup symbols in.

Member Function Documentation

◆ add()

void multi_namespacet::add ( const symbol_table_baset & symbol_table )

inline

Add symbol table to the list of symbol tables this multi-namespace is working with.

Parameters

symbol_table Reference to the symbol table to be added to this namespace.

Definition at line 165 of file namespace.h.

◆ lookup() [1/5]

const symbolt& namespace_baset::lookup

inline

Lookup a symbol in the namespace.

Parameters

name	The name of the symbol to lookup.

Returns: A reference to the symbol found.

Remarks: : It is a PRECONDITION that the symbol name exists in the namespace.

Definition at line 46 of file namespace.h.

◆ lookup() [2/5]

bool multi_namespacet::lookup	(	const irep_idt &	name,
		const symbolt *&	symbol
	)		const

overridevirtual

See documentation for namespace_baset::lookup().

Iterate through the symbol tables in the multi-namespace and lookup the symbol.

Parameters

name	The name of the symbol to be looked up.
symbol	The const pointer to the reference of the symbol if it's found during lookup.

Returns: False if the symbol was found, True otherwise.

Reimplemented from namespacet.

Definition at line 199 of file namespace.cpp.

◆ lookup() [3/5]

virtual bool namespace_baset::lookup

Searches for a symbol named name.

Iff found, set symbol to point to the symbol and return false; else symbol is unmodified and true is returned. With multiple symbol tables, symbol_table1 is searched first and then symbol_table2.

Returns: False iff the requested symbol is found in at least one of the tables.

◆ lookup() [4/5]

const symbolt & namespace_baset::lookup

Generic lookup function for a symbol expression in a symbol table.

Parameters

expr	The symbol expression to lookup.

Returns: The symbol found in the namespace.

Remarks: The lookup function called assumes that the symbol we are looking for exists in the symbol table. If it doesn't, it hits an INVARIANT.

Definition at line 58 of file namespace.cpp.

◆ lookup() [5/5]

const symbolt & namespace_baset::lookup

Generic lookup function for a tag type in a symbol table.

Parameters

type	The tag type to lookup.

Returns: The symbol found in the namespace.

Remarks: The lookup function called assumes that the tag symbol we are looking for exists in the symbol table. If it doesn't, it hits an INVARIANT.

Definition at line 59 of file namespace.cpp.

◆ smallest_unused_suffix()

std::size_t multi_namespacet::smallest_unused_suffix ( const std::string & prefix ) const

overridevirtual

See documentation for namespace_baset::smallest_unused_suffix().

Find smallest unused suffix in the all the symbol tables.

Parameters

prefix The prefix to find smallest unused suffix of.

Returns: The smallest prefix size.

Reimplemented from namespacet.

Definition at line 183 of file namespace.cpp.
