Detailed Description

Functions to manage namespace search paths.

There are two open commands: open foo; this adds "foo" to the search path, and allows access to items that would be accessible in the foo namespace context (w.r.t. exports)

open foo -> bar; this renames foo to bar (without changing the export definitions)

findAll()

list_t * ActOpen::findAll	(	ActNamespace *	cur,
		const char *	s
	)

Find namespace in the current context, given the context of opens

Parameters

cur	is the current default namespace
s	is the name of the namespace to be located

Returns

a list of namespaces, if found, NULL otherwise

findType()

ActNamespace * ActOpen::findType	(	ActNamespace *	cur,
		const char *	s
	)

Find namespace that contains the specified type, given the context of opens

Parameters

cur	is the current default namespace
s	is the name of the type to be located

Returns

namespace if found, NULL otherwise

Open()

int ActOpen::Open	(	ActNamespace *	ns,
		const char *	newname = NULL
	)

Opens a namespace (optionally as a new name)

Parameters

ns	is the namespace to be opened
newname	is the new name to be assigned to the namespace. If NULL, then the namespace is simply opened
