getResolvedType()

QCString SymbolResolver::getResolvedType

(

)

const

In case a call to resolveClass() points to a typedef or using declaration.

The type name it resolved to is returned via this method.

const

In case a call to resolveClass() resolves to a type member (e.g.

an enum) this method will return it.

isAccessibleFrom()

int SymbolResolver::isAccessibleFrom	(	const Definition *	scope,
		const Definition *	item )

Checks if symbol item is accessible from within scope.

Returns

-1 if item is not accessible or a number indicating how many scope levels up the nearest match was found.

isAccessibleFromWithExpScope()

int SymbolResolver::isAccessibleFromWithExpScope	(	const Definition *	scope,

		const QCString &	explicitScopePart )

Check if symbol item is accessible from within scope, where it has to match the explicitScopePart.

Returns

-1 if item is not accessible or a number indicating how many scope levels up the nearest match was found.

Definition at line 1653 of file symbolresolver.cpp.

resolveClass()

const ClassDef * SymbolResolver::resolveClass	(	const Definition *	scope,
		const QCString &	name,
		bool	maybeUnlinkable = false,
		bool	mayBeHidden = false )

Find the class definition matching name within the scope set.

Parameters

scope	The scope to search from.
name	The name of the symbol.
maybeUnlinkable	include unlinkable symbols in the search.
mayBeHidden	include hidden symbols in the search.

Note

As a result of this call the getters getTypedef(), getTemplateSpec(), and getResolvedType() are set as well.
