Detailed Description

This class tracks the state and results of a TypeQuery.

Any mutable state required for type lookups and the results are tracked in this object.

Constructor & Destructor Documentation

TypeResults()

lldb_private::TypeResults::TypeResults ( )

default

Construct a type results object.

Member Function Documentation

AlreadySearched()

bool TypeResults::AlreadySearched

(

lldb_private::SymbolFile *

sym_file

)

Check if a SymbolFile object has already been searched by this type match object.

This function will add sym_file to the set of SymbolFile objects if it isn't already in the set and return false. Returns true if sym_file was already in the set and doesn't need to be searched.

Any clients that search for types should first check that the symbol file has not already been searched. If this function returns true, the type search function should early return to avoid duplicating type searchihng efforts.

Parameters

[in]

sym_file

A SymbolFile pointer that will be used to track which symbol files have already been searched.

Returns

True if the symbol file has been search already, false otherwise.

InsertUnique()

bool TypeResults::InsertUnique

(

const lldb::TypeSP &

)

When types that match a TypeQuery are found, this API is used to insert the matching types.

Returns

True if the type was added, false if the type_sp was already in the results.
