Member Function Documentation

◆ CalculateNumChildren()

llvm::Expected< uint32_t > lldb_private::formatters::LibCxxMapIteratorSyntheticFrontEnd::CalculateNumChildren ( )

overridevirtual

Implements lldb_private::SyntheticChildrenFrontEnd.

Definition at line 467 of file LibCxxMap.cpp.

◆ GetChildAtIndex()

lldb::ValueObjectSP lldb_private::formatters::LibCxxMapIteratorSyntheticFrontEnd::GetChildAtIndex ( uint32_t idx )

overridevirtual

Implements lldb_private::SyntheticChildrenFrontEnd.

Definition at line 473 of file LibCxxMap.cpp.

References m_pair_sp.

◆ GetIndexOfChildWithName()

llvm::Expected< size_t > lldb_private::formatters::LibCxxMapIteratorSyntheticFrontEnd::GetIndexOfChildWithName ( ConstString name )

overridevirtual

Determine the index of a named child.

Subscript names ("[N]") are, by default, handled automatically. For data types which need custom subscripting behavior - for example a sparse array, disable automatic subscripting with TypeOptions::eTypeOptionCustomSubscripting.

Reimplemented from lldb_private::SyntheticChildrenFrontEnd.

Definition at line 482 of file LibCxxMap.cpp.

References lldb_private::ConstString::AsCString(), and m_pair_sp.

◆ Update()

lldb::ChildCacheState lldb_private::formatters::LibCxxMapIteratorSyntheticFrontEnd::Update ( )

overridevirtual

This function is assumed to always succeed and if it fails, the front-end should know to deal with it in the correct way (most probably, by refusing to return any children).

The return value of Update should actually be interpreted as "ValueObjectSynthetic cache is good/bad". If this function returns lldb::ChildCacheState::eReuse, ValueObjectSynthetic is allowed to use the children it fetched previously and cached. Otherwise, ValueObjectSynthetic must throw away its cache, and query again for children.

Implements lldb_private::SyntheticChildrenFrontEnd.
