◆ CalculateNumChildren()

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

◆ GetChildAtIndex()

overridevirtual

References lldb_private::ConstString::AsCString(), lldb_private::formatters::ExtractIndexFromString(), and lldb_private::ConstString::GetCString().

◆ GetValueAt()

ValueObjectSP lldb_private::formatters::MsvcStlTreeSyntheticFrontEnd::GetValueAt	(	size_t	idx,
		size_t	max_depth )

private

Returns the ValueObject for the _Tree_node at index idx.

Parameters

[in]	idx	The child index that we're looking to get the value for.
[in]	max_depth	The maximum search depth after which we stop trying to find the node for.

Returns: On success, returns the ValueObjectSP corresponding to the _Tree_node's _Myval member. On failure, nullptr is returned.

◆ Update()

lldb::ChildCacheState lldb_private::formatters::MsvcStlTreeSyntheticFrontEnd::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.
