◆ GetKeyValuePair()

ValueObjectSP lldb_private::formatters::LibcxxStdMapSyntheticFrontEnd::GetKeyValuePair	(	size_t	idx,
		size_t	max_depth )

private

Returns the ValueObject for the __tree_node type that holds the key/value pair of the node at index idx.

Parameters

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

Returns: On success, returns the ValueObjectSP corresponding to the __tree_node's __value_ member (which holds the key/value pair the formatter wants to display). On failure, will return nullptr.

◆ Update()

lldb::ChildCacheState lldb_private::formatters::LibcxxStdMapSyntheticFrontEnd::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.
