Detailed Description

A ValueObject that obtains its children from some source other than real information.

This is currently used to implement Python-based children and filters but you can bind it to any source of synthetic information and have it behave accordingly.

◆ MightHaveChildren()

bool ValueObjectSynthetic::MightHaveChildren ( )

overridevirtual

Find out if a ValueObject might have children.

This call is much more efficient than CalculateNumChildren() as it doesn't need to complete the underlying type. This is designed to be used in a UI environment in order to detect if the disclosure triangle should be displayed or not.

This function returns true for class, union, structure, pointers, references, arrays and more. Again, it does so without doing any expensive type completion.

Returns: Returns true if the ValueObject might have children, or false otherwise.
