A method is dead if it is from source, has no liveness causes, is not a compiler generated method and is not a dead method with a purpose, such as a constructor designed to suppress the default constructor.

contains	Holds if this element transitively contains the specified element `e`.	from Element
fromSource	Holds if this element pertains to a source file.	from Element

getACallee	Gets a callee that may be called from this callable.	from Callable
