method_exists
.. method_exists(f, Tuple type) -> Bool
Determine whether the given generic function has a method matching the given :obj:`Tuple` of argument types.
.. doctest::
julia> method_exists(length, Tuple{Array})
trueExamples
The method_exists function in Julia is used to determine whether a given generic function has a method matching a specific tuple of argument types.
julia> method_exists(f, Tuple type) -> BoolHere's an example of how to use method_exists:
julia> method_exists(length, Tuple{Array})
trueIn this example, we check if the length function has a method that takes an Array as an argument. The method_exists function returns true if such a method exists and false otherwise.
