Annotation Types Summary

Annotation Type	Description
Deterministic	Specifies that function is deterministic (i.e.
Experimental	Annotation that indicates that a class, interface, field or method is experimental, not part of the public API, and subject to change or removal.
Hints	Annotation applied to a user-defined function that gives extra metadata about that function.
NonDeterministic	Specifies that function is NOT deterministic (i.e.
Parameter	Annotation that supplies metadata about a function parameter.
SemiStrict	Annotation applied to a user-defined function that indicates that the function always returns null if one or more of its arguments are null but also may return null at other times.
Strict	Annotation applied to a user-defined function that indicates that the function returns null if and only if one or more of its arguments are null.
