注释类型概要

注释类型	说明
Deterministic	Specifies that function is deterministic (i.e. returns the same output given the same inputs).
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. it can return different output given the same inputs).
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.
