Improve documentation of UnknownArrayHandle::IsType
Under some circumstances, IsType
can return false for a type that
exactly matches the type used to create the UnknownArrayHandle
.
This is because types like ArrayHandleCast
get converted to
the array they contain. Thus, IsType
will return false when it
is expected to be true. In most cases, you should use
CanConvert
. The IsType
documentation now points you there.
