tuple_is_handleT_tuple_is_handleTupleIsHandleTupleIsHandle (Operator)

Name

tuple_is_handleT_tuple_is_handleTupleIsHandleTupleIsHandle — Test if the internal representation of a tuple is of type handle.

tuple_is_handletuple_is_handleTupleIsHandleTupleIsHandleTupleIsHandle tests if the internal representation of the input tuple TTTTt is of type handle. In that case the value 1 (true) is returned in IsHandleIsHandleIsHandleIsHandleisHandle, otherwise the value 0 (false) is returned. If a tuple consists of handle elements only, IsHandleIsHandleIsHandleIsHandleisHandle can nevertheless be 0 in case the internal representation is H_TYPE_MIXED; see tuple_typetuple_typeTupleTypeTupleTypeTupleType for details.

Exception: Empty input tuple

If the input tuple is empty, the operator returns 1.

HDevelop In-line Operation

HDevelop provides an in-line operation for tuple_is_handletuple_is_handleTupleIsHandleTupleIsHandleTupleIsHandle, which can be used in an expression in the following syntax:

IsHandle := is_handle(T)

Attention

Even if all tuple elements are of type handle, tuple_is_handletuple_is_handleTupleIsHandleTupleIsHandleTupleIsHandle returns 0 (false) if the internal representation of the tuple is of type H_TYPE_MIXED. To test if the elements of the tuple are of type handle, the operator tuple_is_handle_elemtuple_is_handle_elemTupleIsHandleElemTupleIsHandleElemTupleIsHandleElem should be used.
