# File 'lib/oci8/metadata.rb', line 1553 def (OCI8::Metadata::Type) end |
#type_name ⇒ Object
Returns a string which is the type name, or the package name in the case of package local types. The returned value will contain the type name if the datatype is :named_type
or :ref
. If the datatype is :named_type
, the name of the named datatype’s type is returned. If the datatype is :ref
, the type name of the named datatype pointed to by the REF is returned.
