Method Details

descriptorString

String descriptorString()

Returns the descriptor string for this TypeDescriptor object. If this TypeDescriptor object can be described in nominal form, then this method returns a type descriptor as specified in JVMS 4.3. The result descriptor string can be used to produce a nominal descriptor. Otherwise, the result string is not a type descriptor. No nominal descriptor can be produced from the result string.

Returns:
