abstract fun descriptorString(): String!
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 {@jvms 4.3}. The result descriptor string can be used to produce a java.lang.constant.ConstantDesc nominal descriptor. Otherwise, the result string is not a type descriptor. No java.lang.constant.ConstantDesc nominal descriptor can be produced from the result string.
