Detailed Description

An instance of a Property Descriptor, see Ecma-262 6.2.4.

Properties in a descriptor are present or absent. If you do not set enumerable, configurable, and writable, they are absent. If value, get, or set are absent, but you must specify them in the constructor, use empty handles.

Accessors get and set must be callable or undefined if they are present.

Note: Only query properties if they are present, i.e., call x() only if has_x() returns true.

// var desc = {writable: false}
v8::PropertyDescriptor d(Local<Value>()), false);
d.value(); // error, value not set
if (d.has_writable()) {
  d.writable(); // false
}
 
// var desc = {value: undefined}
v8::PropertyDescriptor d(v8::Undefined(isolate));
 
// var desc = {get: undefined}
v8::PropertyDescriptor d(v8::Undefined(isolate), Local<Value>()));
