ScriptObject

General Object class. Similar to JavaScript, this class works as a dictionary but the keys must be strings. Native D objects can be stored in any ScriptObject or derived class by assigning it to its nativeObject field. This is also the base class for arrays, strings, and functions so that those script values can have dictionary entries assigned to them as well.

Constructors

this this(string typename, ScriptObject proto, Object native): Constructs a new ScriptObject that can be stored inside ScriptValue.
this this(string typename): Empty constructor that leaves prototype, and nativeObject as null.

Functions

addGetterProperty void addGetterProperty(string propName, ScriptFunction getter): Add a getter. Getters should be added to a constructor function's "prototype" field
addSetterProperty void addSetterProperty(string propName, ScriptFunction setter): Add a setter. Setters should be added to a constructor function's "prototype" field
assignField ScriptAny assignField(string name, ScriptAny value): Assigns a field to the current object. This does not call any setters.
dictionary auto dictionary(): This property provides direct access to the dictionary
findGetter ScriptFunction findGetter(string propName): Find a getter in the prototype chain
findSetter ScriptFunction findSetter(string propName): Find a setter in the prototype chain
getOwnFieldOrPropertyDescriptors ScriptObject getOwnFieldOrPropertyDescriptors(): Undocumented in source. Be warned that the author may not have intended to support it.
getOwnPropertyOrFieldDescriptor ScriptObject getOwnPropertyOrFieldDescriptor(string propName): Returns a property descriptor without searching the prototype chain. The object returned is an object possibly containing get, set, or value fields.
getters auto getters(): getters property
hasGetter bool hasGetter(string propName): Determines if there is a getter for a given property
hasOwnFieldOrProperty bool hasOwnFieldOrProperty(string propOrFieldName): Tests whether or not a property or field exists in this object without searching the __proto__ chain.
hasSetter bool hasSetter(string propName): Determines if there is a setter for a given property
lookupField ScriptAny lookupField(string name): Looks up a field through the prototype chain. Note that this does not call any getters because it is not possible to pass an Environment to opIndex.
name string name(): name property
nativeObject T nativeObject(): If a native object was stored inside this ScriptObject, it can be retrieved with this function. Note that one must always check that the return value isn't null because all functions can be called with invalid "this" objects using functionName.call.
nativeObject T nativeObject(T obj): Native object can also be written because this is how binding works. Constructors receive a premade ScriptObject as the "this" with the name and prototype already set. Native D constructor functions have to set this property.
opIndex ScriptAny opIndex(string index): Shorthand for lookupField.
opIndexAssign ScriptAny opIndexAssign(T value, string index): Shorthand for assignField
prototype auto prototype(): prototype property
prototype auto prototype(ScriptObject proto): prototype property (setter)
setters auto setters(): setters property
toString string toString(): Returns a string with JSON like formatting representing the object's key-value pairs as well as any nested objects. In the future this will be replaced and an explicit function call will be required to print this detailed information.
