ScriptFunction

This class encapsulates all types of script functions including native D functions and delegates. A native function must first be wrapped in this class before it can be given to a ScriptAny assignment. When an object is created with "new FunctionName()" its __proto__ is assigned to the function's "prototype" field. This allows OOP in the scripting language and is analogous to JavaScript.

class ScriptFunction : ScriptObject {

import mildew.nodes : StatementNode;;

import mildew.interpreter : Interpreter;;

this(string fname, NativeFunction nfunc, bool isClass);

this(string fname, NativeDelegate ndele, bool isClass);

this(string fnname, string[] args, StatementNode[] statementNodes, Context clos, bool isClass);

auto statementNodes();

}

Constructors

this this(string fname, NativeFunction nfunc, bool isClass): Constructs a new ScriptFunction out of a native D function.
this this(string fname, NativeDelegate ndele, bool isClass): Constructs a new ScriptFunction out of a native D delegate.
this this(string fnname, string[] args, StatementNode[] statementNodes, Context clos, bool isClass): Constructor for creating script defined functions.

Members

Enums

Type enum Type: The type of function held by the object

Functions

argNames auto argNames(): Property argNames
closure auto closure(): Property closure
closure auto closure(Context clos): Undocumented in source. Be warned that the author may not have intended to support it.
functionName auto functionName(): Returns the name of the function
functionName auto functionName(string fnName): Sets the function name
nativeDelegate auto nativeDelegate(): get the delegate only if it is one
nativeFunction auto nativeFunction(): get the native function ONLY if it is one
statementNodes auto statementNodes(): Property statementNodes
toString string toString(): Returns a string representing the type and name.
type auto type(): Returns the type of function stored, such as native function, delegate, or script function

Static functions

emptyFunction ScriptFunction emptyFunction(string name, bool isClass): used by the parser for missing constructors in classes that don't extend

Inherited Members

From ScriptObject

name string name(): name property
getters auto getters(): getters property
setters auto setters(): setters property
prototype auto prototype(): prototype property
prototype auto prototype(ScriptObject proto): prototype property (setter)
dictionary auto dictionary(): This property provides direct access to the dictionary
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
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 a Context to opIndex.
opIndex ScriptAny opIndex(string index): Shorthand for lookupField.
assignField ScriptAny assignField(string name, ScriptAny value): Assigns a field to the current object. This does not call any setters.
hasGetter bool hasGetter(string propName): Determines if there is a getter for a given property
hasSetter bool hasSetter(string propName): Determines if there is a setter for a given property
opIndexAssign ScriptAny opIndexAssign(T value, string index): Shorthand for assignField
getOwnPropertyDescriptor ScriptObject getOwnPropertyDescriptor(string propName): Undocumented in source. Be warned that the author may not have intended to support it.
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 in case of inheritance by script
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.
_dictionary ScriptAny[string] _dictionary;: The dictionary of key-value pairs
_getters ScriptFunction[string] _getters;: The lookup table for getters
_setters ScriptFunction[string] _setters;: The lookup table for setters
