Interpreter objects can be used to evaluate ECMAScript code. Each interpreter has a global object which is used for the purposes of code evaluation, and also provides access to built-in properties such as " Object" and "Number".
Interpreter (const Object &global)
| Interpreter |
Creates a new interpreter. The supplied object will be used as the global object for all scripts executed with this interpreter. During constuction, all the standard properties such as "Object" and "Number" will be added to the global object.
Note: You should not use the same global object for multiple interpreters.
This is due do the fact that the built-in properties are set in the constructor, and if these objects have been modified from another interpreter (e.g. a script modifying String.prototype), the changes will be overridden.
Parameters:
global | The object to use as the global object for this interpreter |
Interpreter ()
| Interpreter |
Creates a new interpreter. A global object will be created and initialized with the standard global properties.
~Interpreter ()
| ~Interpreter |
Object globalObject ()
| globalObject |
[const]
Returns the object that is used as the global object during all script execution performed by this interpreter
ExecState * globalExec ()
| globalExec |
Returns the execution state object which can be used to execute scripts using this interpreter at a the "global" level, i.e. one with a execution context that has the global object as the "this" value, and who's scope chain contains only the global object.
Note: this pointer remains constant for the life of the interpreter and should not be manually deleted.
Returns: The interpreter global execution state object
bool checkSyntax (const UString &code)
| checkSyntax |
Parses the supplied ECMAScript code and checks for syntax errors.
Parameters:
code | The code to check |
Returns: true if there were no syntax errors in the code, otherwise false
Completion evaluate (const UString &code, const Value &thisV = Value())
| evaluate |
Evaluates the supplied ECMAScript code.
Since this method returns a Completion, you should check the type of completion to detect an error or before attempting to access the returned value. For example, if an error occurs during script execution and is not caught by the script, the completion type will be Throw.
If the supplied code is invalid, a SyntaxError will be thrown.
Parameters:
code | The code to evaluate |
thisV | The value to pass in as the "this" value for the script execution. This should either be Null() or an Object. |
Returns: A completion object representing the result of the execution.
InterpreterImp * imp ()
| imp |
Returns the implementation object associated with this interpreter. Only useful for internal KJS operations.
Object builtinObject ()
| builtinObject |
[const]
Returns the builtin "Object" object. This is the object that was set as a property of the global object during construction; if the property is replaced by script code, this method will still return the original object.
Returns: The builtin "Object" object
