Create a new ECMAScript interpreter. You can later ask it to interprete code by passing it via evaluate.

Destructor

Force a "context switch". You usually do not need to do that, evaluate() does it too.

[const]

Returns a pointer to the Global object.

[static]

Don't use. May disappear.

Asks the interpreter to evaluate a piece of code. If called more than once the state (global variables, functions etc.) will be preserved between each call.

Parameters:

code	is a string containing the code to be executed.

Returns: True if the code was evaluated successfully, false if an error occured.

Same as above. Only differing in the arguments accepted.

Parameters:

code	is a pointer to an Unicode string containing the code to be executed.
length	number of characters.

Added for convenience in case you have the code in available in internal representation already.

Parameters:

code	is an Unicode string containing the code to be executed.

Call the specified function directly, optionally passing args as a list of arguments. Return value and treatment of errors is analog to the evaluate() calls.

Clear the interpreter's memory. Otherwise, function declarations and global variables will be remembered after each invokation of KJScript::evaluate.

[const]

Returns: Return value from the last call to evaluate(). Null if there hasn't been any.

[const]

Returns: Return code from last call to evaluate(). 0 on success.

[const]

Returns: Return line of last error. -1 if last call didn't have an error.

[const]

Returns: Error message from last call to evaluate(). Empty string if no error occured.

Check the syntax of a piece of code. Return true if the code could be parsed without errors, false otherwise. errorLine() will tell you approximately where the syntax error happened.

Adds a debug() function to the set of pre-defined properties. debug(arg) tries to convert 'arg' to a string and prints the result to stderr. If you want to debug self defined Host Objects this way you should provide them with a toString() method that returns a string.
