Detailed Description

 KJScript ()

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

KJScript ()

Destructor

bool  evaluate (const char *code)

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:

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

bool  evaluate (const KJS::KJSO &thisV, const QChar *code, unsigned int length)

Same as above. Only differing in the arguments accepted.

Parameters:

bool  evaluate (const KJS::UString &code)

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

Parameters:

void  clear ()

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

KJS::ImpreturnValue ()

[const]

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

int  errorType ()

[const]

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

const char * errorMsg ()

[const]

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

void  enableDebug ()

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.
