• Constructor Detail

  • HtmlUnitContextFactory

    public HtmlUnitContextFactory(WebClient webClient)

    Creates a new instance of HtmlUnitContextFactory.

    Parameters:

    webClient - the web client using this factory

• Method Detail

  • setTimeout

    public void setTimeout(long timeout)

    Sets the number of milliseconds a script is allowed to execute before being terminated. A value of 0 or less means no timeout.

    Parameters:

    timeout - the timeout value

  • getTimeout

    public long getTimeout()

    Returns the number of milliseconds a script is allowed to execute before being terminated. A value of 0 or less means no timeout.

    Returns:

    the timeout value (default value is 0)

  • setDebugger

    public void setDebugger(org.htmlunit.corejs.javascript.debug.Debugger debugger)

    Sets the JavaScript debugger to use to receive JavaScript execution debugging information. The HtmlUnit default implementation (DebuggerImpl, DebugFrameImpl) may be used, or a custom debugger may be used instead. By default, no debugger is used.

    Parameters:

    debugger - the JavaScript debugger to use (may be null)

  • getDebugger

    public org.htmlunit.corejs.javascript.debug.Debugger getDebugger()

    Returns the JavaScript debugger to use to receive JavaScript execution debugging information. By default, no debugger is used, and this method returns null.

    Returns:

    the JavaScript debugger to use to receive JavaScript execution debugging information

  • setDeminifyFunctionCode

    public void setDeminifyFunctionCode(boolean deminify)

    Configures if the code of new Function("...some code...") should be deminified to be more readable when using the debugger. This is a small performance cost.

    Parameters:

    deminify - the new value

  • isDeminifyFunctionCode

    public boolean isDeminifyFunctionCode()

    Indicates code of calls like new Function("...some code...") should be deminified to be more readable when using the debugger.

    Returns:

    the de-minify status

  • preProcess

    protected String preProcess(HtmlPage htmlPage,
     String sourceCode,
     String sourceName,
     int lineNumber,
     HtmlElement htmlElement)

    Pre process the specified source code in the context of the given page using the processor specified in the WebClient. This method delegates to the pre processor handler specified in the WebClient. If no pre processor handler is defined, the original source code is returned unchanged.

    Parameters:

    htmlPage - the page

    sourceCode - the code to process

    sourceName - a name for the chunk of code (used in error messages)

    lineNumber - the line number of the source code

    htmlElement - the HTML element that will act as the context

    Returns:

    the source code after being pre processed

  • makeContext

    protected org.htmlunit.corejs.javascript.Context makeContext()

    Overrides:

    makeContext in class org.htmlunit.corejs.javascript.ContextFactory

  • observeInstructionCount

    protected void observeInstructionCount(org.htmlunit.corejs.javascript.Context cx,
     int instructionCount)

    Run-time calls this when instruction counting is enabled and the counter reaches limit set by setInstructionObserverThreshold(). A script can be terminated by throwing an Error instance here.

    Overrides:

    observeInstructionCount in class org.htmlunit.corejs.javascript.ContextFactory

    Parameters:

    cx - the context calling us

    instructionCount - amount of script instruction executed since last call to observeInstructionCount

  • doTopCall

    protected Object doTopCall(org.htmlunit.corejs.javascript.Callable callable,
     org.htmlunit.corejs.javascript.Context cx,
     org.htmlunit.corejs.javascript.Scriptable scope,
     org.htmlunit.corejs.javascript.Scriptable thisObj,
     Object[] args)

  • callSecured

    public final <T> T callSecured(org.htmlunit.corejs.javascript.ContextAction<T> action,
     HtmlPage page)

    Same as ContextFactory ContextFactory.call(ContextAction) but with handling of some exceptions.

    Type Parameters:

    T - return type of the action

    Parameters:

    action - the contextAction

    page - the page

    Returns:

    the result of the call

  • hasFeature
