Method Details

execute

public final Object execute(com.oracle.truffle.api.frame.VirtualFrame frame)

Description copied from class: JavaScriptNode

Executes this node using the specified context and frame and returns the result value.

Specified by:

execute in class JavaScriptNode

Parameters:

frame - the frame of the currently executing guest language method

Returns:

the value of the execution

executeBoolean

public abstract boolean executeBoolean(com.oracle.truffle.api.frame.VirtualFrame frame)

Description copied from class: JavaScriptNode

Like JavaScriptNode.execute(VirtualFrame) except that it tries to convert the result value to a boolean. A node can override this method if it has a better way to producing a value of type boolean.

Overrides:

executeBoolean in class JavaScriptNode

Parameters:

frame - the frame of the currently executing guest language method

Returns:

the value of the execution as a boolean

isResultAlwaysOfType

public final boolean isResultAlwaysOfType(Class<?> clazz)

Overrides:

isResultAlwaysOfType in class JavaScriptNode
