execute

public R execute(T input,
                 ExecCtx ctx)
          throws Exception

Description copied from interface: IFunction

Executes the function on the current target object, which is passed as the input parameter. The ExecCtx parameter provides some metadata related to the execution, like the index in an iteration.

The execution of a function can throw any exception.

If you intend to call the execute method directly on any of your functions (outside an op4j expression), you might prefer using Function.execute(Object) instead.

Parameters:

input - the target object on which the function is to be executed

ctx - the context (metadata) for the function execution

Returns:

the result of executing the function

Throws:

Exception
