Method Detail

generates

Class[] generates()

Returns the class of objects that it generates.

Returns:

the Class of the generated tokens

output

Token output()

Returns the generated token.

Returns:

the generated token

hasPendingOutput

boolean hasPendingOutput()

Checks whether there is pending output to be collected after executing the flow item.

The method is not allowed allowed to return "true" before the actor has been executed. For actors that return an infinite number of tokens, the m_Executed flag can be returned.

Returns:

true if there is pending output
