Interface ControlCommand

All Known Implementing Classes:
  ElseCommand, EndifCommand, IfCommand, LoopCommand, ExitloopCommand, EndloopCommand

public abstract interface ControlCommand
extends Command

This interface is used to supply implementations of SSI commands. They have to be registered in a CommandRegistry, which in turn is used by the SSIFrame. A control command is a command like loop or if witch can modify the way to execute commands. A control command have to register is position and to know the next position. A position is an integer, witch can be an array index.

Method Summary
`int` | `jumpTo(SSIFrame ssiframe, Request request, CommandRegistry registry, ArrayDictionary parameters, java.util.Dictionary variables)` Give the next position in the structure witch store the SSIFrame.
`void` | `setPosition(SSIFrame ssiframe, Request request, CommandRegistry registry, ArrayDictionary parameters, java.util.Dictionary variables, int position)` register the command position in the structure witch store the SSIFrame.
