Detailed Description

A basic history implementation. Keeps a history (and forward) stack of state objects of type T. exposes current state and availability of advance/retreat operations via methods and JFX Property objects. Null is not a valid state, and will only be the current state before the first call to advance.

Parameters

T	the type of objects used to represent the current/historical/future states

Member Function Documentation

synchronized T org.sleuthkit.autopsy.coreutils.History< T >.advance

(

)

advance through the forward states by one, and put the current state in the history. Is a no-op if there are no forward states.

Returns

the state advanced to, or null if there were no forward states.

Definition at line 107 of file History.java.

synchronized void org.sleuthkit.autopsy.coreutils.History< T >.advance

(

T

newState

)

throws IllegalArgumentException

put the current state in the history and advance to the given state. It is a no-op if the current state is equal to the given state as determined by invoking the equals method. Throws away any forward states.

Parameters

newState

the new state to advance to

Exceptions

IllegalArgumentException

if newState == null
