Method Detail

pre

public void pre()

Description copied from interface: SUL

setup SUL.

Specified by:

pre in interface SUL<I,O>

post

public void post()

Description copied from interface: SUL

shut down SUL.

Specified by:

post in interface SUL<I,O>

step

@Nullable
public O step(@Nullable
                        I in)
                 throws SULException

Description copied from interface: SUL

make one step on the SUL.

Specified by:

step in interface SUL<I,O>

Parameters:

in - input to the SUL

Returns:

output of SUL

Throws:

SULException

getStatisticalData

@Nonnull
public Counter getStatisticalData()

Specified by:

getStatisticalData in interface StatisticSUL<I,O>

canFork

public boolean canFork()

Description copied from interface: SUL

Returns whether this SUL is capable of forking.

Specified by:

canFork in interface SUL<I,O>

Returns:

true if this SUL can be forked, false otherwise

SUL.fork()

fork

public SUL<I,O> fork()

Description copied from interface: SUL

Forks this SUL, if possible. The fork of a SUL is a copy which behaves exactly the same as this SUL. This method should always return a reseted SUL, regardless of whether this call is made between a call to SUL.pre() and SUL.post().

If SUL.canFork() returns true, this method must return a non-null object, which should behave exactly like this SUL (in particular, it must be forkable as well). Otherwise, a UnsupportedOperationException must be thrown.

Implementation note: if resetting a SUL changes the internal state of this object in a non-trivial way (e.g., incrementing a counter to ensure independent sessions), care must be taken that forks of this SUL manipulate the same internal state.

Specified by:

fork in interface SUL<I,O>

Returns:

a fork of this SUL.
