Method Detail

close

void close()

Specified by:

close in interface AutoCloseable

shut

void shut()

query

<RESULT> RESULT query(Query<IMMUTABLE,RESULT> query)

Query system (immutable view of it). Few things to remember: 1. if operations done on system (using query) do make some changes they will not be preserved (for long) 2. it is possible to return any object from domain (including IMMUTABLE root) and perform operations later on (but the more You do inside Query the safer).

Type Parameters:

RESULT - result of query

Parameters:

query - lambda (or query implementation) with operations

Returns:

calculated result

executeAndQuery

<R> R executeAndQuery(ContextCommand<T,R> cmd)

Perform command on system. Inside command can be any code doing any changes. Such changes are guaranteed to be preserved (if only command ended without exception).

Parameters:

cmd -

executeAndQuery

<R> R executeAndQuery(Command<T,R> cmd)

Perform command on system. Inside command can be any code doing any changes. Such changes are guaranteed to be preserved (if only command ended without exception).

Parameters:

cmd -

execute

void execute(VoidCommand<T> cmd)

execute

void execute(VoidContextCommand<T> cmd)

isOpen

boolean isOpen()
