Method Detail

init

public void init()

Initialize the rule system. The rule system needs to be initialized once, before rules can be fired. When trying to initialize the rule system twice, an exception is thrown. Exceptions are also thrown, when trying to fire rules of a not yet initialized rule system

isInited

public boolean isInited()

Get the inited.

Returns:

the inited.

getState

public IOAVState getState()

Get the memory.

Returns:

The memory.

getRulebase

public IRulebase getRulebase()

Get the rulebase.

Returns:

The rulebase.

getAgenda

public IAgenda getAgenda()

Get the agenda. The agenda can only be accessed, after the rule system has been initialized with init().

Returns:

The agenda.

fireAllRules

public void fireAllRules()

Fire all rules until quiescence.

getMatcherFunctionality

public IPatternMatcherFunctionality getMatcherFunctionality()

Get the matcher functionality.

Returns:
