Method Detail

setServiceBeanContext

public void setServiceBeanContext(ServiceBeanContext context)

setupDrools

@Initialized
public void setupDrools()

getScannerInterval

public int getScannerInterval()

Description copied from interface: Gnostic

Get the amount of time (in seconds) the Gnostic polls for changes to managed rules.

Specified by:

getScannerInterval in interface Gnostic

Returns:

The amount of time (in seconds) the Gnostic polls for changes made to managed rules

setScannerInterval

public void setScannerInterval(int interval)

Description copied from interface: Gnostic

Set the amount of time (in seconds) the Gnostic polls for changes to managed rules.

Specified by:

setScannerInterval in interface Gnostic

Parameters:

interval - The amount of time (in seconds) to poll

add

public boolean add(RuleMap ruleMap)

Description copied from interface: Gnostic

Add a rule mapping to Gnostic.

Specified by:

add in interface Gnostic

Parameters:

ruleMap - The rule mapping to add.

Returns:

True if the rule mapping was added, false otherwise. If the rule mapping already exists, this method will return false. Note that adding a rule mapping is asynchronous. Returning true means that the rule was added for processing. The rule(s) still require compilation and validation, verifying that the rule has been added can be achieved by getting the managed rule mappings.

remove

public boolean remove(RuleMap ruleMap)

Description copied from interface: Gnostic

Remove an existing managed rule mapping

Specified by:

remove in interface Gnostic

Parameters:

ruleMap - The rule map to remove

Returns:

True if the rule mapping was removed, false otherwise. If the rule mapping does not exist, this method will return false.

get

public List<RuleMap> get()

Description copied from interface: Gnostic

Get all managed rule mappings

Specified by:

get in interface Gnostic

Returns:

A non-modifiable list of managed rule mappings. If there are no managed rule mappings a zer-length array is returned. A new array is created each time.

cleanup

@PreDestroy
public void cleanup()
