All Implemented Interfaces:

PoolableObjectFactory

public class BLMContextFactory

extends BasePoolableObjectFactory

Implements PoolableObjectFactory for managing BLMContextManager instances. The validateObject(Object) method assures that the instances in the pool are periodically destroyed. The factory also allows to plug-in an additional BLMContextManager validator.

BLMContextFactory

public BLMContextFactory(java.lang.String blmURL,
                         BLMAdminSubjectIdentityAssertionTokenType token,
                         BLMContextValidator validator,
                         long maxContextLifeTime)

Parameters:

blmURL -

token -

validator -

maxContextLifeTime - Context lifetime in seconds

BLMContextFactory

public BLMContextFactory(java.lang.String url,
                         java.lang.String username,
                         java.lang.String password)

Same as BLMContextFactory(url, username, password, null, 5). Creates a BLMContextFactory object with no additional validator and maximum duration of context lives equal to five minutes.

Parameters:

url - BLM server URL

username - BLM user's name

password - password that corresponds to username

BLMContextFactory

public BLMContextFactory(java.lang.String url,
                         java.lang.String username,
                         java.lang.String password,
                         BLMContextValidator blmContextValidator,
                         long maxContextLifeTime)

Creates an instance of BLMContextFactory

Parameters:

url - BLM server URL

username - BLM user's name

password - password that corresponds to username

blmContextValidator - optional BLMContextValidator that is called when an instance of BLMContextManager is validated. E.g., you can implement a BLMContextValidator based on calling some 'inexpensive' BLM method. The value can be null. In that case, no additional validation will take place.

maxContextLifeTime - maximum time in minutes the context should live before it is destroyed. Only the contexts in the pool are destroyed and not the ones that are borrowed. If value is 0, the object will never be destroyed.
