Method Detail

init

public void init()
          throws CoreException

Description copied from interface: ComponentLifecycle

Initialises the component.

Component initialisation includes config verification, creation of connections etc.

Specified by:

init in interface ComponentLifecycle

Throws:

CoreException - wrapping any underlying Exceptions

start

public void start()
           throws CoreException

Description copied from interface: ComponentLifecycle

Starts the component.

Once a component is started it should be ready to process messages. In the case of AdaptrisMessageConsumer, calling start will begin message delivery.

Specified by:

start in interface ComponentLifecycle

Throws:

CoreException - wrapping any underlying Exceptions

stop

public void stop()

Description copied from interface: ComponentLifecycle

Stop the component

A stopped component is not expected to be ready to process messages. In the case of AdaptrisMessageConsumer, calling stop will pause message delivery. Throwing a RuntimeException may cause unintended consequences

Specified by:

stop in interface ComponentLifecycle

close

public void close()

Description copied from interface: ComponentLifecycle

Closes the component.

A closed component should release any connections it uses, etc. and clean up completely. Throwing a RuntimeException may cause unintended consequences

Specified by:

close in interface ComponentLifecycle

evaluate

public boolean evaluate(AdaptrisMessage msg)
                 throws CoreException

Specified by:

evaluate in interface Condition

Throws:

CoreException

getConnection

public AdaptrisConnection getConnection()

setConnection

public void setConnection(AdaptrisConnection connection)

Set the connection to the Cache instance.

Parameters:

connection - the connection.

getKey

public java.lang.String getKey()

setKey

public void setKey(java.lang.String key)

Specify the key to check for in the cache.

Parameters:

key - the key.

withConnection

public ExistsInCache withConnection(AdaptrisConnection c)

withKey

public ExistsInCache withKey(java.lang.String key)
