ActiveSpaces Palette

A palette groups the activities that connect the same external applications together. An ActiveSpaces palette is added after installing TIBCO ActiveMatrix BusinessWorks Plug-in for ActiveSpaces.

The ActiveSpaces palette contains the following activities:

• Basic operation activities are as follows:
  • Put
  • Get
  • Take
• Transaction activities are as follows:
  • BeginTransaction
  • CommitTransaction
  • RollbackTransaction
• Browser activities are as follows:
  • ContinuousQuery
  • EventListener
• Query activities are as follows:
  • Query
  • QueryIterator
  • QueryDynamic
• Wait and Lock activities are as follows:
  • WaitForReady
  • Lock
  • UnLock
• Invoke activities are as follows:
  • RemoteInvoke
  • InvocableReceiver
  • InvocableResponse
• SpaceResultHandler activity
• Persister activities are as follows:
  • PersisterReceiver
  • PersisterResponse
• Space activities are as follows:
  • SpaceSize
  • SpaceClear

• Put
  The Put activity is used to store tuples in a space.
• Get
  The Get activity is used to query tuples from a space.
• Take
  The Take activity is used to retrieve and remove tuples from a space.
• BeginTransaction
  The BeginTransaction activity is used to start a transaction in an ActiveSpaces process.
• CommitTransaction
  The CommitTransaction activity is used to commit all of the space operations that are invoked after the BeginTransaction activity was called.
• RollbackTransaction
  The RollbackTransaction activity is used to revert all of the space operations that are invoked after the BeginTransaction activity was called.
• ContinuousQuery
  The ContinuousQuery activity is used to iterate through the contents of a space.
• EventListener
  The EventListener activity is a process starter that creates a process instance for incoming events in a specified space. It can listen for the Put, Take, Expire, Seed, and Unseed events, which occur in the specified space.
• Query
  The Query activity is used to retrieve the entries that match the conditions you specified in the associated space.
• QueryDynamic
  The QueryDynamic activity is used to retrieve entries with parameters. The parameters can be outputs of a process.
• QueryIterator
  The QueryIterator activity is used to retrieve one or more tuples at a time. This activity is usually used in a TIBCO BusinessWorks group.
• WaitForReady
  The WaitForReady activity is used to suspend a process until the space reaches the READY state.
• Lock
  The Lock activity is used to make a key in a space read-only. When a key is locked, only the lock owner can modify the data that is stored with that key.
• UnLock
  The UnLock activity is used to clear the lock on the tuple with a specified key. Only the thread that locked the tuple can clear the lock on the tuple.
• RemoteInvoke
  The RemoteInvoke activity is used to remotely invoke other members in a space.
• InvocableReceiver
  The InvocableReceiver activity is used to receive invocation requests from the RemoteInvoke activity.
• InvocableResponse
  The InvocableResponse activity is used to respond to the InvocableReceiver activity with invocation results.
• SpaceResultHandler
  The SpaceResultHandler activity is used to perform asynchronous operations.
• PersisterReceiver
  The PersisterReceiver activity is used to start the persister and monitor the persister events.
• PersisterResponse
  The PersisterResponse activity is used to respond to the PersisterReceiver activity with invocation results.
• SpaceSize
  The SpaceSize activity is used to count the number of tuples.
• SpaceClear
  The SpaceClear activity is used to delete tuples in a space.
