ping

public void ping()
          throws PushAPIException

Description copied from class: PushAPI

Tests the connection with the server. This test should be called after the construction of the Push API. The purpose of this method is to:

• test the server availability
• check for the existence of the connectorName and its security
• compare the PAPI protocol versions

Specified by:

ping in class PushAPI

Throws:

PushAPIException - upon error (invalid connector name or IO error)

setCheckpoint

public java.math.BigInteger setCheckpoint(java.lang.String value,
                                          java.lang.String name,
                                          boolean sync)
                                   throws PushAPIException

Description copied from class: PushAPI

Sets a checkpoint in the push server. Checkpoints are used when:

• The connector must process a journalized or logged data source, which can be abstractly represented as a flow of "add" and "delete" events in the corpus and where an id can be used to refer to events on a timeline. The Connector will then call from time to time the setCheckpoint command with the id referring to the last add or delete events which have been sent to the push server.
• Crash-proof synchronization is required. Upon crash, or system restart, the Connector will call the getCheckpoint method to retrieve the last checkpoint saved by the push server. It is guaranteed that any add or delete commands called before that checkpoint were saved and will never be lost.
• In order to keep track of the synchronization.

If the checkpoint already exists, it's value is replaced with the new value.

Note that on the server side, checkpoints are not automatically synchronized on disk, unless you set the value of the sync attribute to true. This means that a getCheckpoint operation called immediately after a setCheckpoint operation might not return the last value set. Refer to the EXALEAD CloudView documentation for more information on the handling of indexing tasks by the push server.

The setCheckpoint operation returns the serial of the last pending operation before the checkpoint which can be used to check when the documents sent prior this checkpoint can be searched. See PushAPI.areDocumentsSearchable(BigInteger) for more information.

Specified by:

setCheckpoint in class PushAPI

Parameters:

value - the value of the checkpoint.

name - the name of the checkpoint.

sync - if all the pending operations in the task log should be synchronized to disk before returning.

Returns:

the serial of the last pending operation before the checkpoint.

Throws:

PushAPIException - upon error

sync

@Deprecated
public void sync()
                      throws PushAPIException

Deprecated. since V6R2015x, replaced by synchronize()

Description copied from class: PushAPI

Forces the synchronization of all pending operations before returning.

Every operation sent to the push server is kept in a tasks log. These tasks are not automatically synchronized to disk as the synchronization operation requires the use of IO operations which can consume some time. Thus, the synchronization is done asynchronously. This method can be used to force the tasks log synchronization. Refer to the EXALEAD CloudView documentation for more information on the tasks log and related components.

Since V6R2015x, PushAPI.synchronize() has been introduced and returns a serial.

Specified by:

sync in class PushAPI

Throws:

PushAPIException - upon error

triggerIndexingJob

public void triggerIndexingJob()
                        throws PushAPIException

Description copied from class: PushAPI

Forces the processing of all pending operations synchronized to disk. Indexing operations are processed asynchronously, using a batch of operations found in the task logs. An internal scheduler periodically triggers indexing operations but you can also use this API call to force the indexing. Refer to EXALEAD CloudView documentation for more information on the scheduling of indexing jobs.

Note that this call only impacts operation which are already synchronized to disk. Synchronization to disk happens periodically, and it can also be forced by using the setCheckpoint call with the sync parameter or by using the sync call.

Specified by:

triggerIndexingJob in class PushAPI

Throws:

PushAPIException - upon error

triggerIndexingJobWhenIdle

public void triggerIndexingJobWhenIdle()
                                throws PushAPIException

Description copied from class: PushAPI

Wait for indexing to be idle, and forces the processing of all pending operations synchronized to disk. Indexing operations are processed asynchronously, using a batch of operations found in the task logs. An internal scheduler periodically triggers indexing operations but you can also use this API call to force the indexing. Refer to Exalead CloudView documentation for more information on the scheduling of indexing jobs.

Description copied from class: PushAPI

Partially updates a document. This method updates a document which must have the same URI as the one to be updated. Note that the fields parameter is useless for the moment, it is not handled yet. This methods also updates the indexed document stamp.

Specified by:

updateDocument in class PushAPI

Parameters:

doc - a Document object specifying the URI of the document to be updated. Parts and metas that are not updated with the document are fetched from the document cache, so the document cache *must* be enabled, and only documents added after the document cache has been enabled can be updated. Old values of multivalued metas will be dropped, if you want to update a multivalued meta you have to put new values and also the old values you want to keep in the document.

fields - Not used for the moment.

Throws:

PushAPIException

                                     throws PushAPIException

Deprecated.

Description copied from class: PushAPI

Updates the stamp and the meta data of a document, using a strict meta to field mapping. Usage of this method is not recommended. This method should be used with caution. It's actually a simple wrapper on top of the method PushAPI.updateDocument(Document, String[]) which automatically creates the list of index fields from the meta names found in the meta data container.
This method will often not do what you want, because of internal remapping between metas and fields. If you use this method to update the meta "meta1", but it's actually sent to an index field document_meta1 (as it's often the case with the data model), the update will not work as expected. If we reuse the sample described in the comments of the method PushAPI.updateDocument(Document, String[]), this gives:
MetaContainer cont = new MetaContainer();
cont.addMeta("organization", "myneworg");
papi.updateDocument("mydocument", null, cont);


If the document does not exist yet, an error is returned by the push server.

Specified by:

updateDocumentMetas in class PushAPI

Parameters:

uri - the URI of the document to update

stamp - the new document stamp

metaContainer - the container of meta to be updated

Throws:

PushAPIException - upon error

Deprecated.

Description copied from class: PushAPI

Updates a set of the stamp and meta data for given documents. Usage of this method is not recommended. This method should be used with caution. It's actually a simple wrapper on top of the method PushAPI.updateDocument(Document, String[]) which automatically creates the list of index fields from the meta names found in the meta data container.
This method will often not do what you want, because of internal remapping between metas and fields. If you use this method to update the meta "meta1", but it's actually sent to an index field document_meta1 (as it's often the case with the data model), the update will not work as expected. If one of the documents does not exist, an error is returned by the push server. As the update document commands are processed sequentially, all the updates priori to the one which failed are taken into account. However, consider it is require to send again the whole set of documents once the document in error has been removed from the list.

Specified by:

updateDocumentMetasList in class PushAPI

Parameters:

uriList - the URIs of the documents to update

stampList - the list of new stamps

metaContainerList - the list of meta data containers

Throws:

PushAPIException - upon error
