Interface QueryResultChange

public interface QueryResultChange

Describes the change of a query result.

Note that the general contract for topologies does not apply here since the topologies from this interface are breakdown fragments. The general contract is:
If a topology A and B are created from the same active query and they have the same query result version, then A's CI and Relation structure is equal to B's structure. Properties are not necessarily equal."

Since:

8.0

Method Summary

Topology	getAddedTopology() Returns the structure containing the elements added to the result of the query.
java.lang.String	getQueryName() The name of the query whose result has changed.
QueryResultVersion	getQueryResultVersion() Returns the query result version after the change.
Topology	getRemovedTopology() Returns the structure containing the elements removed from the result of the query.
Topology	getUpdatedTopology() Returns the structure containing the elements in the query result whose properties were updated.
boolean	hasAddedTopology() Checks whether this elements were added in this change.
boolean	hasRemovedTopology() Returns true if if this change contains removed elements.
boolean	hasUpdatedTopology() Checks whether this elements were updated in this change.
boolean	isMassiveTopologyChange() Checks whether the change is too large to be handled with this mechanism.

Method Detail

getQueryName

java.lang.String getQueryName()

The name of the query whose result has changed.

isMassiveTopologyChange

boolean isMassiveTopologyChange()

Checks whether the change is too large to be handled with this mechanism. If isMassiveTopologyChange returns true, all the has* methods return false. In this case, the application can get the new information by rereading the result of the query.

Returns:

true if a large change has occured

hasAddedTopology

boolean hasAddedTopology()

Checks whether this elements were added in this change.

getAddedTopology

Topology getAddedTopology()

Returns the structure containing the elements added to the result of the query.

hasRemovedTopology

boolean hasRemovedTopology()

Returns true if if this change contains removed elements.

Returns:

true if this change contains removed elements

getRemovedTopology

Topology getRemovedTopology()

Returns the structure containing the elements removed from the result of the query.

hasUpdatedTopology

boolean hasUpdatedTopology()

Checks whether this elements were updated in this change.

getUpdatedTopology

Topology getUpdatedTopology()

Returns the structure containing the elements in the query result whose properties were updated. Only the properties that changed are returned with their CIs and Relations.

getQueryResultVersion

QueryResultVersion getQueryResultVersion()

Returns the query result version after the change. If topology breakdown is available (isMassiveTopologyChange() is false), then for each non-empty topology (Topology.isEmpty() is true), the query result version in that topology is the same as this version.

Returns:

the version of the query result after this change
