Interface TopologyQueryService

public interface TopologyQueryService

Interface for querying the UCMDB topology. To create the data structures used by the methods of this interface, use the factory obtained with the getFactory() method.

Here is an example of executing an ad-hoc query and displaying the results:

 TopologyQueryService queryService = ucmdbService.getTopologyQueryService();
 TopologyQueryFactory queryFactory = queryService.getFactory();
 QueryDefinition queryDefinition = queryFactory.createQueryDefinition("Get hosts with more than one network interface");
 String hostNodeName = "Host";
 QueryNode hostNode = queryDefinition.addNode(hostNodeName).ofType("host").queryProperty("display_label");
 QueryNode ipNode = queryDefinition.addNode("IP").ofType("ip").queryProperty("ip_address");
 hostNode.linkedTo(ipNode).withLinkOfType("contained").atLeast(2);
 Topology topology = queryService.executeQuery(queryDefinition);
 Collection hosts = topology.getCIsByName(hostNodeName);
 for (TopologyCI host : hosts) {
     System.out.println("Host " + host.getPropertyValue("display_label"));
     for (TopologyRelation relation : host.getOutgoingRelations()) {
         System.out.println("  has IP " + relation.getEnd2CI().getPropertyValue("ip_address"));
     }
 }

Method Detail

createQueryStub

Query createQueryStub(java.lang.String queryName)

Creates a Query stub that holds the query name and allows retrieval of the query definition (or reference definition, if applicable).

It is possible to create Query stubs for non-existent queries, but further operations on those stubs will fail.

This method does not communicate with the UCMDB server. However, operations from the stub object do communicate with the server. They fetch the query definition and related information. See Query for details.

createExecutableQuery

ExecutableQuery createExecutableQuery(java.lang.String queryName)

Creates an ExecutableQuery structure. The ExecutableQuery can be used to define customizations over a query execution, such as parameters values, restrictions, seperation to chunks, and so on.

It is possible to create an ExecutableQuery stubs for non-existant queries, but furthur execute operations will fail.

This method does not communicate with the UCMDB server.

Checks the results of each of the given queries in the queryNamesAndVersions and, if they're cached and updated, returns that result (as ids only).

Given a set of queries to check (along with the last result version that the client has), this method will return the ids participating in the updated results. This method is useful in case only the ids are needed, when the expected queries results are relatively small and when these queries results are guaranteed to be in the CMDB result cache - either QueryDefinitionFirstLoadStrategy.LOAD_ON_SERVER_START or active and executed before.

Only updated (or forced) query results are returned. Each of these is returned as an id collection only. In addition, the result version is returned as well - that version should be supplied to a later invocation of this method to allow only the updated results to be returned.

Note: Like all active queries, an updated result may be during to topological change, definition change or properties change. In addition, a false update may occur (rare case) as well.

Parameters:

queryNamesAndVersions - the query names and matching versions to check (or query names to return results for, regardless of versions).

options - an options object - determines the behavior of the service (e.g. are relation ids returned as well?)

Returns:

an object containing the updated queries result (as ids).

hasChanges

@NotFinalAPI
boolean hasChanges(java.lang.String queryName,
                               QueryResultVersion queryResultVersion)

Checks if the results of the query were changed since the result version was created.

This method applies to saved and active queries whose result is still cached in the CMDB memory. In addition to examining the query definition (QueryDefinition.recalcPriority() or QueryReferenceDefinition.recalcPriority()), it is also possible to query the resulting Topology using the Topology.querySupportsHasChanges() method.

This method does not take into account the properties of CIs and Relations that do not participate in the query properties conditions.

Implementation notes:

• If the result is still cached, calling this method also resets the eviction timeout.
• While it's rare, it is possible to get a false positive from this method (true when it should have been false).

Parameters:

queryName - the query to check.

queryResultVersion - the version to check changes from.

Returns:

true if there were any changes in the query results. false if no changes or if the query does not support changes.

hasChanges

@NotFinalAPI
boolean hasChanges(java.lang.String queryName,
                               java.lang.String queryResultVersionAsString)

Same as hasChanges(String, QueryResultVersion), but is passed the result of {QueryResultVersion#asString()}.

Parameters:

queryName - the query to check.

queryResultVersionAsString - the asString() result of the version to check changes from.

Returns:

true if there were any changes in the query results, false if no changes or if the query does not support changes.

hasChanges

@NotFinalAPI
java.util.Set<java.lang.String> hasChanges(java.util.Map<java.lang.String,QueryResultVersion> queries2check)

Same as hasChanges(String, QueryResultVersion), but is passed a collection of queries and their version to check for changes

Parameters:

queries2check - a collection of (query name, query result version) pairs

Returns:

a set of query names, sub set of the given query names, whose result has changed.

retrieveIndirectLinkPaths

@NotFinalAPI
Topology retrieveIndirectLinkPaths(ExecutableQuery executableQuery,
                                               java.util.Set<IndirectLinkDescriptor> indirectLinkDescriptors)

Retrieves the indirect link internal paths for the given descriptors.

Executing a query that contains indirect links without the "show entire path" flag will result in a Topology with "virtual" relations that represents paths of one or more underlying relations. These underlying paths may be retrieved using this method. By supplying the exact same executable query that originated the original topology and a set of request descriptors (source ids, target ids, link node name and, if needed, properties request for the resulting topologies), these underlying paths may be retrieved as a Topology object.

Implementation note: an additional query execution may occur during this request.

Parameters:

executableQuery - the executable query that originated the topology from which the indirect link paths are requried.

indirectLinkDescriptors - the descriptors, created by TopologyQueryFactory.createIndirectLinkDescriptor().

Returns:

the underlying paths topology.

queryDefinitionToString

java.lang.String queryDefinitionToString(QueryDefinition queryDefinition)
                                         throws UcmdbException

Returns the query's string representation.

The conversion from QueryDefinition to string is done in the server, requiring a server request.

This string representation may not be version compatible and should not be serialized for long term storage.

Parameters:

queryDefinition - the query definition to convert to a string

Returns:

String repesentation of the given query definition

Throws:

UcmdbException

stringToQueryDefinition

QueryDefinition stringToQueryDefinition(java.lang.String str)
                                        throws UcmdbException

Returns a copy of the original query definition used to create the string. The input string is created by a call to queryDefinitionToString.

The conversion from string to QueryDefinition is done on the server, requiring a server request.

Parameters:

str - the query's string represntation

Returns:

query definition represnted by the given str

Throws:

UcmdbException

queryReferenceDefinitionToString

java.lang.String queryReferenceDefinitionToString(QueryReferenceDefinition queryReferenceDefinition)

Returns the query refernce's string representation.

The conversion from QueryReferenceDefinition to string is done on the server, requiring a server request.

This string representation may not be version compatible and should not be serialized for long term storage.

Parameters:

queryReferenceDefinition - - the query reference definition to convert

Returns:

String representation of the given query definition

stringToInitializedQuery

Query stringToInitializedQuery(java.lang.String str)

Returns an initialized Query that holds a copy of the original query or query reference definition used to create the string. The input string is created by a call to queryReferenceDefinitionToString or queryDefinitionToString

The conversion is done on the server, requiring a server request.

Note2: Unlike the general contract for Query, the return value from this method does NOT represent a query stored on the CMDB server.

Parameters:

str - - query's string representation

Returns:

an initialized query represented by the given str
