Class QuerySpecificationRegistry

java.lang.Object

org.eclipse.viatra.query.runtime.extensibility.QuerySpecificationRegistry

Deprecated.

Use QuerySpecificationRegistry.getInstance() and read notes on deprecated methods for usage.

public final class QuerySpecificationRegistry
extends java.lang.Object

Registry for query specifications that can be accessed using fully qualified names. In addition, it can create query groups based on the package hierarchy, even if the queries are defined in different projects or query definition files. When running as an OSGi plug-in, the generated query specifications registered through extensions are automatically loaded into the registry by the ExtensionBasedQuerySpecificationLoader class.

Method Detail

registerQuerySpecification

public static void registerQuerySpecification(IQuerySpecification<? extends ViatraQueryMatcher<? extends IPatternMatch>> specification)

Deprecated. Register your own IRegistrySourceConnector through #addSource instead to add and remove specifications.

Puts the specification in the registry, unless it already contains a specification for the given pattern FQN

Parameters:

specification -

unregisterQuerySpecification

public static void unregisterQuerySpecification(java.lang.String patternFQN)

Deprecated. Register your own IRegistrySourceConnector through #addSource instead to add and remove specifications.

Removes the query specification from the registry which belongs to the given fully qualified pattern name. Only dynamically added specifications can be removed! Specifications contributed by extensions cannot be removed. Calling with an FQN that is not dynamically added has no effect.

Parameters:

patternFQN - the fully qualified name of the pattern

getContributedQuerySpecifications

public static java.util.Set<IQuerySpecification<? extends ViatraQueryMatcher<? extends IPatternMatch>>> getContributedQuerySpecifications()

Deprecated. Use getDefaultView().getQueryGroup().getSpecifications() instead

Returns:

the set of contributed query specifications

getQuerySpecification

public static IQuerySpecification<? extends ViatraQueryMatcher<? extends IPatternMatch>> getQuerySpecification(java.lang.String patternFQN)

Deprecated. Use getDefaultView().getEntry(String).get() instead

Parameters:

patternFQN - the fully qualified name of a registered generated pattern

Returns:

the generated query specification of the pattern with the given fully qualified name, if it is registered, or null if there is no such generated pattern

getPatternGroup

public static java.util.Set<IQuerySpecification<? extends ViatraQueryMatcher<? extends IPatternMatch>>> getPatternGroup(java.lang.String packageFQN)

Deprecated. Use new PackageBasedQueryGroup(String packageFQN).getSpecifications() instead

Returns the set of query specifications in a given package. Only query specifications with the exact package fully qualified name are returned.

Parameters:

packageFQN - the fully qualified name of the package

Returns:

the set of query specifications inside the given package, empty set otherwise.

getPatternSubTree

public static java.util.Set<IQuerySpecification<? extends ViatraQueryMatcher<? extends IPatternMatch>>> getPatternSubTree(java.lang.String packageFQN)

Deprecated. Use PackageBasedQueryGroup(String packageFQN, true).getSpecifications() instead

Returns the set of query specifications in a given package. All query specifications with package names starting with the given package are returned.

Parameters:

packageFQN - the fully qualified name of the package

Returns:

the set of query specifications in the given package subtree, empty set otherwise.
