Method Detail

setGlobalAssociation

public static final <M> void setGlobalAssociation(MultiResult result,
                                                  AssociationID<M> meta,
                                                  M value)

Set global meta association. It tries to replace an existing Association first, then tries to insert in the first MetadataResult otherwise creating a new MetadataResult if none was found.

Type Parameters:

M - restriction class

Parameters:

result - Result collection

meta - Association

value - Value

getGlobalAssociation

public static final <M> M getGlobalAssociation(Result result,
                                               AssociationID<M> meta)

Get first Association from a MultiResult.

Type Parameters:

M - restriction class

Parameters:

result - Result collection

meta - Association

Returns:

first match or null

findAnnotationResult

public static final <T> AnnotationResult<T> findAnnotationResult(Result result,
                                                                 AssociationID<T> assoc)

(Try to) find an association of the given ID in the result.

Type Parameters:

T - Association result type

Parameters:

result - Result to find associations in

assoc - Association

Returns:

First matching annotation result or null

findAnnotationResult

public static final <T> AnnotationResult<T> findAnnotationResult(List<AnnotationResult<?>> anns,
                                                                 AssociationID<T> assoc)

(Try to) find an association of the given ID in the result.

Type Parameters:

T - Association result type

Parameters:

anns - List of Results

assoc - Association

Returns:

First matching annotation result or null

getAnnotationResults

public static List<AnnotationResult<?>> getAnnotationResults(Result r)

Collect all Annotation results from a Result

Parameters:

r - Result

Returns:

List of all annotation results

getOrderingResults

public static List<OrderingResult> getOrderingResults(Result r)

Collect all ordering results from a Result

Parameters:

r - Result

Returns:

List of ordering results

getClusteringResults

public static List<Clustering<?>> getClusteringResults(Result r)

Collect all clustering results from a Result

Parameters:

r - Result

Returns:

List of clustering results

getIterableResults

public static List<IterableResult<?>> getIterableResults(Result r)

Return all Iterable results

Parameters:

r - Result

Returns:

List of iterable results

getMetadataResults

public static List<MetadataResult> getMetadataResults(Result r)

Return all Metadata results

Parameters:
