Class ManualStoreStrategy

java.lang.Object

org.apache.jena.mem.store.strategies.ManualStoreStrategy

All Implemented Interfaces:

StoreStrategy

public class ManualStoreStrategy
extends Object
implements StoreStrategy

StoreStrategy that never builds an index automatically. Add/remove/clear are no-ops on the index side; pattern-match operations throw UnsupportedOperationException until the user explicitly initializes the index (typically via GraphMemIndexedSet.initializeIndex() or GraphMemIndexedSet.initializeIndexParallel()), which swaps this strategy out for an IndexingStrategy.EAGER strategy.

Used to back IndexingStrategy.MANUAL.

Method Details

addToIndex

public void addToIndex(Triple triple,
 int index)

Description copied from interface: StoreStrategy

Notify the strategy that a triple was added to the underlying triple set at the given index. Implementations that maintain an index must update it; implementations without an index are free to no-op.

Specified by:

addToIndex in interface StoreStrategy

Parameters:

triple - the newly added triple

index - the stable index it now occupies in the triple set

removeFromIndex

public void removeFromIndex(Triple triple,
 int index)

Description copied from interface: StoreStrategy

Notify the strategy that the triple at the given index has been removed from the underlying triple set. Implementations that maintain an index must remove the triple from it; implementations without an index are free to no-op.

Specified by:

removeFromIndex in interface StoreStrategy

Parameters:

triple - the removed triple

index - the index it occupied immediately before removal

clearIndex

public void clearIndex()

Description copied from interface: StoreStrategy

Discard any auxiliary index data held by the strategy. Implementations without an index may no-op.

Specified by:

clearIndex in interface StoreStrategy
