Class BaseSingleValueIndexStore

java.lang.Object

com.hazelcast.query.impl.BaseIndexStore

com.hazelcast.query.impl.BaseSingleValueIndexStore

All Implemented Interfaces:

IndexStore

Direct Known Subclasses:

OrderedIndexStore, UnorderedIndexStore

public abstract class BaseSingleValueIndexStore
extends BaseIndexStore

The base store for indexes that are unable to work with multi-value attributes natively. For such indexes MultiResults are split into individual values and each value is inserted/removed separately.

Method Summary

Modifier and Type	Method and Description
void	destroy() Destroys this index by releasing all its resources.
void	insert(Object value, QueryableEntry record, IndexOperationStats operationStats) Inserts the given entry into this index store under the given value acting as an index key.
void	remove(Object value, Data entryKey, Object entryValue, IndexOperationStats operationStats) Removes the existing entry mapping in this index.
void	update(Object oldValue, Object newValue, QueryableEntry entry, IndexOperationStats operationStats) Updates the existing entry mapping in this index by remapping it from the given old value to the new given value.

Method Detail

insert

public final void insert(Object value,
                         QueryableEntry record,
                         IndexOperationStats operationStats)

Description copied from interface: IndexStore

Inserts the given entry into this index store under the given value acting as an index key.

Parameters:

value - the value to insert the entry under.

record - the entry to insert.

operationStats - the operation stats to update while performing the operation.

update

public final void update(Object oldValue,
                         Object newValue,
                         QueryableEntry entry,
                         IndexOperationStats operationStats)

Description copied from interface: IndexStore

Updates the existing entry mapping in this index by remapping it from the given old value to the new given value.

The update operation is logically equivalent to removing the old mapping and inserting the new one.

Parameters:

oldValue - the value to remap the entry from.

newValue - the new value to remap the entry to.

entry - the entry to remap.

operationStats - the operation stats to update while performing the operation.

remove

public final void remove(Object value,
                         Data entryKey,
                         Object entryValue,
                         IndexOperationStats operationStats)

Description copied from interface: IndexStore

Removes the existing entry mapping in this index.

Parameters:

value - the value to remove the mapping from.

entryKey - the entry key to remove the mapping to.

entryValue - the entry value to remove the mapping to.

operationStats - the operation stats to update while performing the operation.
