unbindNetworkTargetFromIdentity(Object) - Method in class org.hypergraphdb.peer.HyperGraphPeer

unfreeze(HGLiveHandle) - Method in class org.hypergraphdb.cache.DefaultAtomCache

unfreeze(HGLiveHandle) - Method in class org.hypergraphdb.cache.WeakRefAtomCache

unfreeze(HGLiveHandle) - Method in interface org.hypergraphdb.HGAtomCache

Unfreezing a previously frozen atom makes it available for eviction.

unfreeze(HGHandle) - Method in class org.hypergraphdb.HyperGraph

Unfreeze a previously frozen atom so that it becomes subject of eviction from the cache.

UnionQuery - Class in org.hypergraphdb.query.impl

An UnionQuery combines the results of two underlying queries and produces a result set containing elements that appear in either of the input result sets.

UnionQuery(HGQuery, HGQuery) - Constructor for class org.hypergraphdb.query.impl.UnionQuery

Construct a union of two queries.

UnionResult - Class in org.hypergraphdb.query.impl

Combines two result set into a result representing their set theoretic union.

UnionResult(HGSearchResult, HGSearchResult) - Constructor for class org.hypergraphdb.query.impl.UnionResult

unregister(HGIndexer) - Method in class org.hypergraphdb.HGIndexManager

Remove an existing index.

unregisterAll(HGHandle) - Method in class org.hypergraphdb.HGIndexManager

Remove all indexers for the given type.

update(Object) - Method in class org.hypergraphdb.HyperGraph

Update the value of an atom in HyperGraph.

updateNetworkProperties() - Method in class org.hypergraphdb.peer.HyperGraphPeer

will broadcast messages and update the peers knowledge of the neighboring peers

updateSubgraph(Subgraph) - Method in class org.hypergraphdb.peer.StorageService

UUID - Class in org.hypergraphdb.handle

NOTE - code adapted from JUG libary (Copyright (c) 2002- Tatu Saloranta, tatu.saloranta@iki.fi).

UUID() - Constructor for class org.hypergraphdb.handle.UUID

Default constructor creates a NIL UUID, one that contains all zeroes Note that the clearing of array is actually unnecessary as JVMs are required to clear up the allocated arrays by default.

UUID(byte[]) - Constructor for class org.hypergraphdb.handle.UUID

Constructor for cases where you already have the 16-byte binary representation of the UUID (for example if you save UUIDs binary takes less than half of space string representation takes).

UUID(byte[], int) - Constructor for class org.hypergraphdb.handle.UUID

Constructor for cases where you already have the binary representation of the UUID (for example if you save UUIDs binary takes less than half of space string representation takes) in a byte array

UUID(String) - Constructor for class org.hypergraphdb.handle.UUID

Constructor for creating UUIDs from the canonical string representation Note that implementation is optimized for speed, not necessarily code clarity...

UUID_NULL_HANDLE - Static variable in class org.hypergraphdb.handle.UUIDPersistentHandle

UUIDPersistentHandle - Class in org.hypergraphdb.handle

UUIDPersistentHandle() - Constructor for class org.hypergraphdb.handle.UUIDPersistentHandle

Default constructor create a new UUID.

UUIDTrie - Class in org.hypergraphdb.atom.impl

An implementation of a trie for storing UUIDs.

UUIDTrie() - Constructor for class org.hypergraphdb.atom.impl.UUIDTrie
