Interface WritableDatabase

All Known Implementing Classes:

Database, RDBMSDatabase

public interface WritableDatabase

A database for persisting GroundAtoms. To retrieve GroundAtoms use a ReadableDatabase.

Method Summary

Modifier and Type	Method and Description
void	close() Releases the Partitions used by this Database.
void	commit(Collection<RandomVariableAtom> atoms) A batch form or commit().
void	commit(Collection<RandomVariableAtom> atoms, int partitionId) A form of commit() that allows the caller to choose the specific partition the atoms are comitted to.
void	commit(RandomVariableAtom atom) Persists a RandomVariableAtom in this Database's write Partition.
boolean	deleteAtom(GroundAtom a) Removes the GroundAtom from the Database, if it exists.
void	moveToWritePartition(StandardPredicate predicate, int oldPartitionId) Move all ground atoms of a predicate/partition combination into the write partition.

Method Detail

deleteAtom

boolean deleteAtom(GroundAtom a)

Removes the GroundAtom from the Database, if it exists.

commit

void commit(RandomVariableAtom atom)

Persists a RandomVariableAtom in this Database's write Partition. If the RandomVariableAtom has already been persisted in the write Partition, it will be updated.

commit

void commit(Collection<RandomVariableAtom> atoms)

A batch form or commit(). When possible, this commit should be used.

commit

void commit(Collection<RandomVariableAtom> atoms,
            int partitionId)

A form of commit() that allows the caller to choose the specific partition the atoms are comitted to. Should only be used if you REALLY know what you are doing.

moveToWritePartition

void moveToWritePartition(StandardPredicate predicate,
                          int oldPartitionId)

Move all ground atoms of a predicate/partition combination into the write partition. Be careful not to call this while the database is in use.

close

void close()

Releases the Partitions used by this Database.
