Method Detail

indexCreate

org.neo4j.kernel.impl.api.index.IndexDescriptor indexCreate(long labelId,
                                                          long propertyKeyId)
                                                            throws SchemaKernelException

Creates an index, indexing properties with the given propertyKeyId for nodes with the given labelId.

Throws:

SchemaKernelException

uniqueIndexCreate

org.neo4j.kernel.impl.api.index.IndexDescriptor uniqueIndexCreate(long labelId,
                                                                long propertyKey)
                                                                  throws SchemaKernelException

Creates an index for use with a uniqueness constraint. The index indexes properties with the given propertyKeyId for nodes with the given labelId, and assumes that the database provides it with unique property values. If unique property values are not provided by the database, the index will notify through an exception and enter a "bad state". (This notification facility is used during the verification phase of uniqueness constraint creation). This method is not used from the outside. It is used internally when creating a uniqueness constraint, invoked through a separate transaction (the separate transaction is why it has to be exposed in this API).

Throws:

SchemaKernelException

indexDrop

void indexDrop(org.neo4j.kernel.impl.api.index.IndexDescriptor descriptor)
               throws DropIndexFailureException

Drops a IndexDescriptor from the database

Throws:

DropIndexFailureException

uniqueIndexDrop

void uniqueIndexDrop(org.neo4j.kernel.impl.api.index.IndexDescriptor descriptor)
                     throws DropIndexFailureException

Throws:

DropIndexFailureException

uniquenessConstraintCreate

UniquenessConstraint uniquenessConstraintCreate(long labelId,
                                              long propertyKeyId)
                                                throws SchemaKernelException,
                                                       org.neo4j.kernel.impl.api.ConstraintCreationKernelException

Throws:

SchemaKernelException

org.neo4j.kernel.impl.api.ConstraintCreationKernelException

constraintDrop

void constraintDrop(UniquenessConstraint constraint)
