Methods

Modifier and Type	Method and Description
void	constraintDrop(Statement state, UniquenessConstraint constraint)
org.neo4j.kernel.impl.api.index.IndexDescriptor	indexCreate(Statement state, long labelId, long propertyKeyId) Creates an index, indexing properties with the given propertyKeyId for nodes with the given labelId.
void	indexDrop(Statement state, org.neo4j.kernel.impl.api.index.IndexDescriptor descriptor) Drops a IndexDescriptor from the database
void	uniqueIndexDrop(Statement state, org.neo4j.kernel.impl.api.index.IndexDescriptor descriptor) This should not be used, it is exposed to allow an external job to clean up constraint indexes.

Method Detail

indexCreate

org.neo4j.kernel.impl.api.index.IndexDescriptor indexCreate(Statement state,
                                                          long labelId,
                                                          long propertyKeyId)
                                                            throws AddIndexFailureException,
                                                                   AlreadyIndexedException,
                                                                   AlreadyConstrainedException

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

Throws:

AddIndexFailureException

AlreadyIndexedException

AlreadyConstrainedException

indexDrop

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

Drops a IndexDescriptor from the database

Throws:

DropIndexFailureException

uniqueIndexDrop

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

This should not be used, it is exposed to allow an external job to clean up constraint indexes. That external job should become an internal job, at which point this operation should go away.

Throws:

DropIndexFailureException

uniquenessConstraintCreate

UniquenessConstraint uniquenessConstraintCreate(Statement state,
                                              long labelId,
                                              long propertyKeyId)
                                                throws AlreadyConstrainedException,
                                                       CreateConstraintFailureException,
                                                       AlreadyIndexedException

Throws:

AlreadyConstrainedException

CreateConstraintFailureException

AlreadyIndexedException

constraintDrop

void constraintDrop(Statement state,
                  UniquenessConstraint constraint)
                    throws DropConstraintFailureException

Throws:

DropConstraintFailureException
