Returns the index rule for the given labelId and propertyKey.

Throws:

SchemaRuleNotFoundException

indexesGetForLabel

Iterator<org.neo4j.kernel.impl.api.index.IndexDescriptor> indexesGetForLabel(long labelId)

Get all indexes for a label.

indexesGetAll

Iterator<org.neo4j.kernel.impl.api.index.IndexDescriptor> indexesGetAll()

Returns all indexes.

uniqueIndexesGetForLabel

Iterator<org.neo4j.kernel.impl.api.index.IndexDescriptor> uniqueIndexesGetForLabel(long labelId)

Get all constraint indexes for a label.

uniqueIndexesGetAll

Iterator<org.neo4j.kernel.impl.api.index.IndexDescriptor> uniqueIndexesGetAll()

Returns all constraint indexes.

indexGetState

InternalIndexState indexGetState(org.neo4j.kernel.impl.api.index.IndexDescriptor descriptor)
                                 throws IndexNotFoundKernelException

constraintsGetForLabelAndPropertyKey

Iterator<UniquenessConstraint> constraintsGetForLabelAndPropertyKey(long labelId,
                                                                  long propertyKeyId)

Get all constraints applicable to label and propertyKey. There are only UniquenessConstraint for the time being.

constraintsGetForLabel

Iterator<UniquenessConstraint> constraintsGetForLabel(long labelId)

Get all constraints applicable to label. There are only UniquenessConstraint for the time being.

constraintsGetAll

Iterator<UniquenessConstraint> constraintsGetAll()

Get all constraints. There are only UniquenessConstraint for the time being.

indexGetOwningUniquenessConstraintId
