Interface StatementContext

All Superinterfaces:

Closeable, EntityOperations, LabelOperations, PropertyOperations, SchemaOperations

public interface StatementContext
extends EntityOperations, PropertyOperations, LabelOperations, SchemaOperations, Closeable

Interface for accessing and modifying the underlying graph. A statement is executing within a transaction and will be able to see all previous changes made within that transaction. When done using a statement it must be closed. Note that this interface only combines a set of interfaces that define operations that the database can perform. One main difference between a TransactionContext and a StatementContext is life cycle of some locks, where read locks can live within one statement, whereas write locks will live for the entire transaction.
