Interface KernelAPI

public interface KernelAPI

The main API through which access to the Neo4j kernel is made, both read and write operations are supported as well as creating transactions. Changes to the graph (i.e. write operations) are performed via a transaction context where changes done inside the transaction are visible in read operations for statements executed within that transaction context. Once KernelTransaction.commit() committed} those changes are applied to the graph storage and made visible to all other transactions. Read operations not associated with any particular transaction can be performed via read-only statements.
