Class Operation

java.lang.Object
  org.apache.directory.mitosis.operation.Operation

All Implemented Interfaces:

java.io.Serializable

Direct Known Subclasses:

AddEntryOperation, AttributeOperation, CompositeOperation

public class Operation
extends java.lang.Object
implements java.io.Serializable

Represents an operation performed on one or more entries in replicated Partition. Each Operation has its own CSN which identifies itself.

An Operation is usually created by calling factory methods in OperationFactory, which produces a CompositeOperation of smaller multiple operations. For example, OperationFactory.newDelete(LdapDN) returns a CompositeOperation which consists of two ReplaceAttributeOperations; one updates Constants.ENTRY_CSN attribute and the other updates Constants.ENTRY_DELETED. Refer to OperationFactory to find out what LDAP/JNDI operation is translated into what Operation instance.
