Package com.arcadedb.graph

Class MutableVertex

java.lang.Object

com.arcadedb.database.BaseRecord

com.arcadedb.database.BaseDocument

com.arcadedb.database.MutableDocument

com.arcadedb.graph.MutableVertex

All Implemented Interfaces:

Document, Identifiable, Record, RecordInternal, Vertex, VertexInternal, Externalizable, Serializable

public class MutableVertex
extends MutableDocument
implements VertexInternal

Mutable vertex that supports updates. After any changes, call the method save() to mark the record as dirty in the current transaction, so the changes will be persistent at Transaction.commit() time.
