Direct Known Subclasses:

GraphStatement, RowStatement

public abstract class Statement
extends java.lang.Object

Neo4J supports two forms fo Statement Requests: Graphs and Rows.

Unlike JDBC in which statements are created from a connection, the Neo4J Driver actually allows developers to create as many statements as they like on a single transaction (supported through the Connection#add(Statement) method).

Results are also specific to the statement and can be retrieved via the #getResult() method.

NOTE: This API will probably change to support a builder style Statement builder.
