Class RegularGraphStatement

java.lang.Object

com.datastax.driver.dse.graph.GraphStatement

com.datastax.driver.dse.graph.RegularGraphStatement

Direct Known Subclasses:

SimpleGraphStatement

public abstract class RegularGraphStatement
extends GraphStatement

A regular (non-prepared and non batched) graph statement.

This class represents a graph query string along with query options (and optionally values). It can be extended, but SimpleGraphStatement is provided as a simple implementation to build a RegularGraphStatement directly from its query string.

public abstract RegularStatement unwrap()

Description copied from class: GraphStatement

"Unwraps" the current graph statement, that is, returns an executable Statement object corresponding to this graph statement.

This method is intended for internal use only, users wishing to execute graph statements should use DseSession.executeGraph(GraphStatement).

This method acts as a bridge between graph statements and regular Statements.

Implementations are free to cache the returned Statement if appropriate.
