Enum GraphProtocol

java.lang.Object

java.lang.Enum<GraphProtocol>

com.datastax.driver.dse.graph.GraphProtocol

All Implemented Interfaces:

Serializable, Comparable<GraphProtocol>

public enum GraphProtocol
extends Enum<GraphProtocol>

Defines a subprotocol to be used by the Java driver to communicate with DSE Graph. The subprotocol is stacked on top of the Apache Cassandra Native Protocol, and allows to handle the needs of specific DSE workloads.

Enum Constant Summary

Enum Constants

Enum Constant and Description
GRAPHSON_1_0 GraphSON1 is unsafe since it doesn't have an advanced typing format which causes type loss when transferring data to the server or receiving data.
GRAPHSON_2_0 Improvement of the GraphSON1 format that brings strong data-type information support.

Enum Constant Detail

GRAPHSON_1_0

public static final GraphProtocol GRAPHSON_1_0

GraphSON1 is unsafe since it doesn't have an advanced typing format which causes type loss when transferring data to the server or receiving data. We recommend using GRAPHSON_2_0 instead.

GRAPHSON_2_0

public static final GraphProtocol GRAPHSON_2_0

Improvement of the GraphSON1 format that brings strong data-type information support.

Method Detail

values

public static GraphProtocol[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (GraphProtocol c : GraphProtocol.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static GraphProtocol valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
