Enum GraphOp

java.lang.Object

java.lang.Enum<GraphOp>

org.apache.tinkerpop.gremlin.process.traversal.GraphOp

All Implemented Interfaces:

Serializable, Comparable<GraphOp>

public enum GraphOp
extends Enum<GraphOp>

A GraphOp or "graph operation" is a static Bytecode form that does not translate to a traversal but instead refers to a specific function to perform on a graph instance.

Enum Constant Detail

TX_COMMIT

public static final GraphOp TX_COMMIT

Commit a transaction.

TX_ROLLBACK

public static final GraphOp TX_ROLLBACK

Rollback a transaction.

Method Detail

values

public static GraphOp[] 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 (GraphOp c : GraphOp.values())
    System.out.println(c);

Returns:

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

valueOf

public static GraphOp 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

getBytecode

public Bytecode getBytecode()

Gets the Bytecode that represents this graph operation. There is no notion of immutable bytecode instances so it is important that the object returned here is not modified. If they are changed, the operations will no longer be recognized. In a future version, we should probably introduce the concept of immutable bytecode to prevent this possibility - https://issues.apache.org/jira/browse/TINKERPOP-2545

equals

public boolean equals(Bytecode bc)
