public enum GraphOp extends Enum<GraphOp>
AGraphOp
or "graph operation" is a staticBytecode
form that does not translate to a traversal but instead refers to a specific function to perform on a graph instance.

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 nameNullPointerException
- if the argument is null
-
getBytecode
public Bytecode getBytecode()
Gets theBytecode
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
