Enum Constant Detail

onCreate

public static final Merge onCreate

Allows definition of the action to take when a merge operation ends up not matching the search criteria. Typically, this event means that an Element will be created.

Since:

3.6.0

onMatch

public static final Merge onMatch

Allows definition of the action to take when a merge operation ends up successfully matching the search criteria. Typically, this event means that the matched Element will be returned.

Since:

3.6.0

outV

public static final Merge outV

Allows for more complex definition of the OUT vertex.

Since:

3.6.2

inV

public static final Merge inV

Allows for more complex definition of the IN vertex.

Since:

3.6.2

Method Detail

values

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

Returns:

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

valueOf

public static Merge 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
