Method Detail

values

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

Returns:

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

valueOf

public static Cmp 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

hasNegation

public boolean hasNegation()

Description copied from interface: JanusGraphPredicate

Whether this predicate has a predicate that is semantically its negation. For instance, EQUAL and NOT_EQUAL are negatives of each other.

Specified by:

hasNegation in interface JanusGraphPredicate

Returns:

isQNF

public boolean isQNF()

Description copied from interface: JanusGraphPredicate

Returns true if this predicate is in query normal form.

Specified by:

isQNF in interface JanusGraphPredicate

Returns:
