All Implemented Interfaces:

Serializable, Comparable<Compare>, BiPredicate<Object,Object>, PBiPredicate<Object,Object>

public enum Compare
extends Enum<Compare>
implements PBiPredicate<Object,Object>

Compare is a BiPredicate that determines whether the first argument is ==, !=, >, >=, <, <= to the second argument.

Enum Constant Summary

Enum Constants

Enum Constant	Description
eq	Evaluates if the first object is equal to the second per Gremlin Comparison semantics.
gt	Evaluates if the first object is greater than the second per Gremlin Comparison semantics.
gte	Evaluates if the first object is greater-equal to the second per Gremlin Comparison semantics.
lt	Evaluates if the first object is less than the second per Gremlin Comparison semantics.
lte	Evaluates if the first object is less-equal to the second per Gremlin Comparison semantics.
neq	Evaluates if the first object is not equal to the second per Gremlin Comparison semantics.

Method Summary

Modifier and Type	Method	Description
abstract Compare	negate()	Produce the opposite representation of the current Compare enum.
static Compare	valueOf(String name)	Returns the enum constant of this type with the specified name.
static Compare[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Method Detail

values

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

Returns:

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

valueOf

public static Compare 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

negate

public abstract Compare negate()

Produce the opposite representation of the current Compare enum.

Specified by:

negate in interface BiPredicate<Object,Object>

Specified by:

negate in interface PBiPredicate<Object,Object>
