Method Detail

isValidCondition

public boolean isValidCondition(Object condition)

Description copied from interface: JanusGraphPredicate

Whether the given condition is a valid condition for this predicate.

For instance, the Cmp.GREATER_THAN would require that the condition is comparable and not null.

Specified by:

isValidCondition in interface JanusGraphPredicate

Returns:

isValidValueType

public boolean isValidValueType(Class<?> clazz)

Description copied from interface: JanusGraphPredicate

Whether the given class is a valid data type for a value to which this predicate may be applied.

For instance, the Cmp.GREATER_THAN can only be applied to Comparable values.

Specified by:

isValidValueType in interface JanusGraphPredicate

Returns:

hasNegation

public boolean hasNegation()

Description copied from interface: JanusGraphPredicate

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

Specified by:

hasNegation in interface JanusGraphPredicate

Returns:

negate

public JanusGraphPredicate negate()

Description copied from interface: JanusGraphPredicate

Returns the negation of this predicate if it exists, otherwise an exception is thrown. Check JanusGraphPredicate.hasNegation() first.

Specified by:

negate in interface BiPredicate<Object,Object>

Specified by:

negate in interface JanusGraphPredicate

test

public boolean test(Object value,
                    Object condition)

Specified by:

test in interface BiPredicate<Object,Object>

Specified by:

test in interface JanusGraphPredicate
