Enum Constant Detail

INTERSECT

public static final Geo INTERSECT

Whether the intersection between two geographic regions is non-empty

DISJOINT

public static final Geo DISJOINT

Whether the intersection between two geographic regions is empty

WITHIN

public static final Geo WITHIN

Whether one geographic region is completely contains within another

Method Detail

values

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

Returns:

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

valueOf

public static Geo 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

isValidCondition

public boolean isValidCondition(Object condition)

Description copied from interface: TitanPredicate

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 TitanPredicate

Returns:

isValidValueType

public boolean isValidValueType(Class<?> clazz)

Description copied from interface: TitanPredicate

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 TitanPredicate

Returns:

isQNF

public boolean isQNF()

Description copied from interface: TitanPredicate

Returns true if this predicate is in query normal form.

Specified by:

isQNF in interface TitanPredicate

Returns:
