Method Details

none

static ValueSet none(Type type)

all

static ValueSet all(Type type)

of

static ValueSet of(Type type,
 Object first,
 Object... rest)

copyOf

static ValueSet copyOf(Type type,
 Collection<?> values)

ofRanges

static ValueSet ofRanges(Range first,
 Range... rest)

ofRanges

static ValueSet ofRanges(List<Range> ranges)

copyOfRanges

static ValueSet copyOfRanges(Type type,
 Collection<Range> ranges)

getType

Type getType()

isNone

boolean isNone()

isAll

boolean isAll()

isSingleValue

boolean isSingleValue()

getSingleValue

Object getSingleValue()

isDiscreteSet

boolean isDiscreteSet()

getDiscreteSet

List<Object> getDiscreteSet()

containsValue

boolean containsValue(Object value)

getDiscreteValues

default DiscreteValues getDiscreteValues()

Returns:

value predicates for equatable Types (but not orderable)

getRanges

default Ranges getRanges()

Returns:

range predicates for orderable Types

getValuesProcessor

ValuesProcessor getValuesProcessor()

intersect

ValueSet intersect(ValueSet other)

union

ValueSet union(ValueSet other)

union

default ValueSet union(Collection<ValueSet> valueSets)

complement

ValueSet complement()

overlaps

default boolean overlaps(ValueSet other)

subtract

default ValueSet subtract(ValueSet other)

contains

default boolean contains(ValueSet other)

toString

String toString()

Overrides:

toString in class Object

toString

String toString(ConnectorSession session)

toString

String toString(ConnectorSession session,
 int limit)

getRetainedSizeInBytes

long getRetainedSizeInBytes()

tryExpandRanges

Optional<Collection<Object>> tryExpandRanges(int valuesLimit)

Try to expand valueSet into a discrete set of (at most limit) objects. For example: [1, 5] can be expanded into {1, 2, 3, 4, 5}. If the data type is not supported or the expansion results in too many values, Optional.empty() is returned.
