Method Detail

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()

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(SqlFunctionProperties properties)

canonicalize

ValueSet canonicalize(boolean removeSafeConstants)

Returns:

A canonicalized ValueSet with a consistent representation. When removeSafeConstants is true, we return a ValueSet with all point constants removed, and range constants are kept. Example: `x = 1` is equivalent to `x = 1000` `x >= 1` is NOT equivalent to `x >= 1000` All types and bounds information is preserved.
