Constructor Detail

AllOrNoneValueSet

public AllOrNoneValueSet(org.apache.arrow.vector.types.pojo.ArrowType type,
                         boolean all,
                         boolean nullAllowed)

Constructs a new AllOrNoneValueSet.

Parameters:

type - The Apache Arrow type of the field that this ValueSet applies to.

all - True if all non-null values are in this ValueSet.

nullAllowed - True is all null values are in this ValueSet.

Method Detail

isNullAllowed

public boolean isNullAllowed()

Conveys if nulls should be allowed.

Specified by:

isNullAllowed in interface ValueSet

Returns:

True if NULLs satisfy this constraint, false otherwise.

ValueSet

getType

public org.apache.arrow.vector.types.pojo.ArrowType getType()

The Arrow Type of the field this constraint applies to.

Specified by:

getType in interface ValueSet

Returns:

The ArrowType of the field this ValueSet applies to.

See Also:

ValueSet

isNone

public boolean isNone()

Conveys if no value can satisfy this ValueSet.

Specified by:

isNone in interface ValueSet

Returns:

True if no value can satisfy this ValueSet, false otherwise.

See Also:

ValueSet

isAll

public boolean isAll()

Conveys if any value can satisfy this ValueSet.

Specified by:

isAll in interface ValueSet

Returns:

True if any value can satisfy this ValueSet, false otherwise.

See Also:

ValueSet

isSingleValue

public boolean isSingleValue()

Conveys if this ValueSet contains a single value.

Specified by:

isSingleValue in interface ValueSet

Returns:

True if this ValueSet contains only a single value.

getSingleValue

public Object getSingleValue()

Attempts to return the single value contained in this ValueSet.

Specified by:

getSingleValue in interface ValueSet

Returns:

AllOrNoneValueSet never contains a single value, hence this method always throws UnsupportedOperationException.

containsValue

public boolean containsValue(Marker value)

Used to test if the supplied value (in the form of a Marker) is contained in this ValueSet.

Specified by:

containsValue in interface ValueSet

Parameters:

value - The value to test in the form of a Marker.

Returns:

True if the value is contained in the ValueSet, False otherwise.

containsValue

public boolean containsValue(Object value)

Used to test if the supplied value (in the form of a Marker) is contained in this ValueSet.

Specified by:

containsValue in interface ValueSet

Parameters:

value - The value to test in the form of a Marker.

Returns:

True if the value is contained in the ValueSet, False otherwise.

intersect

public ValueSet intersect(BlockAllocator allocator,
                          ValueSet other)

Specified by:

intersect in interface ValueSet

See Also:

ValueSet

union

public ValueSet union(BlockAllocator allocator,
                      ValueSet other)

Specified by:
