Enum Constants

Enum Constant and Description
COMPUTED_NO_PREALLOCATE Kernel allocates and sets the validity bitmap of the output.
COMPUTED_PREALLOCATE Kernel expects a pre-allocated buffer to write the result bitmap into.
INTERSECTION Compute the output validity bitmap by intersecting the validity bitmaps of the arguments using bitwise-and operations.
OUTPUT_NOT_NULL Kernel output is never null and a validity bitmap does not need to be allocated.

Enum Constant Detail

INTERSECTION

public static final NullHandling.type INTERSECTION

Compute the output validity bitmap by intersecting the validity bitmaps of the arguments using bitwise-and operations. This means that values in the output are valid/non-null only if the corresponding values in all input arguments were valid/non-null. Kernel generally need not touch the bitmap thereafter, but a kernel's exec function is permitted to alter the bitmap after the null intersection is computed if it needs to.

COMPUTED_PREALLOCATE

public static final NullHandling.type COMPUTED_PREALLOCATE

Kernel expects a pre-allocated buffer to write the result bitmap into. The preallocated memory is not zeroed (except for the last byte), so the kernel should ensure to completely populate the bitmap.

COMPUTED_NO_PREALLOCATE

public static final NullHandling.type COMPUTED_NO_PREALLOCATE

Kernel allocates and sets the validity bitmap of the output.

OUTPUT_NOT_NULL

public static final NullHandling.type OUTPUT_NOT_NULL

Kernel output is never null and a validity bitmap does not need to be allocated.

Method Detail

values

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

Returns:

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

valueOf

public static NullHandling.type 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

intern

public NullHandling.type intern()

toString

public String toString()

Overrides:

toString in class Enum<NullHandling.type>
