Enum Snapshot.ChecksumWriteMode

Object

Enum<Snapshot.ChecksumWriteMode>

io.delta.kernel.Snapshot.ChecksumWriteMode

All Implemented Interfaces:

Serializable, Comparable<Snapshot.ChecksumWriteMode>

Enclosing interface:

Snapshot

public static enum Snapshot.ChecksumWriteMode
extends Enum<Snapshot.ChecksumWriteMode>

Indicates how a checksum file should be written for this Snapshot. Use with Snapshot.writeChecksum(Engine, ChecksumWriteMode).

Enum Constant Summary

Enum Constants

Enum Constant	Description
FULL	Checksum info is not loaded in this Snapshot and requires replaying the delta log since the latest checksum (if present) to compute.
SIMPLE	Checksum info is already loaded in this Snapshot and can be written cheaply.

Method Summary

Modifier and Type	Method	Description
static Snapshot.ChecksumWriteMode	valueOf(String name)	Returns the enum constant of this type with the specified name.
static Snapshot.ChecksumWriteMode[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Details

SIMPLE

public static final Snapshot.ChecksumWriteMode SIMPLE

Checksum info is already loaded in this Snapshot and can be written cheaply. This mode uses pre-computed CRC information already in memory.

FULL

public static final Snapshot.ChecksumWriteMode FULL

Checksum info is not loaded in this Snapshot and requires replaying the delta log since the latest checksum (if present) to compute. This mode performs full computation and writing.

Method Details

values

public static Snapshot.ChecksumWriteMode[] values()

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

Returns:

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

valueOf

public static Snapshot.ChecksumWriteMode 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
