Enum VisorIgfsMode

java.lang.Object

java.lang.Enum<VisorIgfsMode>

org.apache.ignite.internal.visor.igfs.VisorIgfsMode

All Implemented Interfaces:

Serializable, Comparable<VisorIgfsMode>

Deprecated.

@Deprecated
public enum VisorIgfsMode
extends Enum<VisorIgfsMode>

IGFS mode defining interactions with underlying secondary Hadoop file system. Secondary Hadoop file system is provided for pass-through, write-through, and read-through purposes.

Enum Constant Summary

Enum Constants

Enum Constant and Description
DUAL_ASYNC Deprecated. In this mode IGFS will cache files locally and also asynchronously write them through to secondary Hadoop file system.
DUAL_SYNC Deprecated. In this mode IGFS will cache files locally and also synchronously write them through to secondary Hadoop file system.
PRIMARY Deprecated. In this mode IGFS will not delegate to secondary Hadoop file system and will cache all the files in memory only.
PROXY Deprecated. In this mode IGFS will not cache any files in memory and will only pass them through to secondary Hadoop file system.

Method Summary

Modifier and Type	Method and Description
static @Nullable VisorIgfsMode	fromOrdinal(int ord) Deprecated. Efficiently gets enumerated value from its ordinal.
static VisorIgfsMode	valueOf(String name) Deprecated. Returns the enum constant of this type with the specified name.
static VisorIgfsMode[]	values() Deprecated. Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

PRIMARY

public static final VisorIgfsMode PRIMARY

Deprecated.

In this mode IGFS will not delegate to secondary Hadoop file system and will cache all the files in memory only.

PROXY

public static final VisorIgfsMode PROXY

Deprecated.

In this mode IGFS will not cache any files in memory and will only pass them through to secondary Hadoop file system. If this mode is enabled, then secondary Hadoop file system must be configured.

DUAL_SYNC

public static final VisorIgfsMode DUAL_SYNC

Deprecated.

In this mode IGFS will cache files locally and also synchronously write them through to secondary Hadoop file system.

If secondary Hadoop file system is not configured, then this mode behaves like PRIMARY mode.

DUAL_ASYNC

public static final VisorIgfsMode DUAL_ASYNC

Deprecated.

In this mode IGFS will cache files locally and also asynchronously write them through to secondary Hadoop file system.

If secondary Hadoop file system is not configured, then this mode behaves like PRIMARY mode.

Method Detail

values

public static VisorIgfsMode[] values()

Deprecated.

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 (VisorIgfsMode c : VisorIgfsMode.values())
    System.out.println(c);

Returns:

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

valueOf

public static VisorIgfsMode valueOf(String name)

Deprecated.

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

fromOrdinal

@Nullable
public static @Nullable VisorIgfsMode fromOrdinal(int ord)

Deprecated.

Efficiently gets enumerated value from its ordinal.

Parameters:

ord - Ordinal value.

Returns:

Enumerated value or null if ordinal out of range.
