Enum Constant Detail

DISABLED

public static final CompressionMode DISABLED

Couchbase Server will never send compressed values.

FORCED

public static final CompressionMode FORCED

Couchbase Server will always send compressed values, regardless of how the values are stored on the server, unless the compressed form is larger than the uncompressed form.

When connecting to a server older than version 5.5, this mode will be downgraded to DISABLED.

Since:

Couchbase Server 5.5 (Vulcan)

ENABLED

public static final CompressionMode ENABLED

Default mode.

Couchbase Server may send compressed values at its discretion. Values stored in compressed form will be sent compressed. Values stored in uncompressed form will be sent uncompressed.

When connecting to a server older than version 5.5, this mode will be downgraded to DISABLED.

Since:

Couchbase Server 5.5 (Vulcan)

Method Detail

values

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

Returns:

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

valueOf

public static CompressionMode 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

effectiveMode

public abstract CompressionMode effectiveMode(Version serverVersion)

Returns:

the mode specified by this enum value, or the fallback mode as required by the actual server version.

getDcpControls

public abstract Map<String,String> getDcpControls(Version serverVersion)

Returns:

the controls required to activate this compression mode.

getHelloFeatures

public Set<HelloFeature> getHelloFeatures(Version serverVersion)

Returns:

the HELLO features required to activate this compression mode.
