REQUIRED_INSTRUCTION	Support for the "required" instruction.
TIMEZONE_HANDSHAKE	Support for the "timezone" handshake instruction.

Method Summary

Modifier and Type	Method	Description
boolean	isSupported(GuacamoleProtocolVersion version)	Returns whether this capability is supported in the given Guacamole protocol version.
static GuacamoleProtocolCapability	valueOf(String name)	Returns the enum constant of this type with the specified name.

Enum Constant Detail

ARBITRARY_HANDSHAKE_ORDER

public static final GuacamoleProtocolCapability ARBITRARY_HANDSHAKE_ORDER

The protocol does not require handshake instructions to be sent in a specific order, nor that all handshake instructions be sent. Arbitrary handshake order was introduced in GuacamoleProtocolVersion.VERSION_1_1_0.

PROTOCOL_VERSION_DETECTION

public static final GuacamoleProtocolCapability PROTOCOL_VERSION_DETECTION

Negotiation of Guacamole protocol version between client and server during the protocol handshake. The ability to negotiate protocol versions was introduced in GuacamoleProtocolVersion.VERSION_1_1_0.

REQUIRED_INSTRUCTION

public static final GuacamoleProtocolCapability REQUIRED_INSTRUCTION

Support for the "required" instruction. The "required" instruction allows the server to explicitly request connection parameters from the client without which the connection cannot continue, such as user credentials. Support for this instruction was introduced in GuacamoleProtocolVersion.VERSION_1_3_0.

TIMEZONE_HANDSHAKE

public static final GuacamoleProtocolCapability TIMEZONE_HANDSHAKE

Support for the "timezone" handshake instruction. The "timezone" instruction allows the client to request that the server forward their local timezone for use within the remote desktop session. Support for forwarding the client timezone was introduced in GuacamoleProtocolVersion.VERSION_1_1_0.

Method Detail

values

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

Returns:

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

valueOf

public static GuacamoleProtocolCapability 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

isSupported

public boolean isSupported(GuacamoleProtocolVersion version)

Returns whether this capability is supported in the given Guacamole protocol version.

Parameters:

version - The Guacamole protocol version to check.

Returns:

true if this capability is supported by the given protocol version, false otherwise.
