Enum Constant Detail

TLS

public static final NegotiationType TLS

Uses TLS ALPN/NPN negotiation, assumes an SSL connection.

PLAINTEXT_UPGRADE

public static final NegotiationType PLAINTEXT_UPGRADE

Use the HTTP UPGRADE protocol for a plaintext (non-SSL) upgrade from HTTP/1.1 to HTTP/2.

PLAINTEXT

public static final NegotiationType PLAINTEXT

Just assume the connection is plaintext (non-SSL) and the remote endpoint supports HTTP/2 directly without an upgrade.

Method Detail

values

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

Returns:

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

valueOf

public static NegotiationType 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
