Http2Protocol

public Http2Protocol()

Method Detail

getHttpUpgradeName

public java.lang.String getHttpUpgradeName(boolean isSSLEnabled)

Specified by:

getHttpUpgradeName in interface UpgradeProtocol

Parameters:

isSSLEnabled - Is this for a connector that is configured to support TLS. Some protocols (e.g. HTTP/2) only support HTTP upgrade over non-secure connections.

Returns:

The name that clients will use to request an upgrade to this protocol via an HTTP/1.1 upgrade request or null if upgrade via an HTTP/1.1 upgrade request is not supported.

getAlpnIdentifier

public byte[] getAlpnIdentifier()

Specified by:

getAlpnIdentifier in interface UpgradeProtocol

Returns:

The byte sequence as listed in the IANA registry for this protocol or null if upgrade via ALPN is not supported.

getAlpnName

public java.lang.String getAlpnName()

Specified by:

getAlpnName in interface UpgradeProtocol

Returns:

The name of the protocol as listed in the IANA registry if and only if UpgradeProtocol.getAlpnIdentifier() returns the UTF-8 encoding of this name. If UpgradeProtocol.getAlpnIdentifier() returns some other byte sequence, then this method returns the empty string. If upgrade via ALPN is not supported then null is returned.

getProcessor

public Processor getProcessor(SocketWrapperBase<?> socketWrapper,
                              Adapter adapter)

Specified by:

getProcessor in interface UpgradeProtocol

Parameters:

socketWrapper - The socketWrapper for the connection that requires a processor

adapter - The Adapter instance that provides access to the standard Engine/Host/Context/Wrapper processing chain

Returns:

A processor instance for processing a connection using this protocol.

getInternalUpgradeHandler

public InternalHttpUpgradeHandler getInternalUpgradeHandler(Adapter adapter,
                                                            Request coyoteRequest)

Specified by:

getInternalUpgradeHandler in interface UpgradeProtocol

Parameters:

adapter - The Adapter to use to configure the new upgrade handler

coyoteRequest - A copy (may be incomplete) of the request that triggered the upgrade

Returns:

An instance of the HTTP upgrade handler for this protocol

accept

public boolean accept(Request request)

Description copied from interface: UpgradeProtocol

Allows the implementation to examine the request and accept or reject it based on what it finds.

Specified by:

accept in interface UpgradeProtocol

Parameters:

request - The request that included an upgrade header for this protocol

Returns:

true if the request is accepted, otherwise false
