- Constructor Detail
  - 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(SocketWrapperBase<?> socketWrapper,
                                                            Adapter adapter,
                                                            Request coyoteRequest)
```
    Specified by:
    
    getInternalUpgradeHandler in interface UpgradeProtocol
    
    Parameters:
    
    socketWrapper - The socket
    
    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
