Class TransportProtocol
- Direct Known Subclasses:
TestProtocol
Implementations of this class are typically immutable singletons held by static class members, for example:
package com.example.my_transport; class MyTransport extends Transport { public static final TransportProtocol PROTO = new TransportProtocol() { public String getName() { return "My Protocol"; } }; }
Applications may register additional protocols for use by JGit by calling
Transport.register(TransportProtocol)
.
Because that API holds onto the protocol object by a WeakReference,
applications must ensure their own ClassLoader retains the TransportProtocol
for the life of the application. Using a static singleton pattern as above
will ensure the protocol is valid so long as the ClassLoader that defines it
remains valid.
Applications may automatically register additional protocols by filling in
the names of their TransportProtocol defining classes using the services file
META-INF/services/org.eclipse.jgit.transport.Transport
. For each
class name listed in the services file, any static fields of type
TransportProtocol
will be automatically registered. For the above
example the string com.example.my_transport.MyTransport
should be
listed in the file, as that is the name of the class that defines the static
PROTO singleton.

Method Details
-
getName
Get text name of the protocol suitable for display to a user.- Returns:
- text name of the protocol suitable for display to a user.
-
getSchemes
Get immutable set of schemes supported by this protocol.- Returns:
- immutable set of schemes supported by this protocol.
-
getRequiredFields
Get immutable set of URIishFields that must be filled in.- Returns:
- immutable set of URIishFields that must be filled in.
-
getOptionalFields
Get immutable set of URIishFields that may be filled in.- Returns:
- immutable set of URIishFields that may be filled in.
-
getDefaultPort
public int getDefaultPort()Get the default port if the protocol supports a port, else -1.- Returns:
- the default port if the protocol supports a port, else -1.
-
canHandle
Determine if this protocol can handle a particular URI.Implementations should try to avoid looking at the local filesystem, but may look at implementation specific configuration options in the remote block of
local.getConfig()
usingremoteName
if the name is non-null.The default implementation of this method matches the scheme against
getSchemes()
, required fields againstgetRequiredFields()
, and optional fields againstgetOptionalFields()
, returning true only if all of the fields match the specification.- Parameters:
uri
- address of the Git repository; never null.- Returns:
- true if this protocol can handle this URI; false otherwise.
-
canHandle
Determine if this protocol can handle a particular URI.Implementations should try to avoid looking at the local filesystem, but may look at implementation specific configuration options in the remote block of
local.getConfig()
usingremoteName
if the name is non-null.The default implementation of this method matches the scheme against
getSchemes()
, required fields againstgetRequiredFields()
, and optional fields againstgetOptionalFields()
, returning true only if all of the fields match the specification.- Parameters:
uri
- address of the Git repository; never null.local
- the local repository that will communicate with the other Git repository. May be null if the caller is only asking about a specific URI and does not have a local Repository.remoteName
- name of the remote, if the remote as configured inlocal
; otherwise null.- Returns:
- true if this protocol can handle this URI; false otherwise.
-
open
public abstract Transport open(URIish uri, Repository local, String remoteName) throws NotSupportedException, TransportException Open a Transport instance to the other repository.Implementations should avoid making remote connections until an operation on the returned Transport is invoked, however they may fail fast here if they know a connection is impossible, such as when using the local filesystem and the target path does not exist.
Implementations may access implementation-specific configuration options within
local.getConfig()
using the remote block named by theremoteName
, if the name is non-null.- Parameters:
uri
- address of the Git repository.local
- the local repository that will communicate with the other Git repository.remoteName
- name of the remote, if the remote as configured inlocal
; otherwise null.- Returns:
- the transport.
- Throws:
NotSupportedException
- this protocol does not support the URI.TransportException
- the transport cannot open this URI.
-
open
Open a new transport instance to the remote repository. Use default configuration instead of reading from configuration files.- Parameters:
uri
- aURIish
object.- Returns:
- new Transport
- Throws:
NotSupportedException
TransportException
