All Implemented Interfaces:

ExtensionPoint

Enclosing class:

SCMFileSystem

public abstract static class SCMFileSystem.Builder
extends Object
implements ExtensionPoint

Extension point that allows different plugins to implement SCMFileSystem classes for the same SCM or SCMSource and let Jenkins pick the most capable for any specific SCM implementation.

Method Detail

supports

public abstract boolean supports(SCM source)

Checks if this SCMFileSystem.Builder supports the supplied SCM.

Parameters:

source - the SCM.

Returns:

true if and only if the supplied SCM is supported by this SCMFileSystem.Builder, false if build(Item, SCM, SCMRevision) will always return null.

supports

public abstract boolean supports(SCMSource source)

Checks if this SCMFileSystem.Builder supports the supplied SCMSource.

Parameters:

source - the SCMSource.

Returns:

true if and only if the supplied SCMSource is supported by this SCMFileSystem.Builder, false if build(SCMSource, SCMHead, SCMRevision) will always return null.

supports

public final boolean supports(SCMDescriptor<?> descriptor)

Checks if this SCMFileSystem.Builder supports the supplied SCMDescriptor.

Parameters:

descriptor - the SCMDescriptor

Returns:

the return value of supportsDescriptor(SCMDescriptor) if implemented, otherwise, it will return true if one of the following is true: the SCM for the descriptor is the enclosing class of this builder class, the builder and SCM are in the same package, or the builder is in a child package of the SCM.

Since:

2.3.0

supportsDescriptor

protected abstract boolean supportsDescriptor(SCMDescriptor descriptor)

Checks if this SCMFileSystem.Builder supports the supplied SCMDescriptor.

Parameters:

descriptor - the SCMDescriptor

Returns:

true if and only if the supplied SCMSourceDescriptor's SCMDescriptor class is supported by this SCMFileSystem.Builder.

Since:

2.3.0

supports

public final boolean supports(SCMSourceDescriptor descriptor)

Checks if this SCMFileSystem.Builder supports the supplied SCMSourceDescriptor.

Parameters:

descriptor - the SCMSourceDescriptor

Returns:

the return value of supportsDescriptor(SCMSourceDescriptor) if implemented, otherwise, it will return true if one of the following is true: the SCMSource for the descriptor is the enclosing class of this builder class, the builder and SCMSource are in the same package, or the builder is in a child package of the SCMSource.

Since:

2.3.0

supportsDescriptor

protected abstract boolean supportsDescriptor(SCMSourceDescriptor descriptor)

Checks if this SCMFileSystem.Builder supports the supplied SCMSourceDescriptor.

Parameters:

descriptor - the SCMSourceDescriptor

Returns:

true if and only if the supplied SCMSourceDescriptor's SCMSource class is supported by this SCMFileSystem.Builder, false if build(SCMSource, SCMHead, SCMRevision) will always return null, and false by default for compatibility.

Since:

2.3.0

build

@CheckForNull
public abstract SCMFileSystem build(@NonNull
                                                  Item owner,
                                                  @NonNull
                                                  SCM scm,
                                                  @CheckForNull
                                                  SCMRevision rev)
                                           throws IOException,
                                                  InterruptedException

Given a SCM this should try to build a corresponding SCMFileSystem instance that reflects the content at the specified SCMRevision. If the SCM is supported but not for a fixed revision, best effort is acceptable as the most capable SCMFileSystem will be returned to the caller.

Parameters:

owner - the owner of the SCM

scm - the SCM.

rev - the specified SCMRevision.

Returns:

the corresponding SCMFileSystem or null if this builder cannot create a SCMFileSystem for the specified SCM.

Throws:

IOException - if the attempt to create a SCMFileSystem failed due to an IO error (such as the remote system being unavailable)

InterruptedException - if the attempt to create a SCMFileSystem was interrupted.

@CheckForNull

                                         SCMSource source,

                                         InterruptedException

Given a SCMSource, a SCMHead and a SCMRevision this method should try to build a corresponding SCMFileSystem instance that reflects the content of the specified SCMHead at the specified SCMRevision. If the SCMSource is supported but not for a fixed revision, best effort is acceptable as the most capable SCMFileSystem will be returned to the caller.

Parameters:

source - the SCMSource.

head - the specified SCMHead.

rev - the specified SCMRevision.

Returns:

the corresponding SCMFileSystem or null if there is none.

Throws:

IOException - if the attempt to create a SCMFileSystem failed due to an IO error (such as the remote system being unavailable)

InterruptedException - if the attempt to create a SCMFileSystem was interrupted.
