Method Summary

Modifier and Type	Method	Description
LfsFactory.LfsInputStream	applyCleanFilter(Repository db, java.io.InputStream input, long length, Attribute attribute)	Apply clean filtering to the given stream, writing the file content to the LFS storage if required and returning a stream to the LFS pointer instead.
ObjectLoader	applySmudgeFilter(Repository db, ObjectLoader loader, Attribute attribute)	Apply smudge filtering to a given loader, potentially redirecting it to a LFS blob which is downloaded on demand.
LfsFactory.LfsInstallCommand	getInstallCommand()	Retrieve an LfsFactory.LfsInstallCommand which can be used to enable LFS support (if available) either per repository or for the user.
PrePushHook	getPrePushHook(Repository repo, java.io.PrintStream outputStream)	Retrieve a pre-push hook to be applied using the default error stream.
PrePushHook	getPrePushHook(Repository repo, java.io.PrintStream outputStream, java.io.PrintStream errorStream)	Retrieve a pre-push hook to be applied.

applySmudgeFilter

public ObjectLoader applySmudgeFilter(Repository db,
                                      ObjectLoader loader,
                                      Attribute attribute)
                               throws java.io.IOException

Description copied from class: LfsFactory

Apply smudge filtering to a given loader, potentially redirecting it to a LFS blob which is downloaded on demand.

Overrides:

applySmudgeFilter in class LfsFactory

Parameters:

db - the repository

loader - the loader for the blob

attribute - the attribute used to check for LFS enablement (i.e. "merge", "diff", "filter" from .gitattributes).

Returns:

a loader for the actual data of a blob, or the original loader in case LFS is not applicable.

Throws:

java.io.IOException

applyCleanFilter

public LfsFactory.LfsInputStream applyCleanFilter(Repository db,
                                                  java.io.InputStream input,
                                                  long length,
                                                  Attribute attribute)
                                           throws java.io.IOException

Description copied from class: LfsFactory

Apply clean filtering to the given stream, writing the file content to the LFS storage if required and returning a stream to the LFS pointer instead.

Overrides:

applyCleanFilter in class LfsFactory

Parameters:

db - the repository

input - the original input

length - the expected input stream length

attribute - the attribute used to check for LFS enablement (i.e. "merge", "diff", "filter" from .gitattributes).

Returns:

a stream to the content that should be written to the object store along with the expected length of the stream. the original stream is not applicable.

Throws:

java.io.IOException - in case of an error
