Method Details

open

public static CommitGraph open(File graphFile)
                        throws FileNotFoundException,
CommitGraphFormatException,
IOException

Open an existing commit-graph file for reading.

The format of the file will be automatically detected and a proper access implementation for that format will be constructed and returned to the caller. The file may or may not be held open by the returned instance.

Parameters:

graphFile - existing commit-graph to read.

Returns:

a copy of the commit-graph file in memory

Throws:

FileNotFoundException - the file does not exist.

CommitGraphFormatException - commit-graph file's format is different from we expected.

IOException - the file exists but could not be read due to security errors or unexpected data corruption.

read

public static CommitGraph read(InputStream fd)
                        throws CommitGraphFormatException,
IOException

Read an existing commit-graph file from a buffered stream.

The format of the file will be automatically detected and a proper access implementation for that format will be constructed and returned to the caller. The file may or may not be held open by the returned instance.

Parameters:

fd - stream to read the commit-graph file from. The stream must be buffered as some small IOs are performed against the stream. The caller is responsible for closing the stream.

Returns:

a copy of the commit-graph file in memory

Throws:

CommitGraphFormatException - the commit-graph file's format is different from we expected.

IOException - the stream cannot be read.

read

public static CommitGraph read(InputStream fd,
 boolean readChangedPathFilters)
                        throws CommitGraphFormatException,
IOException

Read an existing commit-graph file from a buffered stream.

The format of the file will be automatically detected and a proper access implementation for that format will be constructed and returned to the caller. The file may or may not be held open by the returned instance.

Parameters:

fd - stream to read the commit-graph file from. The stream must be buffered as some small IOs are performed against the stream. The caller is responsible for closing the stream.

readChangedPathFilters - enable reading bloom filter chunks.

Returns:

a copy of the commit-graph file in memory

Throws:

CommitGraphFormatException - the commit-graph file's format is different from we expected.

IOException - the stream cannot be read.
