    • insert

      public ObjectId insert(int type, byte[] data, int off, int len) throws IOException
      Insert a single object into the store, returning its unique name.
      Overrides:
      insert in class ObjectInserter
      Parameters:
      type - type code of the object to store.
      data - complete content of the object.
      off - first position within data.
      len - number of bytes to copy from data.
      Returns:
      the name of the object.
      Throws:
      IOException - the object could not be stored.
    • insert

      private ObjectId insert(int type, byte[] data, int off, int len, boolean createDuplicate) throws IOException
      Insert a loose object into the database. If createDuplicate is true, write the loose object even if we already have it in the loose or packed ODB.
      Parameters:
      type -
      data -
      off -
      len -
      createDuplicate -
      Returns:
      ObjectId
      Throws:
      IOException
    • insert

      public ObjectId insert(int type, long len, InputStream is) throws IOException
      Insert a single object into the store, returning its unique name.
      Specified by:
      insert in class ObjectInserter
      Parameters:
      type - type code of the object to store.
      len - number of bytes to copy from in.
      is - stream providing the object content. The caller is responsible for closing the stream.
      Returns:
      the name of the object.
      Throws:
      IOException - the object could not be stored, or the source stream could not be read.
    • insert

      ObjectId insert(int type, long len, InputStream is, boolean createDuplicate) throws IOException
      Insert a loose object into the database. If createDuplicate is true, write the loose object even if we already have it in the loose or packed ODB.
      Parameters:
      type -
      len -
      is -
      createDuplicate -
      Returns:
      ObjectId
      Throws:
      IOException
    • insertOneObject

      private ObjectId insertOneObject(File tmp, ObjectId id, boolean createDuplicate) throws IOException
      Throws:
      IOException
    • newPackParser

      public PackParser newPackParser(InputStream in) throws IOException
      Initialize a parser to read from a pack formatted stream.
      Specified by:
      newPackParser in class ObjectInserter
      Parameters:
      in - the input stream. The stream is not closed by the parser, and must instead be closed by the caller once parsing is complete.
      Returns:
      the pack parser.
      Throws:
      IOException - the parser instance, which can be configured and then used to parse objects into the ObjectDatabase.
    • newReader

      public ObjectReader newReader()
      Open a reader for objects that may have been written by this inserter.

      The returned reader allows the calling thread to read back recently inserted objects without first calling flush() to make them visible to the repository. The returned reader should only be used from the same thread as the inserter. Objects written by this inserter may not be visible to this.newReader().newReader().

      The returned reader should return this inserter instance from ObjectReader.getCreatedFromInserter().

      Behavior is undefined if an insert method is called on the inserter in the middle of reading from an ObjectStream opened from this reader. For example, reading the remainder of the object may fail, or newly written data may even be corrupted. Interleaving whole object reads (including streaming reads) with inserts is fine, just not interleaving streaming partial object reads with inserts.

      Specified by:
      newReader in class ObjectInserter
      Returns:
      reader for any object, including an object recently inserted by this inserter since the last flush.
    • flush

      public void flush() throws IOException
      Make all inserted objects visible.

      The flush may take some period of time to make the objects available to other threads.

      Specified by:
      flush in class ObjectInserter
      Throws:
      IOException - the flush could not be completed; objects inserted thus far are in an indeterminate state.
    • close

      public void close()

      Release any resources used by this inserter.

      An inserter that has been released can be used again, but may need to be released after the subsequent usage.

      Specified by:
      close in interface AutoCloseable
      Specified by:
      close in class ObjectInserter
