Method Detail
-
getType
public int getType()
Get Git in pack object type- Specified by:
getType
in classObjectLoader
- Returns:
- Git in pack object type, see
Constants
.
-
getSize
public long getSize()
Get size of object in bytes- Specified by:
getSize
in classObjectLoader
- Returns:
- size of object in bytes
-
isLarge
public boolean isLarge()
Whether this object is too large to obtain as a byte array.- Overrides:
isLarge
in classObjectLoader
- Returns:
- true if this object is too large to obtain as a byte array.
Objects over a certain threshold should be accessed only by their
ObjectLoader.openStream()
to prevent overflowing the JVM heap.
-
getCachedBytes
public byte[] getCachedBytes() throws LargeObjectException
Obtain a reference to the (possibly cached) bytes of this object.This method offers direct access to the internal caches, potentially saving on data copies between the internal cache and higher level code. Callers who receive this reference must not modify its contents. Changes (if made) will affect the cache but not the repository itself.
- Specified by:
getCachedBytes
in classObjectLoader
- Returns:
- the cached bytes of this object. Do not modify it.
- Throws:
LargeObjectException
- if the object won't fit into a byte array, becauseObjectLoader.isLarge()
returns true. Callers should useObjectLoader.openStream()
instead to access the contents.
-
openStream
public ObjectStream openStream() throws MissingObjectException, java.io.IOException
Obtain an input stream to read this object's data.- Specified by:
openStream
in classObjectLoader
- Returns:
- a stream of this object's data. Caller must close the stream when through with it. The returned stream is buffered with a reasonable buffer size.
- Throws:
MissingObjectException
- the object no longer exists.java.io.IOException
- the object store cannot be accessed.
-
getObjectId
private ObjectId getObjectId() throws java.io.IOException
- Throws:
java.io.IOException
