java.lang.Object

org.eclipse.jgit.lib.ObjectLoader

org.eclipse.jgit.lib.ObjectLoader.SmallObject

Enclosing class:

ObjectLoader

public static class ObjectLoader.SmallObject
extends ObjectLoader

Simple loader around the cached byte array.

ObjectReader implementations can use this stream type when the object's content is small enough to be accessed as a single byte array.

Constructor Detail

ObjectLoader.SmallObject

public ObjectLoader.SmallObject(int type,
                        byte[] data)

Construct a small object loader.

Parameters:

type - type of the object.

data - the object's data array. This array will be returned as-is for the getCachedBytes() method.

Method Detail

getType

public int getType()

Specified by:

getType in class ObjectLoader

Returns:

Git in pack object type, see Constants.

getSize

public long getSize()

Specified by:

getSize in class ObjectLoader

Returns:

size of object in bytes

isLarge

public boolean isLarge()

Overrides:

isLarge in class ObjectLoader

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()

Description copied from class: ObjectLoader

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 class ObjectLoader

Returns:

the cached bytes of this object. Do not modify it.

openStream

public ObjectStream openStream()

Description copied from class: ObjectLoader

Obtain an input stream to read this object's data.

Specified by:

openStream in class ObjectLoader

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.
