LongObjectIdback to summary
protected LongObjectId(AnyLongObjectId src)

Initialize this instance by copying another existing LongObjectId.

This constructor is mostly useful for subclasses which want to extend a LongObjectId with more properties, but initialize from an existing LongObjectId instance acquired by other means.

Parameters
src:AnyLongObjectId

another already parsed LongObjectId to copy the value out of.

Method Detail

equalsback to summary
public static boolean equals(final byte[] firstBuffer, final int fi, final byte[] secondBuffer, final int si)

Compare two object identifier byte sequences for equality.

Parameters
firstBuffer:byte[]

the first buffer to compare against. Must have at least 32 bytes from position fi through the end of the buffer.

fi:int

first offset within firstBuffer to begin testing.

secondBuffer:byte[]

the second buffer to compare against. Must have at least 32 bytes from position si through the end of the buffer.

si:int

first offset within secondBuffer to begin testing.

Returns:boolean

true if the two identifiers are the same.

fromHexStringback to summary
private static final LongObjectId fromHexString(byte[] bs, int p)
fromRawback to summary
public static final LongObjectId fromRaw(byte[] bs)

Convert a LongObjectId from raw binary representation.

Parameters
bs:byte[]

the raw byte buffer to read from. At least 32 bytes must be available within this byte array.

Returns:LongObjectId

the converted object id.

fromRawback to summary
public static final LongObjectId fromRaw(byte[] bs, int p)

Convert a LongObjectId from raw binary representation.

Parameters
bs:byte[]

the raw byte buffer to read from. At least 32 bytes after p must be available within this byte array.

p:int

position to read the first byte of data from.

Returns:LongObjectId

the converted object id.

fromRawback to summary

public LongObjectId toObjectId()

Implements abstract org.eclipse.jgit.lfs.lib.AnyLongObjectId.toObjectId.

Doc from org.eclipse.jgit.lfs.lib.AnyLongObjectId.toObjectId.

Obtain an immutable copy of this current object.

See copy() if this is a possibly subclassed (but immutable) identity and the application needs a lightweight identity only reference.

Returns:LongObjectId

an immutable copy. May be this if this is already an immutable instance.

Annotations
