Class LongObjectId

    • Constructor Detail

      • LongObjectId

        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 - another already parsed LongObjectId to copy the value out of.

    • Method Detail

      • zeroId

        public static final LongObjectId zeroId()
        Get the special all-zero LongObjectId.
        Returns:
        the all-zero LongObjectId, often used to stand-in for no object.

      • isId

        public static final boolean isId​(String id)
        Test a string of characters to verify that it can be interpreted as LongObjectId.

        If true the string can be parsed with fromString(String).

        Parameters:
        id - the string to test.
        Returns:
        true if the string can converted into an LongObjectId.

      • toString

        public static final String toString​(LongObjectId i)
        Convert a LongObjectId into a hex string representation.
        Parameters:
        i - the id to convert. May be null.
        Returns:
        the hex string conversion of this id's content.

      • equals

        public static boolean equals​(byte[] firstBuffer,
                             int fi,
                             byte[] secondBuffer,
                             int si)
        Compare two object identifier byte sequences for equality.
        Parameters:
        firstBuffer - the first buffer to compare against. Must have at least 32 bytes from position fi through the end of the buffer.
        fi - first offset within firstBuffer to begin testing.
        secondBuffer - the second buffer to compare against. Must have at least 32 bytes from position si through the end of the buffer.
        si - first offset within secondBuffer to begin testing.
        Returns:
        true if the two identifiers are the same.

      • fromRaw

        public static final LongObjectId fromRaw​(byte[] bs)
        Convert a LongObjectId from raw binary representation.
        Parameters:
        bs - the raw byte buffer to read from. At least 32 bytes must be available within this byte array.
        Returns:
        the converted object id.

      • fromRaw

        public static final LongObjectId fromRaw​(byte[] bs,
                                         int p)
        Convert a LongObjectId from raw binary representation.
        Parameters:
        bs - the raw byte buffer to read from. At least 32 bytes after p must be available within this byte array.
        p - position to read the first byte of data from.
        Returns:
        the converted object id.

      • fromRaw

        public static final LongObjectId fromRaw​(long[] is)
        Convert a LongObjectId from raw binary representation.
        Parameters:
        is - the raw long buffer to read from. At least 4 longs must be available within this long array.
        Returns:
        the converted object id.

      • fromRaw

        public static final LongObjectId fromRaw​(long[] is,
                                         int p)
        Convert a LongObjectId from raw binary representation.
        Parameters:
        is - the raw long buffer to read from. At least 4 longs after p must be available within this long array.
        p - position to read the first long of data from.
        Returns:
        the converted object id.

      • fromString

        public static final LongObjectId fromString​(byte[] buf,
                                            int offset)
        Convert a LongObjectId from hex characters (US-ASCII).
        Parameters:
        buf - the US-ASCII buffer to read from. At least 64 bytes after offset must be available within this byte array.
        offset - position to read the first character from.
        Returns:
        the converted object id.

      • fromString

        public static LongObjectId fromString​(String str)
        Convert a LongObjectId from hex characters.
        Parameters:
        str - the string to read from. Must be 64 characters long.
        Returns:
        the converted object id.

      • toObjectId

        public LongObjectId toObjectId()
        Obtain an immutable copy of this current object.

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

        Specified by:
        toObjectId in class AnyLongObjectId
        Returns:
        an immutable copy. May be this if this is already an immutable instance.
