Method Detail

readUnsignedInt

public static int readUnsignedInt(ObjectInput in)
                           throws IOException

Reads an int stored in variable-length format. Reads between one and five bytes. Smaller values take fewer bytes. Negative numbers are not supported.

Throws:

IOException

writeUnsignedInt

public static void writeUnsignedInt(ObjectOutput out,
                                    int i)
                             throws IOException

Writes an int in a variable-length format. Writes between one and five bytes. Smaller values take fewer bytes. Negative numbers are not supported.

Parameters:

i - int to write

Throws:

IOException

readUnsignedLong

public static long readUnsignedLong(ObjectInput in)
                             throws IOException

Reads an int stored in variable-length format. Reads between one and nine bytes. Smaller values take fewer bytes. Negative numbers are not supported.

Throws:

IOException

writeUnsignedLong

public static void writeUnsignedLong(ObjectOutput out,
                                     long i)
                              throws IOException

Writes an int in a variable-length format. Writes between one and nine bytes. Smaller values take fewer bytes. Negative numbers are not supported.

Parameters:

i - int to write

Throws:

IOException

readUnsignedInt

public static int readUnsignedInt(byte[] bytes,
                                  int offset)
                           throws IOException

Reads an int stored in variable-length format. Reads between one and five bytes. Smaller values take fewer bytes. Negative numbers are not supported.

Throws:

IOException

writeUnsignedInt

                             throws IOException

Writes an int in a variable-length format. Writes between one and five bytes. Smaller values take fewer bytes. Negative numbers are not supported.

Parameters:

i - int to write

Throws:

IOException
