Method Detail

readUnsignedInt

public static int readUnsignedInt(java.io.ObjectInput in)
                           throws java.io.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:

java.io.IOException

readUnsignedInt

public static int readUnsignedInt(java.io.InputStream in)
                           throws java.io.IOException

Throws:

java.io.IOException

readUnsignedInt

public static int readUnsignedInt(java.nio.ByteBuffer in)

writeUnsignedInt

public static void writeUnsignedInt(java.io.ObjectOutput out,
                    int i)
                             throws java.io.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:

java.io.IOException

writeUnsignedInt

public static void writeUnsignedInt(java.io.OutputStream out,
                    int i)
