Method Details

readUnsignedInt

public static int readUnsignedInt(DataInput 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

readUnsignedInt

public static int readUnsignedInt(InputStream in)
                           throws IOException

Throws:

IOException

readUnsignedInt

public static int readUnsignedInt(ByteBuffer in)

writeUnsignedInt

public static void writeUnsignedInt(DataOutput 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

writeUnsignedInt

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

Throws:

IOException

sizeUnsignedInt

public static byte sizeUnsignedInt(int i)

writeUnsignedInt

public static void writeUnsignedInt(ByteBuffer out,
 int i)

readUnsignedLong

public static long readUnsignedLong(DataInput in)
                             throws IOException

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

Throws:

IOException
