Constructor Detail

TinyOutputStream

public TinyOutputStream(java.io.OutputStream out)

Creates a new output stream to write data to the specified underlying output stream.

Parameters:

out - the underlying output stream.

Method Detail

getSBLen

public static int getSBLen(int v)

Calculates how many bits are needed to store the specified signed value. Signed values are stored using at least 2 bits, so the function returns numbers from 2 to 32.

Parameters:

v - a signed integer value

Returns:

how many bits the specified value needs to be stored

getUBLen

public static int getUBLen(int v)

Calculates how many bits are needed to store the specified unsigned value. Unsigned values are stored using from 1 to 32 bits. For negative values, it returns 0.

Parameters:

v - a unsigned integer value

Returns:

how many bits the specified value needs to be stored

align

public void align()
           throws java.io.IOException

Aligns the stream

Throws:

java.io.IOException - if an I/O error has occurred

close

public void close()
           throws java.io.IOException

Closes this output stream and releases any system resources associated with this stream. A closed stream cannot perform output operations and cannot be reopened.

Throws:

java.io.IOException - if an I/O error occurs.

flush

public void flush()
           throws java.io.IOException

Flushes this output stream and forces any buffered output bytes to be written out.

Throws:

java.io.IOException - if an I/O error has occurred

writeBoolean

public void writeBoolean(boolean v)
                  throws java.io.IOException

Writes a boolean to the underlying output stream.

Parameters:

v - a boolean value to be written.

Throws:

java.io.IOException - if an I/O error occurs.

writeBytes

public void writeBytes(byte[] buffer)
                throws java.io.IOException

Writes buffer.length bytes from the specified byte array to this output stream.

Parameters:

buffer - buffer as byte array

Throws:

java.io.IOException - if an I/O error has occurred

writeSI16

public void writeSI16(short v)
               throws java.io.IOException

Writes a signed integer 16-bit value.

Parameters:

v - signed integer 16-bit value

Throws:

java.io.IOException - if an I/O error has occurred

writeSI32

public void writeSI32(int v)
               throws java.io.IOException

Writes a signed integer 32-bit value.

Parameters:

v - signed integer 32-bit value

Throws:

java.io.IOException - if an I/O error has occurred

writeSI8

public void writeSI8(byte v)
              throws java.io.IOException

Writes a signed integer 8-bit value.

Parameters:

v - signed integer 8-bit value

Throws:

java.io.IOException - if an I/O error has occurred

writeSB

public void writeSB(int v,
                    int n)
