Constructor Detail

TinyInputStream

public TinyInputStream(java.io.InputStream in)

Creates a new input stream with a default buffer size.

Parameters:

in - the input stream

Method Detail

read

public int read()
         throws java.io.IOException

Reads the next byte of data from the input stream. The value byte is returned as an int in the range 0 to 255. If no byte is available because the end of the stream has been reached, the value -1 is returned. This method blocks until input data is available, the end of the stream is detected, or an exception is thrown.

Returns:

the next byte of data, or -1 if the end of the stream is reached.

Throws:

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

available

public int available()
              throws java.io.IOException

Returns the number of bytes that can be read from this input stream without blocking.

Returns:

the number of bytes that can be read from the input in without blocking.

Throws:

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

close

public void close()
           throws java.io.IOException

Closes the input stream.

Throws:

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

skip

public long skip(long n)
          throws java.io.IOException

Skips the specified number of bytes.

Parameters:

n - the number of bytes to skip. Maximum the Integer.MAX_VALUE number of bytes to skip is allowed.

Returns:

the actual number of bytes skipped.

Throws:

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

align

public final void align()

Aligns the stream

readBoolean

public boolean readBoolean()
                    throws java.io.IOException

Reads a boolean value.

Returns:

a bollean value

Throws:

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

readSI16

public short readSI16()
               throws java.io.IOException

Reads a signed integer 16-bit value.

Returns:

a signed integer 16-bit value

Throws:

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

readSI32

public int readSI32()
             throws java.io.IOException

Reads a signed integer 32-bit value.

Returns:

a signed integer 32-bit value

Throws:

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

readSI8

public byte readSI8()
             throws java.io.IOException

Reads a signed integer 8-bit value.

Returns:

a signed integer 8-bit value

Throws:

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

readSB

public int readSB(int n)
           throws java.io.IOException

Reads a signed n-bit value.

Parameters:

n - the number of bits to be read

Returns:

a signed n-bit value.

Throws:

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

readTinyString

public TinyString readTinyString()
                          throws java.io.IOException

Reads a TinyString

Returns:

a TinyString object

Throws:

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

readUI16

public int readUI16()
             throws java.io.IOException

Reads an unsigned integer 16-bit value.

Returns:

an unsigned integer 16-bit value.

Throws:

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

readUI32

public int readUI32()
             throws java.io.IOException

Reads an unsigned integer 32-bit value.

Returns:

an unsigned integer 32-bit value.

Throws:

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

readUI8

public short readUI8()
              throws java.io.IOException
