GaleInputStream

public GaleInputStream(java.io.InputStream inputstream)

Method Detail

readUnicodeGivenCount

public final java.lang.String readUnicodeGivenCount(int i)
                                             throws java.io.IOException

readU32

public int readU32()
            throws java.io.IOException

readCountedUnicode

public final java.lang.String readCountedUnicode()
                                          throws java.io.IOException

readNullTerminated

public final java.lang.String readNullTerminated()
                                          throws java.io.IOException

Reads a null terminated string. This is a sequence of one-byte ISO-8859-1 characters, until the first nul ('\0') or until the end of the stream.

readRLE

public final void readRLE(byte[] encoded)
                   throws java.io.IOException

readRLE

public final java.math.BigInteger readRLE(int length)
                                   throws java.io.IOException

Reads length bytes of data from the stream and interprets it as an RLE encoded BigInteger

Parameters:

length - the number of bytes to read from the stream

Returns:

the BigInteger corresponding to the RLE decoded next length bytes

readTime

public Timestamp readTime()
                   throws java.io.IOException

Reads a time from the stream. Time is represented using 128 bits.

readFragment

public FragmentInterface readFragment()
                               throws java.io.IOException

readOperation

public OperationInterface readOperation()
                                 throws java.io.IOException

Reads the next operation from the stream.

Returns:

the next operation

Throws:

RecoverableCorruptionException - if there was a problem parsing the data, but all of the data was read from the stream, so that the stream is in a "good" state.

java.io.IOException - if there was a problem reading the data
