Method Detail

encodeBinary

public void encodeBinary(byte[] b)
                  throws IOException

Encode a binary value as a length-prefixed sequence of octets.

Specified by:

encodeBinary in interface EncoderChannel

Parameters:

b - byte array

Throws:

IOException - IO exception

encodeString

public void encodeString(String s)
                  throws IOException

Encode a string as a length-prefixed sequence of UCS codepoints, each of which is encoded as an integer. Look for codepoints of more than 16 bits that are represented as UTF-16 surrogate pairs in Java.

Specified by:

encodeString in interface EncoderChannel

Parameters:

s - string

Throws:

IOException - IO exception

encodeStringOnly

public void encodeStringOnly(String s)
                      throws IOException

Description copied from interface: EncoderChannel

Encode a string as a sequence of UCS codepoints, each of which is encoded as an integer. Look for codepoints of more than 16 bits that are represented as UTF-16 surrogate pairs in Java.

Specified by:

encodeStringOnly in interface EncoderChannel

Parameters:

s - string

Throws:

IOException - IO exception

encodeInteger

public void encodeInteger(int n)
                   throws IOException

Encode an arbitrary precision integer using a sign bit followed by a sequence of octets. The most significant bit of the last octet is set to zero to indicate sequence termination. Only seven bits per octet are used to store the integer's value.

Specified by:

encodeInteger in interface EncoderChannel

Parameters:

n - integer

Throws:

IOException - IO exception

encodeLong

protected void encodeLong(long l)
                   throws IOException

Throws:

IOException

encodeBigInteger

protected void encodeBigInteger(BigInteger bi)
                         throws IOException

Throws:

IOException

encodeIntegerValue

public void encodeIntegerValue(IntegerValue iv)
                        throws IOException

Specified by:

encodeIntegerValue in interface EncoderChannel

Throws:

IOException

encodeUnsignedInteger

public void encodeUnsignedInteger(int n)
                           throws IOException

Encode an arbitrary precision non negative integer using a sequence of octets. The most significant bit of the last octet is set to zero to indicate sequence termination. Only seven bits per octet are used to store the integer's value.

Specified by:

encodeUnsignedInteger in interface EncoderChannel

Parameters:

n - unsigned integer

Throws:

IOException - IO exception

encodeUnsignedLong

protected void encodeUnsignedLong(long l)
                           throws IOException

Throws:

IOException

encodeUnsignedBigInteger

protected void encodeUnsignedBigInteger(BigInteger bi)
                                 throws IOException

Throws:

IOException

encodeUnsignedIntegerValue

public void encodeUnsignedIntegerValue(IntegerValue iv)
                                throws IOException

Specified by:

encodeUnsignedIntegerValue in interface EncoderChannel

Throws:

IOException

encodeDecimal

public void encodeDecimal(boolean negative,
                          IntegerValue integral,
                          IntegerValue reverseFraction)
                   throws IOException,
                          RuntimeException

Encode a decimal represented as a Boolean sign followed by two Unsigned Integers. A sign value of zero (0) is used to represent positive Decimal values and a sign value of one (1) is used to represent negative Decimal values The first Integer represents the integral portion of the Decimal value. The second positive integer represents the fractional portion of the decimal with the digits in reverse order to preserve leading zeros.

Specified by:

encodeDecimal in interface EncoderChannel

Parameters:

negative - is negative

integral - integral value

reverseFraction - reverse fraction

Throws:

IOException - IO exception

RuntimeException

encodeFloat

public void encodeFloat(FloatValue fv)
                 throws IOException

Encode a Float represented as two consecutive Integers. The first Integer represents the mantissa of the floating point number and the second Integer represents the 10-based exponent of the floating point number

Specified by:

encodeFloat in interface EncoderChannel

Parameters:

fv - float value

Throws:

IOException - IO exception

encodeDateTime

public void encodeDateTime(DateTimeValue datetime)
                    throws IOException

Description copied from interface: EncoderChannel
