Method Detail

getOutBuffer

public byte[] getOutBuffer()

Returns the contents of this buffer as a byte array.

Returns:

the byte array

writeInteger

public void writeInteger(int intValue)
                  throws java.io.IOException

Writes a 32-bit signed integer value to the output buffer.

Parameters:

intValue - the integer value

Throws:

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

writeEnumeration

public void writeEnumeration(int enumeratedValue)
                      throws java.io.IOException

Writes an enumerated type value to the output buffer.

Parameters:

enumeratedValue - the enumerated type value

Throws:

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

writeBoolean

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

Writes a Java boolean value to the output buffer.

Parameters:

booleanValue - the boolean value

Throws:

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

writeBoolean

public boolean writeBoolean(int booleanValue)
                     throws java.io.IOException

Writes an integer boolean value to the output buffer.

Parameters:

booleanValue - the boolean value

Returns:

false if the boolean value is not 0 or 1, true otherwise

Throws:

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

writeLong

public void writeLong(long longValue)
               throws java.io.IOException

Writes a 64-bit signed integer value to the output buffer.

Parameters:

longValue - the integer value

Throws:

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

writeFloat

public void writeFloat(float floatValue)
                throws java.io.IOException

Writes a 32-bit floating point value to the output buffer.

Parameters:

floatValue - the floating point value

Throws:

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

writeDouble

public void writeDouble(double doubleValue)
                 throws java.io.IOException

Writes a 64-bit floating point value to the output buffer.

Parameters:

doubleValue - the floating point value

Throws:

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

writeFixedLengthOpaqueData

public void writeFixedLengthOpaqueData(byte[] bytes)
                                throws java.io.IOException

Writes an opaque (i.e., uninterpreted) array of bytes to the output buffer. Pad bytes (i.e., value of 0) are appended to the output to ensure that the total number of bytes written to the output buffer is a multiple of four.

Parameters:

bytes - the byte array

Throws:

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

writeVariableLengthOpaqueData

public void writeVariableLengthOpaqueData(byte[] bytes)
                                   throws java.io.IOException

Writes an opaque (i.e., uninterpreted) array of bytes to the output buffer. Four bytes, with the 32-bit unsigned integer value of the length of the byte array, are first written to the output buffer. Pad bytes (i.e., value of 0) are appended to the output to ensure that the total number of bytes written to the output buffer is a multiple of four.

Parameters:

bytes - the byte array

Throws:

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

writeString

public void writeString(java.lang.String stringValue)
                 throws java.io.UnsupportedEncodingException,
                        java.io.IOException

Writes a string to the output buffer. Four bytes, with the 32-bit unsigned integer value of the length of the byte array, are first written to the output buffer. Pad bytes (i.e., value of 0) are appended to the output to ensure that the total number of bytes written to the output buffer is a multiple of four.

Parameters:

stringValue - the string

Throws:

java.io.UnsupportedEncodingException - if the string encoding format (ISO-8859-1) is not available on the local platform

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