This class implements an output stream in which the data is
written into a byte array. The buffer automatically grows as data
is written to it.
The data can be retrieved using toByteArray() and
toString().
Closing a ByteArrayOutputStream has no effect. The methods in
this class can be called after the stream has been closed without
generating an IOException.

toString(String charsetName) Converts the buffer's contents into a string by decoding the bytes using
the specified
java.nio.charset.Charset charsetName .
toString(int hibyte) Creates a newly allocated string.
public synchronized void
write(int b) Writes the specified byte to this byte array output stream.
public synchronized void
write(byte b, int off, int len) Writes len bytes from the specified byte array
starting at offset off to this byte array output stream.
public synchronized void
writeTo(OutputStream out) Writes the complete contents of this byte array output stream to
the specified output stream argument, as if by calling the output
stream's write method using out.write(buf, 0, count).
Creates a new byte array output stream, with a buffer capacity of
the specified size, in bytes.
Parameters: size - the initial size. exception: IllegalArgumentException - if size is negative.
Closing a ByteArrayOutputStream has no effect. The methods in
this class can be called after the stream has been closed without
generating an IOException.
Resets the count field of this byte array output
stream to zero, so that all currently accumulated output in the
output stream is discarded. The output stream can be used again,
reusing the already allocated buffer space.
See Also:java.io.ByteArrayInputStream.count
Returns the current size of the buffer.
the value of the count field, which is the numberof valid bytes in this output stream. See Also:java.io.ByteArrayOutputStream.count
Creates a newly allocated byte array. Its size is the current
size of this output stream and the valid contents of the buffer
have been copied into it.
the current contents of this output stream, as a byte array. See Also:java.io.ByteArrayOutputStream.size
Converts the buffer's contents into a string decoding bytes using the
platform's default character set. The length of the new String
is a function of the character set, and hence may not be equal to the
size of the buffer.
This method always replaces malformed-input and unmappable-character
sequences with the default replacement string for the platform's
default character set. The
class should be used when more control over the decoding process is
required.
String decoded from the buffer's contents. since: JDK1.1
Converts the buffer's contents into a string by decoding the bytes using
the specified
java.nio.charset.Charset charsetName . The length of
the new String is a function of the charset, and hence may not be
equal to the length of the byte array.
This method always replaces malformed-input and unmappable-character
sequences with this charset's default replacement string. The
java.nio.charset.CharsetDecoder class should be used when more control
over the decoding process is required.
Parameters: charsetName - the name of a supported String decoded from the buffer's contents. exception: UnsupportedEncodingException - If the named charset is not supported since: JDK1.1
toString
public synchronized String toString(int hibyte)(Code)
Creates a newly allocated string. Its size is the current size of
the output stream and the valid contents of the buffer have been
copied into it. Each character c in the resulting string is
constructed from the corresponding element b in the byte
array such that:
Writes the specified byte to this byte array output stream.
Parameters: b - the byte to be written.
write
public synchronized void write(byte b, int off, int len)(Code)
Writes len bytes from the specified byte array
starting at offset off to this byte array output stream.
Parameters: b - the data. Parameters: off - the start offset in the data. Parameters: len - the number of bytes to write.
Writes the complete contents of this byte array output stream to
the specified output stream argument, as if by calling the output
stream's write method using out.write(buf, 0, count).
Parameters: out - the output stream to which to write the data. exception: IOException - if an I/O error occurs.
