ByteArrayOutputStream

buf

byte[] buf

The buffer where data is stored.

count

int count

The number of valid bytes in the buffer.

ByteArrayOutputStream

ByteArrayOutputStream ()

Creates a new byte array output stream. The buffer capacity is initially 32 bytes, though its size increases if necessary.

ByteArrayOutputStream

ByteArrayOutputStream (int size)

Creates a new byte array output stream, with a buffer capacity of the specified size, in bytes.

close

void close ()

Closing a ByteArrayOutputStream has no effect. The methods in this class can be called after the stream has been closed without generating an IOException.

reset

void reset ()

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.

size

int size ()

Returns the current size of the buffer.

toByteArray

byte[] toByteArray ()

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.

toString

String toString (String charsetName)

Converts the buffer's contents into a string by decoding the bytes using the specified 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 CharsetDecoder class should be used when more control over the decoding process is required.

toString

String toString ()

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 CharsetDecoder class should be used when more control over the decoding process is required.

toString

String toString (int hibyte)

This method was deprecated in API level 1.
This method does not properly convert bytes into characters. As of JDK 1.1, the preferred way to do this is via the toString(String enc) method, which takes an encoding-name argument, or the toString() method, which uses the platform's default character encoding.

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:

     c == (char)(((hibyte & 0xff) << 8) | (b & 0xff))
 

write

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.

write

void write (int b)

Writes the specified byte to this byte array output stream.

writeTo

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).
