Java Source Code / Java Documentation » Apache Harmony Java SE » java package » java.io   Source Cross Reference   Class Diagram   Java Document (Java Doc)   java.lang.Object    java.io.OutputStream       java.io.ByteArrayOutputStream ByteArrayOutputStream public class ByteArrayOutputStream extends OutputStream (Code) ByteArrayOutputStream is a class whose underlying stream is represented by a byte array. As bytes are written to this stream, the local byte array may be expanded to hold more bytes. See Also:   ByteArrayInputStream Field Summary protected  byte[] buf      The byte array containing the bytes written. protected  int count      The number of bytes written. Constructor Summary public   ByteArrayOutputStream()      Constructs a new ByteArrayOutputStream with a default size of 32 bytes. public   ByteArrayOutputStream(int size)      Constructs a new ByteArrayOutputStream with a default size of size bytes. Method Summary public  void close()      Close this ByteArrayOutputStream. public synchronized  void reset()      Reset this ByteArrayOutputStream to the beginning of the underlying byte array. public  int size()      Answers the total number of bytes written to this stream thus far. public synchronized  byte[] toByteArray()      Answer the contents of this ByteArrayOutputStream as a byte array. public  String toString()      Answer the contents of this ByteArrayOutputStream as a String. public  String toString(int hibyte)      Answer the contents of this ByteArrayOutputStream as a String. public  String toString(String enc)      Answer the contents of this ByteArrayOutputStream as a String converted using the encoding declared in enc. Parameters:   enc - A String representing the encoding to use when translatingthis stream to a String. public synchronized  void write(byte[] buffer, int offset, int len)      Writes count bytes from the byte array buffer starting at offset index to the ByteArrayOutputStream. public synchronized  void write(int oneByte)      Writes the specified byte oneByte to the OutputStream. public synchronized  void writeTo(OutputStream out)      Take the contents of this stream and write it to the output stream out. Field Detail buf protected byte[] buf(Code) The byte array containing the bytes written. count protected int count(Code) The number of bytes written. Constructor Detail ByteArrayOutputStream public ByteArrayOutputStream()(Code) Constructs a new ByteArrayOutputStream with a default size of 32 bytes. If more than 32 bytes are written to this instance, the underlying byte array will expand to accommodate. ByteArrayOutputStream public ByteArrayOutputStream(int size)(Code) Constructs a new ByteArrayOutputStream with a default size of size bytes. If more than size bytes are written to this instance, the underlying byte array will expand to accommodate. Parameters:   size - an non-negative integer representing the initial size for theunderlying byte array. Method Detail close public void close() throws IOException(Code) Close this ByteArrayOutputStream. This implementation releases System resources used for this stream. throws:   IOException - If an error occurs attempting to close this OutputStream. reset public synchronized void reset()(Code) Reset this ByteArrayOutputStream to the beginning of the underlying byte array. All subsequent writes will overwrite any bytes previously stored in this stream. size public int size()(Code) Answers the total number of bytes written to this stream thus far. the number of bytes written to this Stream. toByteArray public synchronized byte[] toByteArray()(Code) Answer the contents of this ByteArrayOutputStream as a byte array. Any changes made to the receiver after returning will not be reflected in the byte array returned to the caller. this streams current contents as a byte array. toString public String toString()(Code) Answer the contents of this ByteArrayOutputStream as a String. Any changes made to the receiver after returning will not be reflected in the String returned to the caller. this streams current contents as a String. toString public String toString(int hibyte)(Code) Answer the contents of this ByteArrayOutputStream as a String. Each byte b in this stream is converted to a character c using the following function: c == (char)(((hibyte & 0xff) << 8) | (b & 0xff)). This method is deprecated and either toString(), or toString(enc) should be used. Parameters:   hibyte - the high byte of each resulting Unicode character this streams current contents as a String with the high byte setto hibyte toString public String toString(String enc) throws UnsupportedEncodingException(Code) Answer the contents of this ByteArrayOutputStream as a String converted using the encoding declared in enc. Parameters:   enc - A String representing the encoding to use when translatingthis stream to a String. this streams current contents as a String. throws:   UnsupportedEncodingException - If declared encoding is not supported write public synchronized void write(byte[] buffer, int offset, int len)(Code) Writes count bytes from the byte array buffer starting at offset index to the ByteArrayOutputStream. Parameters:   buffer - the buffer to be written Parameters:   offset - offset in buffer to get bytes Parameters:   len - number of bytes in buffer to write throws:   NullPointerException - If buffer is null. throws:   IndexOutOfBoundsException - If offset or count are outside of bounds. write public synchronized void write(int oneByte)(Code) Writes the specified byte oneByte to the OutputStream. Only the low order byte of oneByte is written. Parameters:   oneByte - the byte to be written writeTo public synchronized void writeTo(OutputStream out) throws IOException(Code) Take the contents of this stream and write it to the output stream out. Parameters:   out - An OutputStream on which to write the contents of this stream. throws:   IOException - If an error occurs when writing to output stream Methods inherited from java.io.OutputStream public void close() throws IOException(Code)(Java Doc) public void flush() throws IOException(Code)(Java Doc) public void write(byte buffer) throws IOException(Code)(Java Doc) public void write(byte buffer, int offset, int count) throws IOException(Code)(Java Doc) abstract public void write(int oneByte) throws IOException(Code)(Java Doc) Methods inherited from java.lang.Object protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object object)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final public Class<? extends Object> getClass()(Code)(Java Doc) public int hashCode()(Code)(Java Doc) final public void notify()(Code)(Java Doc) final public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final public void wait(long millis, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait(long millis) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
