Instance pooling is likely to be a good idea for fixed size buffers and definitely a good idea for java 1.4 direct buffers (since their allocation/deallication is more expensive than regular java objects). author:    teck Method Summary public static  TCByteBuffer copyAndWrap(byte[] buf)      public static  TCByteBuffer[] getFixedSizedInstancesForLength(boolean direct, int length)      Get enough fixed sized TCByteBuffer instances to contain the given number of bytes Parameters:   direct - True to hint that the buffers should be direct buffers (ie. public static  TCByteBuffer getInstance(boolean direct, int size)      Get a single variable sized TCByteBuffer instance Note: These are not pooled (yet) Parameters:   size - The desired minimum capacity of the buffer. public static  void returnBuffer(TCByteBuffer buf)      public static  void returnBuffers(TCByteBuffer buffers)      public static  TCByteBuffer wrap(byte[] buf)      Method Detail copyAndWrap public static TCByteBuffer copyAndWrap(byte[] buf)(Code) getFixedSizedInstancesForLength public static TCByteBuffer[] getFixedSizedInstancesForLength(boolean direct, int length)(Code) Get enough fixed sized TCByteBuffer instances to contain the given number of bytes Parameters:   direct - True to hint that the buffers should be direct buffers (ie. not on the Java heap). Direct bufferswill never be returned if this parameter is false. Direct buffers may or MAY NOT returned if the parameteris true. The returned buffers may be a mix of direct and non-direct Parameters:   length - an array of TCByteBuffer instances (with length always >= 1). The limit of the last buffer may be less thenit's capacity to adjust for the given length getInstance public static TCByteBuffer getInstance(boolean direct, int size)(Code) Get a single variable sized TCByteBuffer instance Note: These are not pooled (yet) Parameters:   size - The desired minimum capacity of the buffer. The actual capacity may be higher. The buffer's limit willbe equal to it's capacity. Parameters:   direct - True to hint that the buffer should be a direct buffer (ie. not on the Java heap). A direct bufferwill never be returned if this parameter is false. A direct buffer may or MAY NOT returned if the parameteris true TODO :: Make this the only interface and make it return fixed size buffer also make sure onlyfixedBufferSize gets to the pool back. returnBuffer public static void returnBuffer(TCByteBuffer buf)(Code) returnBuffers public static void returnBuffers(TCByteBuffer buffers)(Code) wrap public static TCByteBuffer wrap(byte[] buf)(Code) Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
