Examples of org.apache.commons.io.output.ByteArrayOutputStream

org.apache.commons.io.output.ByteArrayOutputStream
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.
This is an alternative implementation of the java.io.ByteArrayOutputStream class. The original implementation only allocates 32 bytes at the beginning. As this class is designed for heavy duty it starts at 1024 bytes. In contrast to the original it doesn't reallocate the whole memory block but allocates additional buffers. This way no buffers need to be garbage collected and the contents don't have to be copied to the new buffer. This class is designed to behave exactly like the original. The only exception is the deprecated toString(int) method that has been ignored. @author Jeremias Maerki @version $Id: ByteArrayOutputStream.java 369075 2006-01-14 18:23:42Z scolebourne $
