ResizableByteArrayOutputStream

open class ResizableByteArrayOutputStream : ByteArrayOutputStream

An extension of java.io.ByteArrayOutputStream that:

has public org.springframework.util.ResizableByteArrayOutputStream#grow(int) and org.springframework.util.ResizableByteArrayOutputStream#resize(int) methods to get more control over the size of the internal buffer
has a higher initial capacity (256) by default

As of 4.2, this class has been superseded by FastByteArrayOutputStream for Spring's internal use where no assignability to ByteArrayOutputStream is needed (since FastByteArrayOutputStream is more efficient with buffer resize management but doesn't extend the standard ByteArrayOutputStream).
