public CodeStream putByteArray ( final byte [ ] b , final int offset , final int length ) { ensureCapacity ( length ) ; if ( b != null ) { System . arraycopy ( b , offset , _data , _length , length ) ; } _length += length ; return this ; }
puts an array of bytes into this byte stream . the byte stream is automatically enlarged if necessary .
