question: appends len chars to this buffer from the given source char array buffer starting at index off . the capacity of the buffer is increased if necessary to accommodate all len chars . the chars are converted to bytes using simple cast . concode_field_sep int len concode_elem_sep byte[] buffer concode_elem_sep long serialVersionUID concode_field_sep int byteAt concode_elem_sep void expand concode_elem_sep void setLength concode_elem_sep byte[] toByteArray concode_elem_sep void clear concode_elem_sep int length concode_elem_sep boolean isEmpty concode_elem_sep void ensureCapacity concode_elem_sep byte[] buffer concode_elem_sep boolean isFull concode_elem_sep int indexOf concode_elem_sep int indexOf concode_elem_sep int capacity
target: void function ( final CharArrayBuffer arg0 , int arg1 , int arg2 ) { if ( arg0 == null ) { return ; } append ( arg0 . buffer ( ) , arg1 , arg2 ) ; }
