A field expression is either the name of a public field or a getter method with parentheses
of the {@link DataStream}'s underlying type. A dot can be used to drill

@param fields
One or more field expressions on which the state of the {@link DataStream} operators will be
partitioned.

<code>-1</code> is returned.
<p>
There is no restriction on the value of <code>start</code>. If it
is negative, it has the same effect as if it were zero: the entire
<code>CharSequence</code> may be searched. If it is greater than
the length of <code>cs</code>, it has the same effect as if it were
equal to the length of <code>cs</code>: <code>-1</code> is returned.
<p>All indices are specified in <code>char</code> values
(Unicode code units).
@param cs the {@code CharSequence} to be processed, not null
@param searchChar the char to be searched for
@param start the start index, negative starts at the string start
@return the index where the search char was found, -1 if not found
@since 3.6 updated to behave more like <code>String</code> | [
