=head1 NAME

Statistics::Basic::_OneVectorBase - base class objects like Mean

=head1 METHODS

=over 4

=item B<query()>

Query the value of the object.  It will return the undefined value until there's
something to calculate (or until the vector is full when
L<nofill|Statistics::Basic/nofill> is in effect).

=item B<insert()>

Insert new values into the vector. 

    $object_instance->insert( 4, 3 ); # insert a 3 and a 4

This function returns the object itself, for chaining purposes.

=item B<append()> B<ginsert()>

The growing insert inserts new elements, growing the max size of the vector to
accommodate the new elements (if necessary).

    $object_instance->ginsert( 4, 3 ); # append a 3 and a 4

This function returns the object itself, for chaining purposes.

=item B<query_size()>

The current size of the vector -- regardless of its max size (as set by
L</set_size()>).

=item B<query_vector()>

Returns the L<Statistics::Basic::Vector> object used by the computational
object.

=item B<set_size()>

Set the maximum size for the underlying L<Statistics::Basic::Vector> object.
This function requires one arguments.  

Unless L<nofill|Statistics::Basic/nofill> is set, the vector will be
filled with C<0>s (assuming the vector wouldn't otherwise be full) on the oldest
side of the vector (so an insert will push off one of the filled-zeros).

This function returns the object itself, for chaining purposes.

=item B<set_vector()>

Given a vector or array ref, this will set the contents (and size) of the vector
used for the object computations.

This function returns the object itself, for chaining purposes.

=head1 OVERLOADS

This class provides overloads.  If evaluated as a string, it will attempt to
print a pretty value for the object (or C<n/a>, see L</query()> above).  the
resulting string can be tuned, in terms of precision, see
L<ipres|Statistics::Basic/ipres> for further information.

If evaluated as a number, it will try to return the raw result of L</query()>,
possibly turning the resulting C<undef> (if applicable) into a C<0> in the
process -- note that Perl does this C<0>-izing, not the overload.

The C<eq> and C<==> operators are also overloaded, trying to do the right thing.
Also see L<toler|Statistics::Basic/toler> for further information.
