# some private subroutines here are called by RangeGroup, so think of RangeGroup as

# "private range routine called here!"

# there are different ways to specify ranges. this came about by merging different
# ideas from different spreadsheet implementations.

=head1 NAME

Google::RestApi::SheetsApi4::Range - Represents a range in a Worksheet.

=head1 DESCRIPTION

A Range object that represents a range in a remote spreadsheet. These are
normally short-lived objects used to set up and execute a remote action.
Keep in mind that the remote spreadsheet can be concurrently updated by
many people, so a compromise must always be reached between holding a copy
of the local cell values versus the number of network calls to the Google
API to keep the values current.

A range can be specified in whatever way is most convenient.

For ranges:

 * A1 notation: A1:B2
 * Hash: [ { col => (A|1), row => 1 }, { col => (B|2), row => 2 } ]
 * Array: [ [ (A|1), 1 ], [ (B|2), 2 ] ]

For columns:

 * A1 notation: A or A:A
 * Hash: { col => (A|1) }
 * Array: [ A|1 ]

For rows:

 * A1 notation: 1 or 1:1
 * Hash: { row => 1 }
 * Array: [ <false>, 1 ]

For cells:

 * A1 notation: A1
 * Hash: { col => (A|1), row => 1 }
 * Array: [ (A|1), 1 ]

See the description and synopsis at L<Google::RestApi::SheetsApi4>.

=head1 SUBROUTINES

=over

=item new(%args);

Creates a new range object for the given worksheet.

%args consists of:

=over

=item * C<worksheet> <Worksheet>: The parent Worksheet object for this range.

=item * C<range> <range>: The range for this object, either A1 notation, hash {col => x, row => x} or array [col, row].

=item * C<dim> <col|row>: The major dimension for this range, either 'col' or 'row', defaults to 'row'.

=back

You would not normally call this directly, you'd use Worksheet::range* methods to create the range object for you. It is recommended and safer to use
the Worksheet's methods to create ranges.

=item api(%args);

Calls the parent Worksheet's 'api' routine with the range added into the URI or content appropriately. This then get's passed to the
Spreadsheet's C<api> routine where the spreadsheet ID is tacked on to the URI. This then gets passed to the SheetsApi4's C<api>
routine where the Sheets endpoint is tacked on to the URI. This then gets passed to RestApi's api routine for actual execution.

You would not normally call this directly unless you were making a Google API call not currently supported by this API framework.

=item clear();

Clears the values using Google API's 'A1:clear' call.

=item refresh_values();

Immediately refreshes and returns the values from the spreadsheet.

=item values(values => <arrayref>, %args);

Immediately gets or sets the values using Google API's 'get' or 'update'.

 values: The array ref of cells to update.

'args' are passed to the SheetsApi4's 'api' routine so you may add
extra arguments to the 'params' (such as C<valueInputOption>) or 'content' as necessary.

=item batch_values(values => <arrayref>);

Gets or sets the queued batch values that will be sent to Google API
at a later time. Call 'submit_values' to send them later.

 values: The array ref of cells to update.

=item submit_values(%args);

Sends the previously queued batch values to Google API, if any.

'args' are passed to the SheetsApi4's 'api' routine so you may add
extra arguments to the 'params' or 'content' as necessary.

=item submit_requests(%args);

Sends the previously queued requests (formatting, sheet properties etc)
to Google API, if any.

'args' are passed to the SheetsApi4's 'api' routine so you may add
extra arguments to the 'params' or 'content' as necessary.

=item normalize_named();

If this is a 'named range', get the named range property from the
spreadsheet and set this object's real range that the named range
represents.

=item named();

Returns the 'named range' for this range, if any.

=item range();

Returns the A1 notation for this range.

=item range_to_hash();

Returns the hash representation for this range (e.g. {col => 1, row => 1}). Passing $RANGE_EXPANDED
will always return a double cell notations: [{col => 1, row => 1}, {col => 1, row => 1}].

=item range_to_array();

Returns the array representation for this range (e.g. [1, 1]). Passing $RANGE_EXPANDED
will always return a double cell notations: [[ 1, 1 ], [ 1, 1]].

=item range_to_index();

Returns the index hash representation for this range, used for formatting
requests etc. You would not normally need to call this yourself.

=item range_to_dimension();

Returns the dimension hash representation for this range, used for
insert requests etc. You would not normally need to call this yourself.

=item offset(col => <int>, row => <int>, top => <int>, left => <int>, bottom => <int>, right => <int>);

Returns a new range object offset from this range.

 col: Optionally offset the new range by this many columns.
 row: Optionally offset the new range by this many rows.
 top: Optionally offset the new range with the new top.
 left: Optionally offset the new range with the new left.
 bottom: Optionally offset the new range with the new bottom.
 right: Optionally offset the new range with the new right.

=item offsets(range<Range>);

Returns the offsets of this range from the given range in an
array (top, left, bottom, right).

=item iterator(%args);

Returns an iterator for this range. Any 'args' are passed to the
'new' routine for the iterator.

=item is_other_inside(range<Range>);

Returns a true value if the given range fits entirely inside this range.

=item share_values(range<Range>);

Share the cell values between this range and the passed range.

Normally ranges are short-lived, throw-away objects used to interact
with the Google API. Range objects work independently and don't
share any common storage of cells. No attempt is made to share a
common, local grid that mirrors what's in the remote spreadsheet.
The spreadsheet is a shared resource that can be updated concurrently
by multiple users, so attempting to mirror it locally is a waste of
time unless some kind of listener is provided that can be used to
syncronize the remote updates with the local copy (which Google doesn't).

However, for some cases, like iterators, we can set up ranges to
share values between them for a short time in order to reduce the
number of network calls to the Google API while you iterate over
the cells. When the iterated cell values are updated, the parent
range's value is also updated.

So far, this is the only use-case I can see for sharing the cell
grid between ranges.

=item dimension();

Returns this range's major dimension (col|row).

=item has_values();

Returns a true value if this range's values have been set either via
'values' or 'batch_values' routines.

=item worksheet();

Returns the parent Worksheet object.

=item worksheet_name();

Returns the parent Worksheet name.

=item worksheet_id();

Returns the parent Worksheet ID.

=item spreadsheet();

Returns the parent Spreadsheet object.

=item spreadsheet_id();

Returns the parent Spreadsheet ID.
