=head1 SUBROUTINES

=over

=item new(spreadsheet => <object>, (id => <string> | name => <string> | uri => <string>));

Creates a new instance of a Worksheet object. You would not normally
call this directly, you would obtain it from the
Spreadsheet->open_worksheet routine.

 spreadsheet: The parent object that represents the collection of worksheets.
 id: The id of the worksheet (0, 1, 2 etc).
 name: The name of the worksheet (as shown on the tab).
 uri: The worksheet ID extracted from the overall URI.

Only one of id/name/uri should be specified and this API will derive the others
as necessary.

=item worksheet_id()

Returns the worksheet id.

=item worksheet_name()

Returns the worksheet name or title.

=item worksheet_uri()

Returns the worksheet URL (URL);

=item properties(what<string>);

Returns the specific properties of this worksheet, such as the title or sheet id (sheetId).

=item col(range<range>, values<arrayref>);

Positional args consist of:

=over

=item * C<<range>>: A range representing a column.

=item * C<<arrayref<str>>>: An array of strings of column values.

=back

Gets or sets the column values.

 $ws->col('A', [1, 2, 3]);
 $values = $ws->col('A');

Note: the Google API is called immediately, so this is the easiest but least efficient way of getting/setting spreadsheet values.

Returns the values for the specified column.

=item cols(cols, values); Positional args consist of:

=over

=item C<<arrayref<range>>>: An array of ranges that represent columns.

=item C<<arrayref<arrayref<string>>>>: An optional array of values to set the columns to.

=back

Gets or sets a group of columns, see note for 'col' above.

 $ws->cols(['A', 2, 'Id'], [[1, 2, 3, 4], [5], [6, 7]]);
 $values = $ws->cols(['A', 2, 'Id']);

Returns the values for the specified columns.

=item row(range<range>, values<arrayref<string>>);

Same as 'col' above, but operates on a row.

=item rows(rows<arrayref<range>>, values<arrayref<arrayref<string>>>)

Same as 'cols' above, but operates on rows.

=item cell(col<range>, row<range>|range<range>), value<string>);

Same as above, but operates on a cell.

=item enable_header_row(enable<boolean>)

This turns on/off the header row so that column headings can be used as keys to tied hashes. See header_row.

=item header_row(refresh<boolean>)

Returns an array of values in the first row that act as simple
headers for the columns. The values are cached in the worksheet
so that multiple calls will only invoke the API once, unless you
pass a true value to the routine to refresh them.

This is used internally to check for indexed column names such as
'Id', 'Name' or 'Address' etc. It may be of limited use externally.

This will only work on simple headers that don't use fancy formatting
spread over multiple merged cells/rows.

=item enable_header_col(enable<boolean>)

This turns on/off the header row so that column headings can be used as keys to tied hashes. See header_col.

You must pass C<i really want to do this> to turn it on. This is because you may have a worksheet with thousands of rows that end up being 'headers'. This is less of an issue with header row.

=item header_col(refresh<boolean>)

A less practical version of header_row, uses the first column to
label each row. Since this is cached, if the spreadsheet is large,
this can potentially use a lot of memory. Therefore, you must call
enable_header_col first, with C<i really want to do this> value, to obtain these column values.

=item name_value_pairs(name_col<range>, value_col<range>);

A utility to convert two columns into a simple hash.

 name_col: A range pointing to the keys of the hash.
 value_col: A range pointing to the values of the hash.

A spreadsheet with the values:

 Name    Value
 Fred    1
 Charlie 2

...will return the hash:

 Fred    => 1,
 Charlie => 2,

This allows you to store and retrieve a hash with little muss or fuss.

=item tie_ranges(ranges<array<hash|<string>>>...);

Ties the given ranges into a tied range group. Specify
either a 'key => range<range>' or a plain <range<string>>.

 $tied = $ws->tie_ranges({id => 'A2'}, 'B2', 'A5:B6');
 $tied->{id} = [['1001']];
 $tied->{B2} = [['Herb Ellis']];
 $tied->{A5:B6} = [[1, 2], [3, 4]];
 tied(%$tied)->submit_values();

If you need to represent the range as anything but a string, you must
specify the key=>range format ({id => [1, 2]} or {id => {col => 1, row => 1}}).

=item tie_cols(ranges<array<range>>...);

Same as tie_ranges (above), but ties Range::Col objects. Specify
range strings, or column headings to represent the columns.

 $tied = $ws->tie_cols({id => 'A'}, 'Name');
 $tied->{id} = [1001, 1002, 1003];
 $tied->{Name} = ['Herb Ellis', 'Bela Fleck', 'Freddie Mercury'];
 tied(%$tied)->submit_values();

=item tie_rows(ranges<array<range>>...);

Same as tie_cols (above), but ties Range::Row objects.

 $tied = $ws->tie_rows({herb => 2}, {bela => 3});
 $tied->{herb} = ['Herb Ellis'];
 $tied->{bela} = ['Bela Fleck'];
 tied(%$tied)->submit_values();

To use row 'headings' as ranges (assuming 'Herb Ellis' is in column 1),
you must call 'enable_header_col' to enable the row headers first
(see below).

=item tie_cells(ranges<array<range>>...);

Same as above, but ties Range::Cell objects.

 $tied = $ws->tie_cells(qw({id => A2}, B2));
 $tied->{id} = 1001;
 $tied->{B2} = 'Herb Ellis';
 tied(%$tied)->submit_values();

=item tie(ranges<hash>);

Ties the given 'key => range' pairs into a tied range group, and sets
the default worksheet, for any new keys later added, to this worksheet.

 $tied = $ws->tie(id => $range_cell);
 $tied->{id} = 1001;
 $teid->{B2} = 'Herb Ellis'; # autocreated for this worksheet.
 tied(%$tied)->submit_values();

New keys that are added later are assumed to address cells if there is
no ':' (A1), or a general range if a ':' is found (A1:B2). It is better
to explicitly set all the ranges you expect to use on the call to 'tie'
rather than auto-creating the ranges later to avoid unexpected behaviour.

See also L<Google::RestApi::SheetsApi4::Spreadsheet> C<tie>.

=item submit_requests(%args)

Submits any outstanding requests (API batchRequests) for this worksheet.
%args are any args to be passed to the RestApi's 'api' routine (content,
params etc).

=item range(range<range>);

Returns a Range object or one of its subclasses (Col, Row etc) representing the passed range. If you specify a range that
represents a column (A:A), you will get back a Range::Col object. To guaranty a particular subclass returned, use the below routines (range_col,
range_row, etc).

=item range_col(range<range>);

Returns a L<Google::RestApi::SheetsApi4::Range::Col> object representing the passed range. If you pass a non-column range, your script will die.

=item range_row(range<range>);

Returns a L<Google::RestApi::SheetsApi4::Range::Row> object representing the passed range.

=item range_cell(range<range>);

Returns a L<Google::RestApi::SheetsApi4::Range::Cell> object representing the passed range.

=item range_all();

Returns a L<Google::RestApi::SheetsApi4::Range::All> object that represents the whole worksheet. Caution: this class has not been fully tested.

=item range_group_cols

Returns a L<Google::RestApi::SheetsApi4::RangeGroup> object that represents a group of columns.

=item range_group_rows(ranges<arrayref>);

Returns a L<Google::RestApi::SheetsApi4::RangeGroup> object that represents a group of rows.

=item range_group_cells(ranges<arrayref>);

Returns a L<Google::RestApi::SheetsApi4::RangeGroup> object that represents a group of cells.

=item range_group(ranges<arrayref>);

Returns a L<Google::RestApi::SheetsApi4::RangeGroup> object that represents a group of arbitrary ranges.

=item api(%args);

A passthrough to the parent Spreadsheet object's 'api' routine.

=item sheets_api();

Returns the SheetsApi4 object.

=item spreadsheet();

Returns the parent Spreadsheet object.

=item spreadsheet_id();

Returns the parent Spreadsheet id.
