NAME

Data::Grid::Row - Row implementation for Data::Grid::Table

VERSION

Version 0.06

SYNOPSIS

    # CSV files are themselves only a single table, so the list
    # context assignment here takes the first and only one.
    my ($table) = Data::Grid->parse('foo.csv')->tables;

    while (my $row = $table->next) {
        my @cells = $row->cells;
        # or
        @cells = @$row;

        # or, if column names were supplied somehow:

        my %cells = $row->as_hash;
        # or
        %cells = %$row;
    }

METHODS

table

Retrieve the Data::Grid::Table object to which this row belongs. Alias for "parent" in Data::Grid::Container.

cells [$FLATTEN]

Retrieve the cells from the row, as an array in list context or arrayref in scalar context. The array dereferencing operator @{} is also overloaded and works like this:

    my @cells = @$row;

width

Returns the width of the row in columns. This is the same as scalar @{$row->cells}.

as_hash [$FLATTEN]

If the table has a heading or its columns were designated in the constructor or with "columns" in Data::Grid::Table, this method will return the row as key-value pairs in list context and a HASH reference in scalar context. If there is no column spec, this method will generate dummy column names starting from 1, like col1, col2, etc. It will also fill in the blanks if the column spec is shorter than the actual row. If the column spec is longer, the overhang will be populated with undefs. As well it is worth noting that duplicate keys will be clobbered with the rightmost value at this time, though that behaviour may change.

as_string

Returns the row as CSV, quoted where necessary, minus the newline.
