NAME
Data::Grid::Table - A table implementation for Data::Grid
VERSION
Version 0.01_01
SYNOPSIS
my $grid = Data::Grid->parse('arbitrary.csv');
# Just take the first one, since a CSV will only have one table.
my ($table) = $grid->tables;
while (my $row = $table->next) {
# do some stuff
}
# or
while (my $row = <$table>) {
# ...
}
# or
my @rows = $table->rows;
# or
my @rows = @$table;
METHODS
next
Retrieves the next row in the table or undef
when it reaches the end. This method "must be overridden" by a driver subclass. The iteration operator <
> is also overloaded for table objects, so you can use it like this:
while (my $row = <$table>) { ...
first
Returns the first row in the table, and is equivalent to calling "rewind" and then "next".
rewind
Sets the table's cursor back to the first row. Returns the previous position, beginning at zero. This method must be overridden by a driver subclass.
rows
Retrieves an array of rows all at once, or if taken in scalar context, an array reference. This method overloads the array dereferencing operator @{}
, so you can use it like this:
my @rows = @$table;
columns
width
Gets the width, in columns, of the table.
height
Gets the height, in rows, of the table. Careful, for drivers that only do sequential access, this means iterating over the whole set, so you might as well.
as_string
Serializes the table into a string and returns the result. Currently unimplemented.
as_data_table
Returns a new Data::Table object for compatibility.
