DBIx::Class::Cursor(3) User Contributed Perl Documentation DBIx::Class::Cursor(3)NAME
DBIx::Class::Cursor - Abstract object representing a query cursor on a resultset.
SYNOPSIS
my $cursor = $schema->resultset('CD')->cursor();
# raw values off the database handle in resultset columns/select order
my @next_cd_column_values = $cursor->next;
# list of all raw values as arrayrefs
my @all_cds_column_values = $cursor->all;
DESCRIPTION
A Cursor represents a query cursor on a DBIx::Class::ResultSet object. It allows for traversing the result set with "next", retrieving all
results with "all" and resetting the cursor with "reset".
Usually, you would use the cursor methods built into DBIx::Class::ResultSet to traverse it. See "next" in DBIx::Class::ResultSet, "reset"
in DBIx::Class::ResultSet and "all" in DBIx::Class::ResultSet for more information.
METHODS
new
Virtual method. Returns a new DBIx::Class::Cursor object.
next
Virtual method. Advances the cursor to the next row. Returns an array of column values (the result of "fetchrow_array" in DBI method).
reset
Virtual method. Resets the cursor to the beginning.
all
Virtual method. Returns all rows in the DBIx::Class::ResultSet.
