NAME

Test::DBChanges::ChangeSet - set of changes to DB tables

VERSION

version 1.0.0

SYNOPSIS

    my $dbchanges = Test::DBChanges::Pg->new({
        dbh => $dbh,
        source_names => [qw(things ledger)],
    });

    # later:
    my $changeset = $dbchanges->changeset_for_code(sub { do_something($dbh) });

    for my $row ($changeset->changes_for_source('things')->inserted_rows->@*) {
       # $row is a hashref with the inserted data
    }

DESCRIPTION

Instances of this class are instantiated by a Test::DBChanges::* class. They contain all the data needed to construct hashrefs or objects for each inserted / updated / deleted row in all tracked tables.

ATTRIBUTES

changed_tables

List of strings, the names of the tables that saw changes.

METHODS

changes_for_source

    my $changes = $changeset->changes_for_source('things');

Given a source name (that was in the source_names attribute of the DBChanges instance that build this object), returns a Test::DBChanges::TableChangeSet instance containing the changes for the corresponding table.

If you pass in a wrong (or just not tracked) name, you get undef.
