Filter Operations

Filter operations are used to apply specific conditions to the data being queried. They help in narrowing down the results based on various criteria. Filter operations are registered in the config/visualizations.php file under the filters key. Each filter operation class must implement the FilterOperationContract interface.

Configuration

The filter operations are configured in the config/visualizations.php file:

php

<?php

return [
    'filters' => [
         // Equality
        Equals::class,
        DoesNotEqual::class,

        // In
        In::class,
        NotIn::class,

        // Numeric
        GreaterThan::class,
        GreaterThanOrEqualTo::class,
        LessThan::class,
        LessThanOrEqualTo::class,

        // String
        Contains::class,
        DoesNotContain::class,
        EndsWith::class,
        StartsWith::class,
    ],
];

This configuration ensures that the specified filters are available for use in the application. Each filter class defines the conditions it can handle and the logic to apply those conditions to the query.
