A small helper for defining conditions and matching them against some data

Use

A condition resolver, that can uses some data array and a condition array to determine, if the data array matches the conditions.

a typical single condition looks like

array(
    "cmp" => "==",
    "left" => "value1",
    "right" => "value2"
)

as "left" and "right" keys you can use a path syntax, which will try to fetch the data from the main data object.

"left" => "My.Object.some_value"
"right" => "something"

$this->setConditions() method expects an array of many conditions arrays

array(
    array( "cmp" => ... ),
    array( "cmp" => ... )
)

you can also use two operators "or" and "and".

array(
    array("or" => array(
        array( "cmp" => ... ),
        array( "cmp" => ... )
    ))
) 

the operators can also be nested, the only important thing is that an operator syntax expects that the array must contain a single key, which is "or" or "and" and the value is again a list of conditions.

another example that should work

array(
    "or" => array(
        array(
            "and" => array(
                array( condition )
                array( condition )
                array(
                    "or" => array(
                     array ( ... )
                    )
                )
            )
        )
    )
)
