david-garcia / value-object example snippets





// Example for StringValue
use DavidGarcia\ValueObject\Primitive\StringValue;


StringValue::create('qwerty');


$stringValue1 = StringValue::create('qwerty', true);
$stringValue2 = StringValue::create('qwerty', true);

if ($stringValue1 === $stringValue2) {
    // TRUE
    // It's the same object, so it goes inside this conditional
}

$stringValue3 = StringValue::create('qwerty');
$stringValue4 = StringValue::create('qwerty');

if ($stringValue3 === $stringValue4) {
    // FALSE
    // Although they have the same value, the system has created two different objects
}


// `NullValue` does not expect any argument
$nullValue = NullValue::create();


$stringValue = StringValue::create('qwerty');
$stringValue->getValue(); // Returns 'qwerty'


$stringValue = StringValue::create('qwerty');
(string) $stringValue; // Returns 'qwerty'


$stringValue1 = StringValue::create('qwerty', true);
$stringValue2 = StringValue::create('qwerty', true);

if ($stringValue1->equals($stringValue2)) {
    // TRUE
    // We ignore the fact that is a cached object, as we compare the value
}

$stringValue3 = StringValue::create('qwerty');
$stringValue4 = StringValue::create('qwerty');

if ($stringValue3->equals($stringValue4)) {
    // TRUE
    // We have a match for the values, so even if we handle two different objects,
    // their values are equal
}
