TAttributeCollection implements a collection for storing attribute names and values.
Besides all functionalities provided by {@link TMap}, TAttributeCollection
allows you to get and set attribute values like getting and setting
properties. For example, the following usages are all valid for a
TAttributeCollection object:
$collection->Text='text';
echo $collection->Text;
They are equivalent to the following:
$collection->add('Text','text');
echo $collection->itemAt('Text');
Note, attribute names are case-insensitive. They are converted to lower-case
in the collection storage.
public function testHasProperty()
{
$collection = new TAttributeCollection();
self::assertEquals(false, $collection->hasProperty('Property'));
$collection->Property = 'value';
self::assertEquals(true, $collection->hasProperty('Property'));
}
/**
* Returns the list of custom parameters.
* Custom parameters are name-value pairs that may subsititute translation
* place holders during rendering.
* @return TAttributeCollection the list of custom parameters
*/
public function getParameters()
{
if ($parameters = $this->getViewState('Parameters', null)) {
return $parameters;
} else {
$parameters = new TAttributeCollection();
$parameters->setCaseSensitive(true);
$this->setViewState('Parameters', $parameters, null);
return $parameters;
}
}
