Classe: TAttributeCollection - X-Ref

TAttributeCollection class

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:
<code>
$collection->Text='text';
echo $collection->Text;
</code>
They are equivalent to the following:
<code>
$collection->add('Text','text');
echo $collection->itemAt('Text');
</code>

Note, attribute names are case-insensitive. They are converted to lower-case
in the collection storage.

__get($name) X-Ref

Returns a property value or an event handler list by property or event name.
This method overrides the parent implementation by returning
a key value if the key exists in the collection.

param: string the property name or the event name
return: mixed the property value or the event handler list

__set($name,$value) X-Ref

Sets value of a component property.
This method overrides the parent implementation by adding a new key value
to the collection.

param: string the property name or event name
param: mixed the property value or event handler

itemAt($key) X-Ref

Returns the item with the specified key.
This overrides the parent implementation by converting the key to lower case first.

param: mixed the key
return: mixed the element at the offset, null if no element is found at the offset

add($key,$value) X-Ref

Adds an item into the map.
This overrides the parent implementation by converting the key to lower case first.

param: mixed key
param: mixed value

remove($key) X-Ref

Removes an item from the map by its key.
This overrides the parent implementation by converting the key to lower case first.

param: mixed the key of the item to be removed
return: mixed the removed value, null if no such key exists.

contains($key) X-Ref

Returns whether the specified is in the map.
This overrides the parent implementation by converting the key to lower case first.

param: mixed the key
return: boolean whether the map contains an item with the specified key

hasProperty($name) X-Ref

Determines whether a property is defined.
This method overrides parent implementation by returning true
if the collection contains the named key.

param: string the property name
return: boolean whether the property is defined

canGetProperty($name) X-Ref

Determines whether a property can be read.
This method overrides parent implementation by returning true
if the collection contains the named key.

param: string the property name
return: boolean whether the property can be read

canSetProperty($name) X-Ref

Determines whether a property can be set.
This method overrides parent implementation by always returning true
because you can always add a new value to the collection.

param: string the property name
return: boolean true
