| Inheritance | TypeAliases  Object |
This helper is used in a ioc container (ObjectFactory) to map the type class of an object.
Example :
import system.data.Iterator ;
import system.ioc.TypeAliases ;
var aliases:TypeAliases = new TypeAliases() ;
aliases.put( "DropShadowFilter" , "flash.filters.DropShadowFilter" ) ;
aliases.put( "ObjectFactory" , "system.ioc.ObjectFactory" ) ;
aliases.put( "HashMap" , "system.data.maps.HashMap" ) ;
trace("-------- aliases.containsAlias('DropShadowFilter')") ;
trace( aliases.containsAlias('DropShadowFilter') ) ;
trace( aliases.containsAlias('noAlias') ) ;
trace("-------- aliases.containsValue()") ;
trace( aliases.containsValue('system.ioc.ObjectFactory') ) ;
trace( aliases.containsValue('unknow') ) ;
trace("-------- aliases.getAliases()") ;
trace( aliases.getAliases() ) ;
trace("-------- aliases.getValue('ObjectFactory')") ;
trace( aliases.getValue("ObjectFactory") ) ;
trace("-------- aliases.getValues()") ;
trace( aliases.getValues() ) ;
trace("-------- iterator") ;
var it:Iterator = aliases.iterator() ;
while( it.hasNext() )
{
var next:String = it.next() as String ;
var key:String = it.key() as String ;
trace( aliases + " alias : '" + key + "' -> value : '" + next + "'" ) ;
}
trace("-------- clear and isEmpty") ;
trace( aliases.isEmpty() ) ;
aliases.clear() ;
trace( aliases.isEmpty() ) ;

import system.ioc.TypeAliases ;
var aliases:TypeAliases = new TypeAliases() ;
aliases.put( "DropShadowFilter" , "flash.filters.DropShadowFilter" ) ;
aliases.put( "BlurFilter" , "flash.filters.BlurFilter" ) ;
trace( aliases.getAliases() ) ;

alias:String — The alias name, this expression not must be null and not empty or the method return false.
| |
value:String — The value of the alias type, this expression not must be null and not empty or the method return false.
|
Boolean — true if the alias can be registered.
