AMF java与as3类转换对应

ActionScript type (AMF 3)	Deserialization to Java	Supported Java type binding
Array (dense)	java.util.List	java.util.Collection, Object[ ] (native array) If the type is an interface, it is mapped to the following interface implementations: List becomes ArrayList SortedSet becomes TreeSet Set becomes HashSet Collection becomes ArrayList A new instance of a custom Collection implementation is bound to that type.
Array (sparse)	java.util.Map	java.util.Map
Boolean String of "true" or"false"	java.lang.Boolean	Boolean, boolean, String
flash.utils.ByteArray	byte []
flash.utils.IExternalizable	java.io.Externalizable
Date	java.util.Date (formatted for Coordinated Universal Time (UTC))	java.util.Date, java.util.Calendar, java.sql.Timestamp, java.sql.Time, java.sql.Date
int/uint	java.lang.Integer	java.lang.Double, java.lang.Long, java.lang.Float, java.lang.Integer, java.lang.Short, java.lang.Byte, java.math.BigDecimal, java.math.BigInteger, String, primitive types of double, long, float, int, short, byte
null	null	primitives
Number	java.lang.Double	java.lang.Double, java.lang.Long, java.lang.Float, java.lang.Integer, java.lang.Short, java.lang.Byte, java.math.BigDecimal, java.math.BigInteger, String, 0 (zero) if null is sent, primitive types of double, long, float, int, short, byte
Object (generic)	java.util.Map	If a Map interface is specified, creates a new java.util.HashMap for java.util.Map and a new java.util.TreeMap for java.util.SortedMap.
String	java.lang.String	java.lang.String, java.lang.Boolean, java.lang.Number, java.math.BigInteger, java.math.BigDecimal, char[], any primitive number type
typed Object	typed Object When you use[RemoteClass]metadata tag that specifies remote class name. Bean type must have a public no args constructor.	typed Object
undefined	null	null for object, default values for primitives
XML	org.w3c.dom.Document	org.w3c.dom.Document
XMLDocument (legacy XML type)	org.w3c.dom.Document	org.w3c.dom.Document You can enable legacy XML support for the XMLDocument type on any channel defined in the services-config.xml file. This setting is important only for sending data from the server back to the client; it controls how org.w3c.dom.Document instances are sent to ActionScript.

Primitive values cannot be set to null in Java. When passing Boolean and Number values from the
