BlazeDS data type mapping (Java to ActionScript)
Converting data from Java to ActionScript
An object returned from a Java method is converted from Java to ActionScript. BlazeDS also handles objects found within objects. BlazeDS implicitly handles the Java data types in the following table.

int If i < 0xF0000000 || i > 0x0FFFFFFF, the value is promoted to Number. |
|
