                               InvocationTargetException

Description copied from interface: ExtendedObjectInput

Read the next data in the current input stream and set the given field of the given Object obj with this data. This method is only a convenient shortcut for reading data from the input stream and setting the value of a Field to this data without knowing its type. For example, given a field f1 of type boolean (the primitive type) and a field f2 of type int (the primitive type):

 in.readAndSetProperty(obj, f1);
 in.readAndSetProperty(obj, f2);
 

is equivalent to:

 f1.setBoolean(obj, in.readBoolean());
 f2.setInt(obj, in.readInt());
 

Specified by:

readAndSetProperty in interface ExtendedObjectInput

Parameters:

obj - The instance of the class declaring the property.

property - The property to set with the read value.

Throws:

IOException - If any I/O error occur.

JMFEncodingException - If read data isn't of expected type (ie. the type of the given property).

ClassNotFoundException - If the class of a serialized object cannot be found.

IllegalAccessException - If the property cannot be accessed.

InvocationTargetException
