Implementation of a {@link MapMessage}
org.exolab.jms.message.MapMessageImpl
This class implements the {@link javax.jms.MapMessage} interface.
A MapMessage is used to send a set of name-value pairs where names are Strings and values are Java primitive types. The entries can be accessed sequentially or randomly by name. The order of the entries is undefined. It inherits from Message and adds a map message body.
The primitive types can be read or written explicitly using methods for each type. They may also be read or written generically as objects. For instance, a call to MapMessage.setInt("foo", 6) is equivalent to MapMessage.setObject("foo", new Integer(6)). Both forms are provided because the explicit form is convenient for static programming and the object form is needed when types are not known at compile time.
When a client receives a MapMessage, it is in read-only mode. If a client attempts to write to the message at this point, a MessageNotWriteableException is thrown. If {@link #clearBody} iscalled, the message can now be both read from and written to.
Map messages support the following conversion table. The marked cases must be supported. The unmarked cases must throw a JMSException. The String to primitive conversions may throw a runtime exception if the primitives valueOf() method does not accept it as a valid String representation of the primitive.
A value written as the row type can be read as the column type.

```
Attempting to read a null value as a Java primitive type must be treated as calling the primitive's corresponding valueOf(String) conversion method with a null value. Since char does not support a String conversion, attempting to read a null value as a char must throw NullPointerException. @version $Revision: 1.1 $ $Date: 2004/11/26 01:50:43 $ @author Jim Mourikis @see javax.jms.MapMessage
