Method Summary

ListModel<java.lang.String>	getNames() Returns a list of the names of meta data entries.
V	getValue(java.lang.String aName) Returns the value of a meta data entry for the given parameter name.
java.util.Iterator<E>	iterator() Returns an iterator holding the meta data key/value pairs as Map.Entry elements.

Method Detail

getNames

ListModel<java.lang.String> getNames()

Returns a list of the names of meta data entries.

Returns:

the list of names.

getValue

V getValue(java.lang.String aName)

Returns the value of a meta data entry for the given parameter name.

Parameters:

aName - the parameter name

Returns:

the value of the meta data entry for the given name, or null if none exists

iterator

java.util.Iterator<E> iterator()
                                                                               throws ModelException

Returns an iterator holding the meta data key/value pairs as Map.Entry elements. The key/value pair is only valid for the current iteration value of the iterator and is read-only.

Specified by:

iterator in interface ListModel<E extends java.util.Map.Entry<java.lang.String,V>>

Returns:

an iterator holding key/value pairs of the meta data, never null

Throws:

ModelException - if creation of iterator fails
