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
