Class ImplicitObjectELResolver.EnumeratedMap<K,​V>

  • All Implemented Interfaces:
    java.util.Map<K,​V>
    Enclosing class:
    ImplicitObjectELResolver
    private abstract static class ImplicitObjectELResolver.EnumeratedMap<K,​V>
extends java.lang.Object
implements java.util.Map<K,​V>

    This is a Map implementation driven by a data source that only provides an enumeration of keys and a getValue(key) method. This class must be subclassed to implement those methods.

    Some of the methods may incur a performance penalty that involves enumerating the entire data source. In these cases, the Map will try to save the results of that enumeration, but only if the underlying data source is immutable.
