java.util.AbstractMap<K,V>
java.util.HashMap<K,V>
org.eclipse.emf.common.CommonPlugin.SimpleTargetPlatformRegistryImpl<K,V>
Type Parameters:
K - the type of the key.
V - the type of the value.
All Implemented Interfaces:
Serializable, Cloneable, Map<K,V>
Enclosing class:
CommonPlugin
public abstract static class CommonPlugin.SimpleTargetPlatformRegistryImpl<K,V> extends HashMap<K,V>
A specialized HashMap map that supports computing information from the target platform, if the PDE is available. It is abstract because the createKey(String) method must be specialized to convert each attribute's string value to a value of the map's key type.
Since:
2.14
