Method Detail

internKey

protected java.lang.String internKey(java.lang.Object key)
                              throws java.lang.ClassCastException

Template method for calculating an internal key representation. The default implementation just performs a cast. This method may throw a class cast exception if the provided key is not an instance of the key type.

Overrides:

internKey in class ArrayBackedMap<java.lang.String,V>

Throws:

java.lang.ClassCastException - if the provided key is not of a suitable class.

areEqual

protected boolean areEqual(java.lang.String key1,
                           java.lang.String key2)

Template method for comparing two keys for equality.

Overrides:

areEqual in class ArrayBackedMap<java.lang.String,V>
