assertKeyValidity

protected abstract void assertKeyValidity(java.lang.Object key)
                                   throws java.lang.ClassCastException,
                                          java.lang.NullPointerException

Throws:: java.lang.ClassCastException - if the key is of an inappropriate type for this map; java.lang.NullPointerException - if the key is null and this map does not not permit null keys

getInternalValue

protected abstract java.lang.Object getInternalValue(java.lang.Object value)
                                              throws java.lang.IllegalArgumentException,

Unwrap the value to the the internal value that will be stored in the map.

Parameters:: value - the value to unwrap
Returns:: the unwrapped value
Throws:: java.lang.ClassCastException - if the class of the specified value prevents it from being stored in this map; java.lang.IllegalArgumentException - if some aspect of this key prevents it from being stored in this map; java.lang.NullPointerException - this map does not permit null values, and the specified value is null
