getAttribute

protected abstract java.lang.Object getAttribute(java.lang.String key)

Hook method that needs to be implemented by concrete subclasses. Gets a value associated with a key.

Parameters:

key - the key to lookup

Returns:

the associated value, or null if none

setAttribute

protected abstract void setAttribute(java.lang.String key,
                java.lang.Object value)

Hook method that needs to be implemented by concrete subclasses. Puts a key-value pair in the map, overwriting any possible earlier value associated with the same key.

Parameters:

key - the key to associate the value with

value - the value to associate with the key

removeAttribute

protected abstract void removeAttribute(java.lang.String key)

Hook method that needs to be implemented by concrete subclasses. Removes a key and its associated value from the map.

Parameters:

key - the key to remove

getAttributeNames

protected abstract java.util.Iterator getAttributeNames()

Hook method that needs to be implemented by concrete subclasses. Returns an enumeration listing all keys known to the map.

Returns:

the key enumeration
