Method Detail

getAttribute

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

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

setAttribute

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

Hooks 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.

removeAttribute

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

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

getAttributeNames

protected abstract java.util.Iterator<java.lang.String> getAttributeNames()

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