Constructor Detail

InterfaceFilterMappings

public InterfaceFilterMappings(Element node)

Creates a new Interface Filter Mappings. This consists of one or more IfMaps. The IfMaps configuration is defined in the node.

Parameters:

node - Element which specifies the IfMaps configuration.

Method Detail

initIfMaps

private void initIfMaps(Element node)
                 throws InterfaceFilterMappingsException

Initializes the If-Maps and checks wether two identical entries were defined.

Parameters:

node -

Throws:

InterfaceFilterMappingsException

doubleEntry

private boolean doubleEntry(IfMap map)

Checks wether the specified map has the same direction and interface as another one.

Parameters:

map - The map entry to check.

Returns:

True if the map entry is identical to another one. False otherwise.

matchChain

public String matchChain(String interf,
                         String direction)

Matches interface and direction to the corresponding chain. Checks if a defined interface-filter-mapping corresponds to the given interface and direction.

Parameters:

interf - The interface to match.

direction - The direction to match.

Returns:

Chain Name of the chain corresponding to the given interface and direction. Null if no match was found.

getMappings

public Vector getMappings()

Return the interface filter mappings (if-map)

Returns:

Returns the mappings.

setMappings

public void setMappings(Vector mappings)

Sets new interface filter mappings (if-map)

Parameters:

mappings - The mappings to set.

toString
