Constructs a new rule base with given name.

Parameters:

newName - The new value for the property.

Method Detail

getId

public int getId()

Returns the technical identifier (e.g. within a database).

Returns:

the ID

getName

public final String getName()

Returns the name of this rule base.

Returns:

the name property

public String toString()

Overrides:

toString in class Object

toString

public String toString(boolean withRules)

Returns a textual representation of the rule base
