public class BooleanDesc
extends SymbolDesc

Description for boolean attributes. This description does not define restrictions for its values, since there is only one attribute for true and one attribute representing false. BooleanDesc extends SymbolDesc in order to use the table function defined for symbol attributes for boolean similarity computations.

Initializes this with the given name.

Method Summary

SymbolFct	addBooleanFct(java.lang.String name, boolean active) Creates a new SymbolFct for the given description.
SymbolAttribute	addSymbol(java.lang.String value) Does nothing because you cannot add other values than true and false to a boolean description
boolean	canOverride(AttributeDesc desc) Checks whether this attribute description can override the given attribute description
Attribute	getAttribute(java.lang.Object value) Returns SymbolAttribute object representing the specified value.
SymbolAttribute	getBooleanAttribute(java.lang.Boolean value) Returns BooleanAttribute object representing the specified value.
java.lang.Integer	getIndexOf(SimpleAttribute att)
boolean	isAllowedValue(java.lang.String v) Tells you whether the specified string is an allowed value for this or not.
void	removeSymbol(java.lang.String value) Does nothing because you cannot delete a boolean value
boolean	renameValue(java.lang.String oldValue, java.lang.String newValue) Does nothing because you cannot rename a boolean value.

getBooleanAttribute

public SymbolAttribute getBooleanAttribute(java.lang.Boolean value)

Returns BooleanAttribute object representing the specified value.

Parameters:

value - the boolean representing the value that should be returned

Returns:

value representing the specified boolean.

addBooleanFct

public SymbolFct addBooleanFct(java.lang.String name,
                               boolean active)

Creates a new SymbolFct for the given description.

Parameters:

name - the name of the description for which a new function should be created

Returns:

the new SymbolFct for description desc

canOverride

public boolean canOverride(AttributeDesc desc)

Description copied from class: AttributeDesc

Checks whether this attribute description can override the given attribute description

Overrides:

canOverride in class SymbolDesc

Parameters:

desc - the description which should be overridden by this

true, if this can override the given function, false otherwise.

isAllowedValue

public boolean isAllowedValue(java.lang.String v)

Description copied from class: SymbolDesc

Overrides:

renameValue in class SymbolDesc

Parameters:

oldValue - the old value

newValue - the new value

addSymbol
