Parameters:

value - the Number representing the value that should be returned

Returns:

value representing the specified double.

setMin

public void setMin(double min)

Sets the minimal value which may appear as Number specified for this description to min. Does nothing if min >= max.

Parameters:

min - minimal value appearing as Number for this description

getMin

public double getMin()

Gets the minimal Number that can be used as value for this description

Returns:

minimal value for attributes of this description

setMax

public void setMax(double max)

Sets the max value which may appear as Number specified for this description to max. Does nothing if max <=min

Parameters:

max - max value appearing as Number for this description

public double getMax()

Gets the maximal Number that can be used as value for this description

Returns:

maximal value for attributes of this description

getRange

public DoubleRange getRange()

Gets the range maintaining the number attributes of this description

Returns:

the number range of this description

addDoubleFct

public DoubleFct addDoubleFct(java.lang.String name,
                              boolean active)

Creates a new NumberFct for the given description.

Parameters:

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

Returns:

the new NumberFct for description desc

addAdvancedDoubleFct

public AdvancedDoubleFct addAdvancedDoubleFct(java.lang.String name,
                                              boolean active)

Creates a new AdvancedNumberFct for the given description.

Parameters:

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

Returns:

the new AdvancedNumberFct 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

Specified by:

canOverride in class SimpleAttDesc

fits

public boolean fits(Attribute att)

Description copied from class: AttributeDesc

Checks whether the given attribute fits this. Be aware that if this is multiple then single values will not fit. For checking whether single values fit this description without taking multiple values into account call AttributeDesc.fitsSingle(Attribute)

Overrides:

fits in class AttributeDesc

Parameters:

att -

Returns:

true, if the given att fits this

fitsSingle

public boolean fitsSingle(Attribute att)

Description copied from class: AttributeDesc

Checks whether a single attribute fits the constraints for this. Returns true, if att is a valid SpecialAttribute or if att can be used as a single value of a multiple attribute. If this is not multiple calls AttributeDesc.fits(Attribute)

Overrides:
