Description copied from interface: IInitializableValue

Initializes this value instance through the given evaluator.

Specified by:

initialize in interface IInitializableValue

Parameters:

evaluator - the evaluator

Parameters:

evaluator - the evaluator

type - the type to initialize for

Throws:

VilException - in case that evaluating initialization expressions fails

getType

                              throws VilException

Returns the value of the slot name.

Parameters:

name - the name of the slot

Returns:

the slot value (may be null for undefined)

Throws:

VilException - if there is no such slot defined

Checks whether there is a slot with given name.

Parameters:

name - the name of the slot

Returns:

the slot

Throws:

VilException - if there is no such slot

setSlotValue

public void setSlotValue(java.lang.String name,
                         java.lang.Object value)
                  throws VilException

Parameters:

name - the name of the slot

value - the value

VilException - if there is no such slot defined

getStringValue

public java.lang.String getStringValue(IStringValueProvider.StringComparator comparator)

Description copied from interface: IStringValueProvider

Returns the string value of this object.

Specified by:

getStringValue in interface IStringValueProvider

Parameters:

comparator - if the sequence of elements, e.g., in case of collections, shall be ordered according to the comparator, null if the original sequence shall be returned

Returns:

the string value
