public final class IntervalRange
extends Range

Holds IntervalAttributes for a given IntervalDesc. Each time an interval is used in a case the IntervalRange returns a reference to the corresponding IntervalAttribute object or creates a new one. SpecialAttribute are also handled for each SpecialValue used in the current project

IntervalRange

public IntervalRange(Project prj,
                     IntervalDesc d)

Initializes internal data structures.

Parameters:

prj - the project this range belongs to

d - the interval description for attributes maintained by this range

Method Detail

getIntervalValue

public IntervalAttribute getIntervalValue(Pair<java.lang.Number,java.lang.Number> interval)

Returns the IntervalAttribute associated with the given interval. Creates a new IntervalAttribute if there is no IntervalAttribute for the given interval yet.

Parameters:

interval - the value for which the corresponding IntervalAttribute should be returned

Returns:

the IntervalAttribute specified by interval

getAttribute

public Attribute getAttribute(java.lang.Object obj)

Gets the attribute associated with the specified Object obj. obj is expected to be of type Interval or String. Returns result of getIntervalValue(Pair) if obj is of type Interval, result of Project.getSpecialAttribute(String) if obj is of type SpecialAttribute, else returns null.

Specified by:

getAttribute in class Range

Parameters:

obj - representing Interval or SpecialAttribute

Returns:

SimpleAttribute that corresponds to obj, null if there is no such SimpleAttribute

update

public void update(java.util.Observable ob,
                   java.lang.Object o)

parseValue

public Attribute parseValue(java.lang.String string)

Parameters:

string - the string which should be used for parsing

Returns:

the attribute which corresponds to the given string
