Constructor Detail

NumberGenerator

public NumberGenerator(java.lang.String name,
                       GeneratorStrategy strategy)
                throws CircularDependencyException

Throws:

CircularDependencyException

Method Detail

generate

public void generate()
              throws java.lang.Exception

Description copied from interface: INumberGenerator

Performs an iteration of value generation.

Specified by:

generate in interface INumberGenerator

Throws:

java.lang.Exception

getValue

public java.lang.Number getValue(int index)
                          throws java.lang.Exception

Specified by:

getValue in interface INumberGenerator

Parameters:

index - The value index. If negative, begin at the end.

Returns:

The value. If index doesn't exist, values are generated until it does.

Throws:

java.lang.Exception

public java.util.List<java.lang.Number> getValues()

Specified by:

getValues in interface INumberGenerator

Returns:

Returns the values.

getStrategy

public GeneratorStrategy getStrategy()

Returns:

setStrategy

public void setStrategy(GeneratorStrategy strategy)
                 throws CircularDependencyException

Parameters:

strategy -

Throws:

CircularDependencyException

reset

public void reset()

Description copied from interface: INumberGenerator

Resets the generator to initial values.

Specified by:

reset in interface INumberGenerator

propertyChange

public void propertyChange(java.beans.PropertyChangeEvent evt)

Specified by:

propertyChange in interface java.beans.PropertyChangeListener

getDependencies

public java.util.Collection<Dependency> getDependencies(java.lang.Object dep)

Description copied from interface: Dependent

Gets detailed information about the dependencies of this object on a given one.

Specified by:

getDependencies in interface Dependent

Parameters:

dep - the required object. If null, all of the dependencies will be returned.

Returns:

a collection of Dependency objects pointing to the same object (target), or null if there is no dependency on that object.
