Class GeneratorDependency

java.lang.Object
  rafa.dep.SimpleDependency
      rafa.math.gen.GeneratorDependency

All Implemented Interfaces:

Dependency

public class GeneratorDependency
extends SimpleDependency

Dependency of a NumberGenerator on another one. The path does not include any strategies, as the dependency of a generator on its strategy is taken for granted, and is absolute.

Method Detail

mergeWith

protected GeneratorDependency mergeWith(Dependency subDep)

Merges this dependency with another sub-dependency on a given target.

Overrides:

mergeWith in class SimpleDependency

Parameters:

subDep - The sub-dependency.

Returns:

a merged GeneratorDependency whose target is that of the sub-dependency, and whose properties have been adjusted, or null if the dependencies don't chain.

validateCircularDependency

public void validateCircularDependency()
                                throws CircularDependencyException

Checks that there will be no deadlocks due to circular dependencies, i.e. the highest index of the dependency (DEPENDENCY_INDEX + DEPENDENCY_LENGTH) is always lower that the lowest dependent index (DEPENDENT_INDEX). This way, only dependencies on values already generated are allowed.
This method should be called when an object - holding this dependency - is dependent on itself - this dependency's target -, in order to check if the self-reference is allowed or not. Besides, it should be called for every other dependent object in the circle.

Specified by:

validateCircularDependency in interface Dependency

Overrides:

validateCircularDependency in class SimpleDependency

Throws:

CircularDependencyException
