Interface Dependency

All Known Subinterfaces:
Modifier, Value
All Known Implementing Classes:
AbstractDependency, AbstractModifier, DependencyDependent, MappingOperationModifier, MappingOperationModifier.SpecialValue, OperationModifier, StaticValue, ValueImpl
public interface Dependency
A class with values that values of other classes depend on. A class with values depending on the implementing class should implement Dependent, and all dependents should be added to the class implementing this interface with addDependent(Dependent) or addDependents(Collection). The implementation of these methods must check for cyclic dependencies and throw IllegalArgumentException if one would be caused by the operation.

  • Method Details

    • getDependents

      Collection<Dependent> getDependents()
      Returns:
      all Dependents that depend on this class

    • invalidateDependents

      void invalidateDependents()
      Calls Dependent.invalidate() on all Dependents of this class.

    • addDependent

      boolean addDependent(Dependent dependent)
      Register a Dependent that depends on this class. The method must check for cyclic dependencies and throw IllegalArgumentException if one is detected.
      Parameters:
      dependent - Dependent that depends on this class
      Returns:
      true if the registered Dependents changed as a result of this operation
      Throws:
      IllegalArgumentException - if this operation would cause a cyclic dependency

    • addDependents

      boolean addDependents(Collection<? extends Dependent> dependencies)
      Register Dependents that depends on this class. The method must check for cyclic dependencies and throw IllegalArgumentException if one is detected.
      Parameters:
      dependencies - Dependencies that depend on this class
      Returns:
      true if the registered Dependents changed as a result of this operation
      Throws:
      IllegalArgumentException - if this operation would cause a cyclic dependency

    • removeDependent

      boolean removeDependent(Dependent dependent)
      Parameters:
      dependent - Dependent to be removed
      Returns:
      true if the registered Dependents changed as a result of this operation

    • removeDependents

      boolean removeDependents(Collection<? extends Dependent> dependents)
      Parameters:
      dependents - Dependents to be removed
      Returns:
      true if the registered Dependents changed as a result of this operation

    • containsDependent

      boolean containsDependent(Dependent dependent)
      Parameters:
      dependent - Dependent to be checked for
      Returns:
      true if the specified Dependent is registered to this class

    • containsDependents

      boolean containsDependents(Collection<? extends Dependent> dependents)
      Parameters:
      dependents - Dependents to be checked for
      Returns:
      true if all the specified Dependents are registered to this class

    • containsDependentRecursive

      boolean containsDependentRecursive(Dependent dependent)
      Checks if the specified Dependent is registered to this class or any of its dependents that also implement dependent, recursively. In practice any dependent that depends on this class, directly or indirectly, would cause this method to return true.
      Parameters:
      dependent - Dependent to be checked for
      Returns:
      true if the specified Dependent is registered to this class or any of its dependents that also implement dependent, recursively

    • containsDependentsRecursive

      boolean containsDependentsRecursive(Collection<? extends Dependent> dependents)
      Checks if all the specified Dependents are registered to this class or any of its dependencies that also implement dependent, recursively. In practice any collection of dependencies that depend on this class, directly or indirectly, would cause this method to return true.
      Parameters:
      dependents - Dependencies to be checked for
      Returns:
      true if the specified Dependencies are registered to this class or any of its dependencies that also implement dependent, recursively

    • dependentStream

      Stream<Dependent> dependentStream()
      Returns:
      Stream of all Dependents that are registered to this class

    • recursiveDependentStream

      Stream<Dependent> recursiveDependentStream()
      Returns:
      Stream of all Dependents that are registered to this class or any of its dependents that also implement dependency, recursively
