Record Class Dependency

java.lang.Object
java.lang.Record
org.pgcodekeeper.core.dependencieslist.Dependency
Record Components:
source - the dependent object (outgoing arrow)
target - the object providing the dependency (incoming arrow)
isStrong - true for strong dependency, false for weak; defaults to true for forward compatibility

public record Dependency(ObjectReference source, ObjectReference target, boolean isStrong) extends Record
A record representing a directed dependency between two object references.

Interpreted as: source → target (source depends on target).

A dependency can be either strong or weak:

  • Strong dependency — the source cannot function without the target (e.g., composition, inheritance, required import)
  • Weak dependency — the source may optionally use the target (e.g., observer, soft reference, suggested but not required)

This class does not validate the references nor guarantee that the dependency is acyclic — that is the responsibility of the calling code.

    • Dependency

      public Dependency(ObjectReference source, ObjectReference target)
      Canonical constructor with isStrong defaulting to true.

      This constructor is provided for backward compatibility and convenience.

      Parameters:
      source - the dependent object
      target - the object being depended upon
    • Dependency

      public Dependency(ObjectReference source, ObjectReference target, boolean isStrong)
      Creates an instance of a Dependency record class.
      Parameters:
      source - the value for the source record component
      target - the value for the target record component
      isStrong - the value for the isStrong record component
  • Method Details

    • toString

      public final String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object
    • hashCode

      public final int hashCode()
      Returns a hash code value for this object. The value is derived from the hash code of each of the record components.
      Specified by:
      hashCode in class Record
      Returns:
      a hash code value for this object
    • equals

      public final boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with '=='.
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.
    • source

      public ObjectReference source()
      Returns the value of the source record component.
      Returns:
      the value of the source record component
    • target

      public ObjectReference target()
      Returns the value of the target record component.
      Returns:
      the value of the target record component
    • isStrong

      public boolean isStrong()
      Returns the value of the isStrong record component.
      Returns:
      the value of the isStrong record component
