  • Field Details

    • loggerN

      public static final Logger loggerN
      message logger for this class

  • Constructor Details

    • NativePhysicsObject

      protected NativePhysicsObject()
      Instantiate with no tracker and no assigned native object.

      This no-arg constructor was made explicit to avoid javadoc warnings from JDK 18+.

  • Method Details

    • countTrackers

      public static final int countTrackers()
      Count how many native objects are being tracked. This method is intended for debugging.
      Returns:
      the count (≥0)

    • dumpTrackers

      public static final void dumpTrackers()
      Dump all native-object trackers to System.out. This method is intended for debugging.

    • freeUnusedObjects

      public static final void freeUnusedObjects()
      Free any assigned native objects that are known to be unused.

    • hasAssignedNativeObject

      public final boolean hasAssignedNativeObject()
      Test whether a native object is assigned to this instance.
      Returns:
      true if one is assigned, otherwise false

    • nativeId

      public long nativeId()
      Return the ID of the assigned native object, assuming that one is assigned.
      Returns:
      the native identifier (not zero)

    • reassignNativeId

      protected final void reassignNativeId(long nativeId)
      Assign a tracked native object to this instance, unassigning (but not freeing) any previously assigned one.
      Parameters:
      nativeId - the identifier of the native object to assign (not zero)

    • setNativeId

      protected void setNativeId(long nativeId)
      Assign a tracked native object to this instance, assuming that no native object is assigned.
      Parameters:
      nativeId - the identifier of the native object to assign (not zero)

    • setNativeIdNotTracked

      protected final void setNativeIdNotTracked(long nativeId)
      Assign an untracked native object to this instance, assuming that no native object is assigned.
      Parameters:
      nativeId - the identifier of the native object to assign (not zero)

    • unassignNativeObject

      protected final void unassignNativeObject()
      Unassign (but don't free) the assigned native object, assuming that one is assigned.

    • compareTo

      public int compareTo(NativePhysicsObject other)
      Compare (by ID) with another native object.
      Specified by:
      compareTo in interface Comparable<NativePhysicsObject>
      Parameters:
      other - (not null, unaffected)
      Returns:
      0 if the objects have the same native ID; negative if this comes before other; positive if this comes after other

    • equals

      public boolean equals(Object otherObject)
      Test for ID equality with another object.
      Overrides:
      equals in class Object
      Parameters:
      otherObject - the object to compare (may be null, unaffected)
      Returns:
      true if this and otherObject have the same ID, otherwise false

    • hashCode

      public int hashCode()
      Return the hash code for this instance.

      Note: operations that alter the native ID are likely to affect the hash code as well!

      Overrides:
      hashCode in class Object
      Returns:
      a 32-bit value for use in hashing

    • toString

      public String toString()
      Represent this instance as a String.
      Overrides:
      toString in class Object
      Returns:
      a descriptive string of text (not null, not empty)
