Class IntsRef

java.lang.Object
com.graphhopper.storage.IntsRef
All Implemented Interfaces:
Comparable<IntsRef>
public final class IntsRef extends Object implements Comparable<IntsRef>
Idea and most of the code is from Lucene. But the variables are final, except for the array content.

  • Field Details

    • EMPTY

      public static final IntsRef EMPTY
      An IntsRef with an array of size 0.

    • ints

      public final int[] ints
      The contents of the IntsRef. Cannot be null.

    • offset

      public final int offset
      Offset of first valid integer.

    • length

      public final int length
      Length of used ints.

  • Constructor Details

    • IntsRef

      public IntsRef(int capacity)
      Create a IntsRef pointing to a new int array of size capacity leading to capacity*32 bits. Offset will be zero and length will be the capacity.

    • IntsRef

      public IntsRef(int[] ints, int offset, int length)
      This instance will directly reference ints w/o making a copy. ints should not be null.

  • Method Details

    • hashCode

      public int hashCode()
      Overrides:
      hashCode in class Object

    • equals

      public boolean equals(Object other)
      Overrides:
      equals in class Object

    • intsEquals

      public boolean intsEquals(IntsRef other)

    • compareTo

      public int compareTo(IntsRef other)
      Signed int order comparison
      Specified by:
      compareTo in interface Comparable<IntsRef>

    • deepCopyOf

      public static IntsRef deepCopyOf(IntsRef other)
      Creates a new IntsRef that points to a copy of the ints from other

      The returned IntsRef will have a length of other.length and an offset of zero.

    • isValid

      public boolean isValid()
      Performs internal consistency checks. Always returns true (or throws IllegalStateException)

    • toString

      public String toString()
      Overrides:
      toString in class Object

    • isEmpty

      public boolean isEmpty()
