  • Constructor Details

    • SparseIntArray

      public SparseIntArray(int initialCapacity)
      Creates a new SparseIntArray containing no mappings that will not require any additional memory allocation to store the specified number of mappings. If you supply an initial capacity of 0, the sparse array will be initialized with a light-weight representation not requiring any additional array allocations.

  • Method Details

    • clone

      public SparseIntArray clone()
      Overrides:
      clone in class Object

    • get

      public int get(int key)
      Gets the int mapped from the specified key, or 0 if no such mapping has been made.

    • get

      public int get(int key, int valueIfKeyNotFound)
      Gets the int mapped from the specified key, or the specified value if no such mapping has been made.

    • delete

      public void delete(int key)
      Removes the mapping from the specified key, if there was any.

    • removeAt

      public void removeAt(int index)
      Removes the mapping at the given index.

    • put

      public void put(int key, int value)
      Adds a mapping from the specified key to the specified value, replacing the previous mapping from the specified key if there was one.

    • size

      public int size()
      Returns the number of key-value mappings that this SparseIntArray currently stores.

    • keyAt

      public int keyAt(int index)
      Given an index in the range 0...size()-1, returns the key from the indexth key-value mapping that this SparseIntArray stores.

      The keys corresponding to indices in ascending order are guaranteed to be in ascending order, e.g., keyAt(0) will return the smallest key and keyAt(size()-1) will return the largest key.

    • valueAt

      public int valueAt(int index)
      Given an index in the range 0...size()-1, returns the value from the indexth key-value mapping that this SparseIntArray stores.

      The values corresponding to indices in ascending order are guaranteed to be associated with keys in ascending order, e.g., valueAt(0) will return the value associated with the smallest key and valueAt(size()-1) will return the value associated with the largest key.

    • setValueAt

      public void setValueAt(int index, int value)
      Directly set the value at a particular index.

    • indexOfKey

      public int indexOfKey(int key)
      Returns the index for which keyAt(int) would return the specified key, or a negative number if the specified key is not mapped.

    • indexOfValue

      public int indexOfValue(int value)
      Returns an index for which valueAt(int) would return the specified key, or a negative number if no keys map to the specified value. Beware that this is a linear search, unlike lookups by key, and that multiple keys can map to the same value and this will find only one of them.

    • clear

      public void clear()
      Removes all key-value mappings from this SparseIntArray.

    • append

      public void append(int key, int value)
      Puts a key/value pair into the array, optimizing for the case where the key is greater than all existing keys in the array.

    • toString

      public String toString()

      This implementation composes a string by iterating over its mappings.

      Overrides:
      toString in class Object
