 package elemental.util;

A lightweight array of numbers.

 
 public interface ArrayOfNumber {
  
Returns a new array that is the concatenation of this array and values. This method does not mutate the current array.
 
   ArrayOfNumber concat(ArrayOfNumber values);

  
Gets the value at a given index. If an undefined or non-numeric value exists at the given index, a type-conversion error will occur in hosted mode and unpredictable behavior may occur in web mode.

Parameters:
index the index to be retrieved
Returns:
the value at the given index
 
   double get(int index);

  
Inserts a new element into the array at the specified index. Note: If index >= the length of the array, the element will be appended to the end. Also if the index is negative, the element will be inserted starting from the end of the array.
   
   void insert(int indexdouble value);

  
Returns true if the length of the array is zero.

Returns:
true when length is zero
 
   boolean isEmpty();

  
Check that the specified index has been initialized to a valid value.
 
   boolean isSet(int index);

  
Convert each element of the array to a String and join them with a comma separator. The value returned from this method may vary between browsers based on how JavaScript values are converted into strings.
 
   String join();

  
Convert each element of the array to a String and join them with a comma separator. The value returned from this method may vary between browsers based on how JavaScript values are converted into strings.
 
   String join(String separator);

  
Gets the length of the array.

Returns:
the array length
 
   int length();

  
Returns the last value of the array;

Returns:
the last value
 
   double peek();

  
Remove and return the element from the end of the array.

Returns:
the removed value
 
   double pop();

  
Pushes the given number onto the end of the array.
  void push(double value);

  
Removes the element at the specified index.
  void removeByIndex(int index);

  
Sets the value value at a given index. If the index is out of bounds, the value will still be set. The array's length will be updated to encompass the bounds implied by the added value.

Parameters:
index the index to be set
value the value to be stored
  void set(int indexdouble value);

  
Reset the length of the array.

Parameters:
length the new length of the array
  void setLength(int length);

  
Shifts the first value off the array.

Returns:
the shifted value
  double shift();

  
Sorts the contents of the array in ascending order.
  void sort();

  
Sorts the contents of the Array based on the CanCompareNumber.

Parameters:
comparator
  void sort(CanCompareNumber comparator);

  
Removes the specified number of elements starting at index and returns the removed elements.
  ArrayOfNumber splice(int indexint count);

  
Shifts a value onto the beginning of the array.

Parameters:
value the value to the stored
  void unshift(double value);
