Class BooleanArrayList

    • Constructor Detail

      • BooleanArrayList

        public BooleanArrayList()
        Constructs an empty list.
      • BooleanArrayList

        public BooleanArrayList(boolean[] elements)
        Constructs a list containing the specified elements. The initial size and capacity of the list is the length of the array. WARNING: For efficiency reasons and to keep memory usage low, the array is not copied. So if subsequently you modify the specified array directly via the [] operator, be sure you know what you're doing.
        Parameters:
        elements - the array to be backed by the the constructed list
      • BooleanArrayList

        public BooleanArrayList(int initialCapacity)
        Constructs an empty list with the specified initial capacity.
        Parameters:
        initialCapacity - the number of elements the receiver can hold without auto-expanding itself by allocating new internal memory.
    • Method Detail

      • add

        public void add(boolean element)
        Appends the specified element to the end of this list.
        Overrides:
        add in class AbstractBooleanList
        Parameters:
        element - element to be appended to this list.
      • beforeInsert

        public void beforeInsert(int index,                boolean element)
        Inserts the specified element before the specified position into the receiver. Shifts the element currently at that position (if any) and any subsequent elements to the right.
        Overrides:
        beforeInsert in class AbstractBooleanList
        Parameters:
        index - index before which the specified element is to be inserted (must be in [0,size]).
        element - element to be inserted.
        Throws:
        IndexOutOfBoundsException - index is out of range (index < 0 || index > size()).
      • copy

        public BooleanArrayList copy()
        Returns a deep copy of the receiver; uses clone() and casts the result.
        Returns:
        a deep copy of the receiver.
      • countSortFromTo

        public void countSortFromTo(int from,                   int to)
        Sorts the specified range of the receiver into ascending numerical order (false < true). The sorting algorithm is a count sort. This algorithm offers guaranteed O(n) performance without auxiliary memory.
        Parameters:
        from - the index of the first element (inclusive) to be sorted.
        to - the index of the last element (inclusive) to be sorted.
      • elements

        public boolean[] elements()
        Returns the elements currently stored, including invalid elements between size and capacity, if any. WARNING: For efficiency reasons and to keep memory usage low, the array is not copied. So if subsequently you modify the returned array directly via the [] operator, be sure you know what you're doing.
        Overrides:
        elements in class AbstractBooleanList
        Returns:
        the elements currently stored.
      • elements

        public AbstractBooleanList elements(boolean[] elements)
        Sets the receiver's elements to be the specified array (not a copy of it). The size and capacity of the list is the length of the array. WARNING: For efficiency reasons and to keep memory usage low, the array is not copied. So if subsequently you modify the specified array directly via the [] operator, be sure you know what you're doing.
        Overrides:
        elements in class AbstractBooleanList
        Parameters:
        elements - the new elements to be stored.
        Returns:
        the receiver itself.
      • ensureCapacity

        public void ensureCapacity(int minCapacity)

        Specified by:
        ensureCapacity in class AbstractBooleanList
        Parameters:
        minCapacity - the desired minimum capacity.
      • equals

        public boolean equals(Object otherObj)
        Compares the specified Object with the receiver. Returns true if and only if the specified Object is also an ArrayList of the same type, both Lists have the same size, and all corresponding pairs of elements in the two Lists are identical. In other words, two Lists are defined to be equal if they contain the same elements in the same order.
        Overrides:

        Parameters:
        otherObj - the Object to be compared for equality with the receiver.

        Overrides:
        forEach in class AbstractBooleanList
        Parameters:
        procedure - the procedure to be applied. Stops iteration if the procedure returns false, otherwise continues.
        Returns:
        false if the procedure stopped before all elements where iterated over, true otherwise.
