Constructor Detail

FindIterator

public FindIterator(IConstituent<T> searched,
                    List list)

Method Detail

hasNext

public boolean hasNext()

Specified by:

hasNext in interface Iterator<IConstituent<T>>

next

public IConstituent<T> next()

Specified by:

next in interface Iterator<IConstituent<T>>

remove

public void remove()

Not supported - Will throw an UnsupportedOperationException if called.

indexOf

private int indexOf(Object elem,
                    int index)

Searches for the first occurence of the given argument, beginning the search at index, and testing for equality using the equals method.

Parameters:

elem - an object.

index - the non-negative index to start searching from.

Returns:

the index of the first occurrence of the object argument in this vector at position index or later in the vector, that is, the smallest value k such that elem.equals(elementData[k]) && (k >= index) is true; returns -1 if the object is not found. (Returns -1 if index >= the current size of this Vector.)

Throws:

IndexOutOfBoundsException - if index is negative.
