Method Detail

getSize

public int getSize()

Returns the number of components in this list.

This method is identical to size, which implements the List interface defined in the 1.2 Collections framework. This method exists in conjunction with setSize so that size is identifiable as a JavaBean property.

Returns:

the number of components in this list

See Also:

size()

getElementAt

public Object getElementAt(int index)

Returns the component at the specified index.

Parameters:

index - an index into this list

Returns:

the component at the specified index

Throws:

ArrayIndexOutOfBoundsException - if the index is negative or greater than the current size of this list

See Also:

#get(int)

size

public int size()

Returns the number of components in this list.

Returns:

the number of components in this list

See Also:

Vector#size()

isEmpty

public boolean isEmpty()

Tests whether this list has any components.

Returns:

true if and only if this list has no components, that is, its size is zero; false otherwise

See Also:

Vector#isEmpty()

contains

public boolean contains(Object elem)

Tests whether the specified object is a component in this list.

Parameters:

elem - an object

Returns:

true if the specified object is the same as a component in this list

See Also:

Vector#contains(Object)

indexOf

public int indexOf(Object elem)

Searches for the first occurrence of elem.

Parameters:

elem - an object

Returns:

the index of the first occurrence of the argument in this list; returns -1 if the object is not found

See Also:

Vector#indexOf(Object)

lastIndexOf

public int lastIndexOf(Object elem)

Returns the index of the last occurrence of elem.

Parameters:

elem - the desired component

Returns:

the index of the last occurrence of elem in the list; returns -1 if the object is not found

See Also:

Vector#lastIndexOf(Object)

set

public void set(int index,
                Object obj)

Sets the component at the specified index of this list to be the specified object. The previous component at that position is discarded.

Throws an ArrayIndexOutOfBoundsException if the index is invalid.

Parameters:

obj - what the component is to be set to

index - the specified index

See Also:

set(int,Object), Vector#setElementAt(Object,int)

remove

public void remove(int index)

Deletes the component at the specified index.

Throws an ArrayIndexOutOfBoundsException if the index is invalid.

Parameters:

index - the index of the object to remove

See Also:

remove(int), Vector#removeElementAt(int)

add

public void add(int index,
                Object obj)

Inserts the specified object as a component in this list at the specified index.

Throws an ArrayIndexOutOfBoundsException if the index is invalid.

Parameters:

obj - the component to insert

index - where to insert the new component

Throws:

ArrayIndexOutOfBoundsException - if the index was invalid

See Also:

add(int,Object), Vector#insertElementAt(Object,int)

add

public void add(Object obj)

Adds the specified component to the end of this list.

Parameters:

obj - the component to be added

See Also:

Vector#addElement(Object)

remove

public boolean remove(Object obj)

Removes the first (lowest-indexed) occurrence of the argument from this list.

Parameters:

obj - the component to be removed

Returns:

true if the argument was a component of this list; false otherwise

See Also:

Vector#removeElement(Object)

clear

public void clear()

Removes all components from this list and sets its size to zero.

See Also:

Vector#removeAllElements()

toString

public String toString()

Returns a string that displays and identifies this object's properties.

Overrides:

toString in class Object

Returns:

a String representation of this object

addAll

public void addAll(Collection<Object> c)
