BBjVector

Description

A BBjVector object is a single dimensional array that maintains a list of objects and dynamically sizes to fit the number of objects added.

Creation

BBjAPI > BBjVector

The BBjVector object is created through the following BBjAPI object method:

Return Value	Method
BBjVector	makeVector()

Methods of BBjVector

Return Value	Method
void	addItem(Object `item!`)
void	clear()
Object	getItem(int `index`)
void	insertItem(int `index`, Object `item!`)
Object	removeItem(int `index`)
void	setItem(int `index`, Object `item!`)
int	size()

Remarks

Any allowed type or object can be put into a BBjVector. The index is 0-based. BBjVector implements java.util.Collection and java.util.List. Therefore, all methods of these interfaces are available on BBjVector.

The rules of this Java Collection can sometimes be surprising to BBj developers. For example, the contains(Object item!) method looks for a specific object. Because of this detail, developers may have to pay extra attention to the data type of the object being added to the BBjVector, as in the Example.

Constants

None.

Example

rem ' BBjVector Example

vector! = bbjapi().makeVector()
vector!.add("hello")
vector!.add("world")
vector!.add(vector!.size())
print vector!
print vector!.contains(2); rem ' false
print vector!.contains(new Integer(2)); rem ' true
