UiCollection

UiCollection (UiSelector selector)

Constructs an instance as described by the selector

Public methods

getChildByDescription

UiObject getChildByDescription (UiSelector childPattern, 
                String text)

Searches for child UI element within the constraints of this UiCollection UiSelector selector. It looks for any child matching the childPattern argument that has a child UI element anywhere within its sub hierarchy that has content-description text. The returned UiObject will point at the childPattern instance that matched the search and not at the identifying child element that matched the content description.

Parameters
`childPattern`	`UiSelector`: `UiSelector` selector of the child pattern to match and return
`text`	`String`: String of the identifying child contents of of the `childPattern`

Returns
`UiObject`	`UiObject` pointing at and instance of `childPattern`

Throws
	UiObjectNotFoundException
`UiObjectNotFoundException`

getChildByInstance

UiObject getChildByInstance (UiSelector childPattern, 
                int instance)

Searches for child UI element within the constraints of this UiCollection UiSelector selector. It looks for any child matching the childPattern argument that has a child UI element anywhere within its sub hierarchy that is at the instance specified. The operation is performed only on the visible items and no scrolling is performed in this case.

Parameters
`childPattern`	`UiSelector`: `UiSelector` selector of the child pattern to match and return
`instance`	`int`: int the desired matched instance of this `childPattern`

Returns
`UiObject`	`UiObject` pointing at and instance of `childPattern`

Throws
`UiObjectNotFoundException`

getChildByText

UiObject getChildByText (UiSelector childPattern, 
                String text)

Searches for child UI element within the constraints of this UiCollection UiSelector selector. It looks for any child matching the childPattern argument that has a child UI element anywhere within its sub hierarchy that has text attribute = text. The returned UiObject will point at the childPattern instance that matched the search and not at the identifying child element that matched the text attribute.

Parameters
`childPattern`	`UiSelector`: `UiSelector` selector of the child pattern to match and return
`text`	`String`: String of the identifying child contents of of the `childPattern`

Returns
`UiObject`	`UiObject` pointing at and instance of `childPattern`

Throws
	UiObjectNotFoundException
`UiObjectNotFoundException`

getChildCount

int getChildCount (UiSelector childPattern)

Counts child UI element instances matching the childPattern argument. The method returns the number of matching UI elements that are currently visible. The count does not include items of a scrollable list that are off-screen.

Parameters
`childPattern`	`UiSelector`: a `UiSelector` that represents the matching child UI elements to count

Returns
`int`	the number of matched childPattern under the current `UiCollection`
