AccessibilityNodeInfo.CollectionInfo

public static final class AccessibilityNodeInfo.CollectionInfo
extends Object

java.lang.Object
↳	android.view.accessibility.AccessibilityNodeInfo.CollectionInfo

Class with information if a node is a collection. Use CollectionInfo#obtain(int, int, boolean) to get an instance. Recycling is handled by the AccessibilityNodeInfo to which this object is attached.

A collection of items has rows and columns and may be hierarchical. For example, a horizontal list is a collection with one column, as many rows as the list items, and is not hierarchical; A table is a collection with several rows, several columns, and is not hierarchical; A vertical tree is a hierarchical collection with one column and as many rows as the first level children.

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

Public constructors

CollectionInfo

public CollectionInfo (int rowCount, 
                int columnCount, 
                boolean hierarchical)

Creates a new instance.

Parameters
`rowCount`	`int`: The number of rows.
`columnCount`	`int`: The number of columns.
`hierarchical`	`boolean`: Whether the collection is hierarchical.

CollectionInfo

public CollectionInfo (int rowCount, 
                int columnCount, 
                boolean hierarchical, 
                int selectionMode)

Creates a new instance.

Parameters
`rowCount`	`int`: The number of rows.
`columnCount`	`int`: The number of columns.
`hierarchical`	`boolean`: Whether the collection is hierarchical.
`selectionMode`	`int`: The collection's selection mode.

Public methods

getColumnCount

public int getColumnCount ()

Gets the number of columns.

Returns
`int`	The column count, or -1 if count is unknown.

getRowCount

public int getRowCount ()

Gets the number of rows.

Returns
`int`	The row count, or -1 if count is unknown.

getSelectionMode

public int getSelectionMode ()

Gets the collection's selection mode.

Returns

Returns
`int`	The collection's selection mode, one of: `SELECTION_MODE_NONE` `SELECTION_MODE_SINGLE` `SELECTION_MODE_MULTIPLE`

int

The collection's selection mode, one of:

isHierarchical

public boolean isHierarchical ()

Gets if the collection is a hierarchically ordered.

Returns
`boolean`	Whether the collection is hierarchical.

obtain

public static AccessibilityNodeInfo.CollectionInfo obtain (int rowCount, 
                int columnCount, 
                boolean hierarchical, 
                int selectionMode)

Obtains a pooled instance.

In most situations object pooling is not beneficial. Create a new instance using the constructor CollectionInfo(int, int, boolean, int) instead.

Parameters
`rowCount`	`int`: The number of rows.
`columnCount`	`int`: The number of columns.
`hierarchical`	`boolean`: Whether the collection is hierarchical.
`selectionMode`	`int`: The collection's selection mode, one of: `SELECTION_MODE_NONE` `SELECTION_MODE_SINGLE` `SELECTION_MODE_MULTIPLE`

Returns
`AccessibilityNodeInfo.CollectionInfo`

obtain

public static AccessibilityNodeInfo.CollectionInfo obtain (int rowCount, 
                int columnCount, 
                boolean hierarchical)

Obtains a pooled instance.

In most situations object pooling is not beneficial. Create a new instance using the constructor CollectionInfo(int, int, boolean) instead.

Parameters
`rowCount`	`int`: The number of rows, or -1 if count is unknown.
`columnCount`	`int`: The number of columns, or -1 if count is unknown.
`hierarchical`	`boolean`: Whether the collection is hierarchical.

Returns
`AccessibilityNodeInfo.CollectionInfo`
