From class java.lang.Object

Object	clone () Creates and returns a copy of this `Object` .
boolean	equals ( Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize () Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class <?>	getClass () Returns the unique instance of `Class` that represents this object's class.
int	hashCode () Returns an integer hash code for this object.
final void	notify () Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll () Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString () Returns a string containing a concise, human-readable description of this object.
final void	wait () Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait (long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait (long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

Public Methods

public static boolean isObjectSelected ( Object object)

Added in API level 1

Filters objects against the ANDROID_OBJECT_FILTER environment variable. This environment variable can filter objects based on their class name and attribute values.

Here is the syntax for ANDROID_OBJECT_FILTER :

ClassName@attribute1=value1@attribute2=value2...

Examples:

Select TextView instances: TextView
Select TextView instances of text "Loading" and bottom offset of 22: TextView@text=Loading.*@bottom=22

The class name and the values are regular expressions.

This class is useful for debugging and logging purpose:

         if (DEBUG) {
   if (DebugUtils.isObjectSelected(childView) && LOGV_ENABLED) {
     Log.v(TAG, "Object " + childView + " logged!");
   }
 }

NOTE : This method is very expensive as it relies heavily on regular expressions and reflection. Calls to this method should always be stripped out of the release binaries and avoided as much as possible in debug mode.

Parameters

object	any object to match against the ANDROID_OBJECT_FILTER environement variable

Returns

true if object is selected by the ANDROID_OBJECT_FILTER environment variable, false otherwise
