Debug.GetInstanceCounts Method

Definition

Overloads

Name Description
GetInstanceCounts(IList<Class>)

Counts the number of instances of the specified classes.

GetInstanceCounts(IList<Class>, Boolean)

Counts the number of instances of the specified classes.

GetInstanceCounts(IList<Class>)

Counts the number of instances of the specified classes.

[Android.Runtime.Register("getInstanceCounts", "(Ljava/util/List;)[J", "", ApiSince=36)]
public static long[] GetInstanceCounts(System.Collections.Generic.IList<Java.Lang.Class> classes);
[<Android.Runtime.Register("getInstanceCounts", "(Ljava/util/List;)[J", "", ApiSince=36)>]
static member GetInstanceCounts : System.Collections.Generic.IList<Java.Lang.Class> -> int64[]

Parameters

classes
IList<Class>

An array of Class objects representing the classes to count instances of. Must not be null.

Returns

Int64[]

An array of long values, where each element corresponds to the number of instances of the class at the same index in the classes list. The returned array will have the same length as the input classes array. If the system is under memory pressure and unable to allocate the return array a empty array will be returned.

Attributes

Remarks

Counts the number of instances of the specified classes.

<b>Warning:</b> This operation can be expensive, as it may involve traversing portions of the Java heap. It is primarily intended for debugging purposes and should not be used in performance-critical code.

It's intended to help developers identify object leaks or to validate the number of instances of a specific class during development.

It is the caller's responsibility to do GC if they don't want unreachable objects to get counted.

GetInstanceCounts(IList<Class>, Boolean)

Counts the number of instances of the specified classes.

[Android.Runtime.Register("getInstanceCounts", "(Ljava/util/List;Z)[J", "", ApiSince=36)]
public static long[] GetInstanceCounts(System.Collections.Generic.IList<Java.Lang.Class> classes, bool includeAssignable);
[<Android.Runtime.Register("getInstanceCounts", "(Ljava/util/List;Z)[J", "", ApiSince=36)>]
static member GetInstanceCounts : System.Collections.Generic.IList<Java.Lang.Class> * bool -> int64[]

Parameters

classes
IList<Class>

An array of Class objects representing the classes to count instances of. Must not be null.

includeAssignable
Boolean

if true, any instance whose class is assignable to cls, as defined by Class#isAssignableFrom, is counted. If false, only instances whose class is equal to cls are counted.

Returns

Int64[]

An array of long values, where each element corresponds to the number of instances of the class at the same index in the classes list. The returned array will have the same length as the input classes array. If the system is under memory pressure and unable to allocate the return array a empty array will be returned.
