[Android.Runtime.Register("initCause", "(Ljava/lang/Throwable;)Ljava/lang/Throwable;", "GetInitCause_Ljava_lang_Throwable_Handler")]
public virtual Java.Lang.Throwable InitCause (Java.Lang.Throwable? cause);

[<Android.Runtime.Register("initCause", "(Ljava/lang/Throwable;)Ljava/lang/Throwable;", "GetInitCause_Ljava_lang_Throwable_Handler")>]
abstract member InitCause : Java.Lang.Throwable -> Java.Lang.Throwable
override this.InitCause : Java.Lang.Throwable -> Java.Lang.Throwable

Parameters

cause: Throwable

the cause (which is saved for later retrieval by the #getCause() method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)

Returns

Throwable

a reference to this Throwable instance.

Attributes: RegisterAttribute

Exceptions

IllegalArgumentException

if Throwable is this object.

IllegalStateException

if the cause has already been initialized.

Remarks

Initializes the cause of this throwable to the specified value. (The cause is the throwable that caused this throwable to get thrown.)

This method can be called at most once. It is generally called from within the constructor, or immediately after creating the throwable. If this throwable was created with #Throwable(Throwable) or #Throwable(String,Throwable), this method cannot be called even once.

An example of using this method on a legacy throwable type without other support for setting the cause is:

try {
                lowLevelOp();
            } catch (LowLevelException le) {
                throw (HighLevelException)
                      new HighLevelException().initCause(le); // Legacy constructor
            }

Added in 1.4.
