Method Detail

accessInstanceVariablesDirectly

public static boolean accessInstanceVariablesDirectly()

addRequestWithObserverError

public boolean addRequestWithObserverError(SNRequest request,
                                           SNResultsObserving observer,
                                           org.moe.natj.general.ptr.Ptr<NSError> error)

Adds a new analysis request to the analyzer

If addRequest is called while the file is being processed, an error will be returned.

Parameters:

request - An audio analysis request to be performed on the audio stream

observer - The object that will receive the analysis results for the supplied request. The observer is weakly retained by the analyzer.

error - On input, a pointer to an error object. If an error occurs, this pointer is set to an actual error object containing the error information. You may specify nil for this parameter if you do not want the error information.

Returns:

YES if the request was successfully added, and NO otherwise.

alloc

public static SNAudioFileAnalyzer alloc()

allocWithZone

public static SNAudioFileAnalyzer allocWithZone(org.moe.natj.general.ptr.VoidPtr zone)

analyze

public void analyze()

Analyzes the audio file synchronously

This function executes synchronously. Any errors produced during analysis will flow downstream to the request observers. This method may block for a long period of time, so be careful to ensure this call does not block UI or other important tasks.

analyzeWithCompletionHandler

public void analyzeWithCompletionHandler(SNAudioFileAnalyzer.Block_analyzeWithCompletionHandler completionHandler)

Analyzes the audio file asynchronously

This function executes asynchronously, calling the completion after the entire file has completed analysis. Any errors produced during analysis will flow downstream to the request observers. If the cancelAnalysis method is called, the completionHandler will still be called, but with didReachEndOfFile set to NO.

automaticallyNotifiesObserversForKey

public static boolean automaticallyNotifiesObserversForKey(java.lang.String key)

cancelAnalysis

public void cancelAnalysis()

Cancels any in-progress analysis of the audio file

This function executes asynchronously, and will trigger the completion handler provided in the analyzeWithCompletionHandler method after the cancellation is complete.

cancelPreviousPerformRequestsWithTarget

public static void cancelPreviousPerformRequestsWithTarget(java.lang.Object aTarget)

cancelPreviousPerformRequestsWithTargetSelectorObject

public static void cancelPreviousPerformRequestsWithTargetSelectorObject(java.lang.Object aTarget,
                                                                         org.moe.natj.objc.SEL aSelector,
                                                                         java.lang.Object anArgument)

classFallbacksForKeyedArchiver

public static NSArray<java.lang.String> classFallbacksForKeyedArchiver()

classForKeyedUnarchiver

public static org.moe.natj.objc.Class classForKeyedUnarchiver()

debugDescription_static

public static java.lang.String debugDescription_static()

description_static

public static java.lang.String description_static()

hash_static

public static long hash_static()

init

public SNAudioFileAnalyzer init()

Overrides:

init in class NSObject

initWithURLError

public SNAudioFileAnalyzer initWithURLError(NSURL url,
                                            org.moe.natj.general.ptr.Ptr<NSError> error)

Creates a new analyzer

Parameters:

url - The url for the audio file to be analyzed

error - On input, a pointer to an error object. If an error occurs, this pointer is set to an actual error object containing the error information. You may specify nil for this parameter if you do not want the error information.

instanceMethodForSelector

public static NSObject.Function_instanceMethodForSelector_ret instanceMethodForSelector(org.moe.natj.objc.SEL aSelector)

instanceMethodSignatureForSelector

public static NSMethodSignature instanceMethodSignatureForSelector(org.moe.natj.objc.SEL aSelector)

instancesRespondToSelector

public static boolean instancesRespondToSelector(org.moe.natj.objc.SEL aSelector)

keyPathsForValuesAffectingValueForKey

public static NSSet<java.lang.String> keyPathsForValuesAffectingValueForKey(java.lang.String key)

new_objc

public static SNAudioFileAnalyzer new_objc()

removeAllRequests

public void removeAllRequests()

Removes all requests from the analyzer

removeRequest

public void removeRequest(SNRequest request)

Removes an existing analysis request from the analyzer

Requests can be removed while analysis is in progress. Once the removeRequest method returns, the previously registered observer will not receive any more callbacks.

Parameters:

request - An audio analysis request to be removed

resolveClassMethod

public static boolean resolveClassMethod(org.moe.natj.objc.SEL sel)

resolveInstanceMethod

public static boolean resolveInstanceMethod(org.moe.natj.objc.SEL sel)
