ResourceLeakDetector

@Deprecated
public ResourceLeakDetector(java.lang.Class<?> resourceType)

已过时。 use ResourceLeakDetectorFactory.newResourceLeakDetector(Class, int, long).

ResourceLeakDetector

@Deprecated
public ResourceLeakDetector(java.lang.String resourceType)

已过时。 use ResourceLeakDetectorFactory.newResourceLeakDetector(Class, int, long).

ResourceLeakDetector

@Deprecated
public ResourceLeakDetector(java.lang.Class<?> resourceType,
                                         int samplingInterval,
                                         long maxActive)

已过时。 Use ResourceLeakDetector(Class, int).

This should not be used directly by users of ResourceLeakDetector. Please use ResourceLeakDetectorFactory.newResourceLeakDetector(Class) or ResourceLeakDetectorFactory.newResourceLeakDetector(Class, int, long)

参数:

maxActive - This is deprecated and will be ignored.

ResourceLeakDetector

public ResourceLeakDetector(java.lang.Class<?> resourceType,
                            int samplingInterval)

This should not be used directly by users of ResourceLeakDetector. Please use ResourceLeakDetectorFactory.newResourceLeakDetector(Class) or ResourceLeakDetectorFactory.newResourceLeakDetector(Class, int, long)

ResourceLeakDetector

@Deprecated
public ResourceLeakDetector(java.lang.String resourceType,
                                         int samplingInterval,
                                         long maxActive)

已过时。 use ResourceLeakDetectorFactory.newResourceLeakDetector(Class, int, long).

参数:

maxActive - This is deprecated and will be ignored.

方法详细资料

setEnabled

@Deprecated
public static void setEnabled(boolean enabled)

已过时。 Use setLevel(Level) instead.

isEnabled

public static boolean isEnabled()

Returns true if resource leak detection is enabled.

setLevel

public static void setLevel(ResourceLeakDetector.Level level)

Sets the resource leak detection level.

getLevel

public static ResourceLeakDetector.Level getLevel()

Returns the current resource leak detection level.

open

@Deprecated
public final ResourceLeak open(T obj)

已过时。 use track(Object)

Creates a new ResourceLeak which is expected to be closed via ResourceLeak.close() when the related resource is deallocated.

返回:

the ResourceLeak or null

track

public final ResourceLeakTracker<T> track(T obj)

Creates a new ResourceLeakTracker which is expected to be closed via ResourceLeakTracker.close(Object) when the related resource is deallocated.

返回:

the ResourceLeakTracker or null

trackForcibly

public ResourceLeakTracker<T> trackForcibly(T obj)

Creates a new ResourceLeakTracker which is expected to be closed via ResourceLeakTracker.close(Object) when the related resource is deallocated. Unlike track(Object), this method always returns a tracker, regardless of the detection settings.

返回:

the ResourceLeakTracker

needReport

protected boolean needReport()

When the return value is true, reportTracedLeak(java.lang.String, java.lang.String) and reportUntracedLeak(java.lang.String) will be called once a leak is detected, otherwise not.

返回:

true to enable leak reporting.

reportTracedLeak

protected void reportTracedLeak(java.lang.String resourceType,
                                java.lang.String records)

This method is called when a traced leak is detected. It can be overridden for tracking how many times leaks have been detected.

reportUntracedLeak

protected void reportUntracedLeak(java.lang.String resourceType)

This method is called when an untraced leak is detected. It can be overridden for tracking how many times leaks have been detected.

reportInstancesLeak

@Deprecated
protected void reportInstancesLeak(java.lang.String resourceType)

已过时。 This method will no longer be invoked by ResourceLeakDetector.

getInitialHint

protected java.lang.Object getInitialHint(java.lang.String resourceType)

Create a hint object to be attached to an object tracked by this record. Similar to the additional information supplied to ResourceLeakTracker.record(Object), will be printed alongside the stack trace of the creation of the resource.

setLeakListener

public void setLeakListener(ResourceLeakDetector.LeakListener leakListener)

Set leak listener. Previous listener will be replaced.

addExclusions

public static void addExclusions(java.lang.Class clz,
                                 java.lang.String... methodNames)
