方法详细资料

trace

public static void trace(Throwable e)

Trace provided Throwable to the resource entry in current context.

参数:

e - exception to record

trace

@Deprecated
public static void trace(Throwable e,
 int count)

已过时。

Trace provided Throwable to current entry in current context.

参数:

e - exception to record

count - exception count to add

traceContext

public static void traceContext(Throwable e,
 Context context)

Trace provided Throwable to current entry of given entrance context.

参数:

e - exception to record

context - target entrance context

从以下版本开始:

1.8.0

traceContext

@Deprecated
public static void traceContext(Throwable e,
 int count,
 Context context)

已过时。

Trace provided Throwable and add exception count to current entry in provided context.

参数:

e - exception to record

count - exception count to add

从以下版本开始:

1.4.2

traceEntry

public static void traceEntry(Throwable e,
 Entry entry)

Trace provided Throwable to the given resource entry.

参数:

e - exception to record

setExceptionsToTrace

@SafeVarargs
public static void setExceptionsToTrace(Class<? extends Throwable>... traceClasses)

Set exception to trace. If not set, all Exception except for BlockException will be traced.

Note that if both setExceptionsToIgnore(Class[]) and this method is set, the ExceptionsToIgnore will be of higher precedence.

参数:

traceClasses - the list of exception classes to trace.

从以下版本开始:

1.6.1

getExceptionsToTrace

public static Class<? extends Throwable>[] getExceptionsToTrace()

Get exception classes to trace.

返回:

an array of exception classes to trace.

从以下版本开始:

1.6.1

setExceptionsToIgnore

@SafeVarargs
public static void setExceptionsToIgnore(Class<? extends Throwable>... ignoreClasses)

Set exceptions to ignore. if not set, all Exception except for BlockException will be traced.

Note that if both setExceptionsToTrace(Class[]) and this method is set, the ExceptionsToIgnore will be of higher precedence.

参数:

ignoreClasses - the list of exception classes to ignore.

从以下版本开始:

1.6.1

getExceptionsToIgnore

public static Class<? extends Throwable>[] getExceptionsToIgnore()

Get exception classes to ignore.

返回:

an array of exception classes to ignore.

从以下版本开始:

1.6.1

getExceptionPredicate

public static Predicate<? extends Throwable> getExceptionPredicate()

Get exception predicate

返回:

the exception predicate.

setExceptionPredicate

public static void setExceptionPredicate(Predicate<Throwable> exceptionPredicate)

set an exception predicate which indicates the exception should be traced(return true) or ignored(return false) except for BlockException

参数:

exceptionPredicate - the exception predicate

shouldTrace

protected static boolean shouldTrace(Throwable t)

Check whether the throwable should be traced.

参数:

t - the throwable to check.

返回:

true if the throwable should be traced, else return false.
