static <T, X extends Throwable> T	checkNotNull(T reference, Class<X> declareType, String errorMessageTemplate, Object p1)	reference为null时抛出 declareType 异常
static <T, X extends Throwable> T	checkNotNull(T reference, Class<X> declareType, String errorMessageTemplate, Object... errorMessageArgs)	reference为null时抛出 declareType 异常
static <X extends Throwable> void	checkTrue(boolean b, Class<X> declareType, String errorMessageTemplate, Object p1)	执行表达式,为false时抛出 declareType 异常

方法详细资料

checkTrue

public static <X extends Throwable> void checkTrue(boolean b,
 Class<X> declareType,
 @Nullable
 String errorMessageTemplate,
 @Nullable
 Object... errorMessageArgs)
                                            throws X

执行表达式,为false时抛出 declareType 异常

类型参数:

X - 抛出异常类型

参数:

b -

declareType - 异常类型

errorMessageTemplate - a template for the exception message should the check fail. The message is formed by replacing each %s placeholder in the template with an argument. These are matched by position - the first %s gets errorMessageArgs[0], etc. Unmatched arguments will be appended to the formatted message in square braces. Unmatched placeholders will be left as-is.

errorMessageArgs - the arguments to be substituted into the message template. Arguments are converted to strings using String.valueOf(Object).

抛出:

X

checkTrue

public static <X extends Throwable> void checkTrue(boolean b,
 Class<X> declareType,
 @Nullable
 String errorMessageTemplate,
 @Nullable
 Object p1)
                                            throws X

执行表达式,为false时抛出 declareType 异常

See checkTrue(boolean, Class, String, Object...) for details.

抛出:

X

checkNotNull

public static <T,
X extends Throwable> T checkNotNull(T reference,
 Class<X> declareType,
 @Nullable
 String errorMessageTemplate,
 @Nullable
 Object... errorMessageArgs)
                                              throws X

reference为null时抛出 declareType 异常

类型参数:

T - 对象类型

X - 抛出异常类型

参数:

reference -

declareType - 异常类型

errorMessageTemplate - a template for the exception message should the check fail. The message is formed by replacing each %s placeholder in the template with an argument.
