Enum Constant and Description
ABORT_POLICY 当线程池的所有线程都已经被占用时抛出 RejectedExecutionException 异常。
CALLER_RUNS_POLICY 当线程池的所有线程都已经被占用时，将由原始线程来执行任务（若原始线程已关闭将直接丢弃任务）。
DISCARD_OLDEST_POLICY 当线程池的所有线程都已经被占用时，它丢弃最古老的未处理请求，然后重试执行（若执行程序已关闭将直接丢弃任务）。
DISCARD_POLICY 当线程池的所有线程都已经被占用时，将悄悄地丢弃被拒绝的任务。

Method Detail

values

public static RejectedExecutionHandlerPolicyEnum[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (RejectedExecutionHandlerPolicyEnum c : RejectedExecutionHandlerPolicyEnum.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static RejectedExecutionHandlerPolicyEnum valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
