枚举 SpelCompilerMode

枚举常量详细资料

• OFF

  public static final SpelCompilerMode OFF

  The compiler is switched off; this is the default.

• IMMEDIATE

  public static final SpelCompilerMode IMMEDIATE

  In immediate mode, expressions are compiled as soon as possible (usually after 1 interpreted run). If a compiled expression fails it will throw an exception to the caller.

• MIXED

  public static final SpelCompilerMode MIXED

  In mixed mode, expression evaluation silently switches between interpreted and compiled over time. After a number of runs the expression gets compiled. If it later fails (possibly due to inferred type information changing) then that will be caught internally and the system switches back to interpreted mode. It may subsequently compile it again later.

方法详细资料

• values

  public static SpelCompilerMode[] values()

  按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示:

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

  返回:

  按照声明该枚举类型的常量的顺序返回的包含这些常量的数组

• valueOf

  public static SpelCompilerMode valueOf​(String name)

  返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)

  参数:

  name - 要返回的枚举常量的名称。

  返回:

  返回带有指定名称的枚举常量

  抛出:

  IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量

  NullPointerException - 如果参数为空值
