All Implemented Interfaces:
Serializable, Comparable<SpelCompilerMode>, Constable

public enum SpelCompilerMode extends Enum<SpelCompilerMode>
Captures the possible configuration settings for a compiler that can be used when evaluating expressions.

  • Enum Constant Details

    • OFF

      public static final SpelCompilerMode OFF
      The compiler is switched off; this is the default.

      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.

    • values

      public static SpelCompilerMode[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      an array containing the constants of this enum class, in the order they are declared
    • valueOf

      public static SpelCompilerMode valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
      name - the name of the enum constant to be returned.
      the enum constant with the specified name
      IllegalArgumentException - if this enum class has no constant with the specified name
      NullPointerException - if the argument is null
