Enum SpelCompilerMode

Enum Constant Detail

• 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.

Method Detail

• values

  public static SpelCompilerMode[] 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 (SpelCompilerMode c : SpelCompilerMode.values())
      System.out.println(c);
  

  Returns:

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

• valueOf

  public static SpelCompilerMode 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
