枚举常量概要

枚举常量

枚举常量	说明
IMMEDIATE	In immediate mode, expressions are compiled as soon as possible (usually after 1 interpreted run).
MIXED	In mixed mode, expression evaluation silently switches between interpreted and compiled over time.
OFF	The compiler is switched off; this is the default.

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.

values

public static SpelCompilerMode[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

返回:

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.)

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 - if this enum class has no constant with the specified name

NullPointerException - 如果参数为空值
