FunctionMapper (Java EE 5)

用于 EL 函数名称与方法之间映射的接口。

例如，实现此接口的类可以参考标记库信息来解析映射。

public interface FunctionMapper

The interface to a map between EL function names and methods.

Classes implementing this interface may, for instance, consult tag library information to resolve the map.

Since:

JSP 2.0

public Method resolveFunction(String prefix, String localName)
将指定本地名称和前缀解析为 Java.lang.Method。如果没有找到前缀和本地名称，则返回 null。

prefix	函数前缀；如果没有前缀，则为 ""。
localName	函数的短名称
return	方法映射的结果。null 意味着没有发现任何条目。

英文文档：

resolveFunction

Method resolveFunction(String prefix,
                       String localName)

Deprecated.

Parameters:

prefix - the prefix of the function, or "" if no prefix.

localName - the short name of the function

Returns:

the result of the method mapping. Null means no entry found.
