方法详细资料

values

public static BeanMaps[] 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 (BeanMaps c : BeanMaps.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 BeanMaps 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

toMap

public abstract Map<String,Object> toMap(Object bean)

Returns a map from bean field-value

参数:

bean - the bean object

返回:

a map

copyFromMap

public abstract void copyFromMap(Map<String,Object> sourceMap,
                                 Object targetBean)

Copies map key-value to bean object field-value

参数:

sourceMap - the source map

targetBean - the target bean

toBean

public final <T> T toBean(Map<String,Object> map,
                          Class<T> beanType)

Returns a bean object of specified Class instance, and copy map key-value to bean object field-value

参数:

map - the map

beanType - the type, must be has no args default constructor

返回:

a bean object of specified Class instance

copyFromBean

public final void copyFromBean(Object sourceBean,
                               Map<String,Object> targetMap)

Copies bean object field-value to map key-value

参数:

sourceBean - the source bean

targetMap - the target map
