Method Detail

values

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

Returns:

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

valueOf

public static BeanInfoCache 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

getPropertyDescriptorMap

public Map<String,PropertyDescriptor> getPropertyDescriptorMap(Class<?> beanClass,
                                                               boolean ignoreCase)

获得属性名和PropertyDescriptorMap映射

Parameters:

beanClass - Bean的类

ignoreCase - 是否忽略大小写

Returns:

属性名和PropertyDescriptorMap映射

getPropertyDescriptorMap

public Map<String,PropertyDescriptor> getPropertyDescriptorMap(Class<?> beanClass,
                                                               boolean ignoreCase,
                                                               Func0<Map<String,PropertyDescriptor>> supplier)

获得属性名和PropertyDescriptorMap映射

Parameters:

beanClass - Bean的类

ignoreCase - 是否忽略大小写

supplier - 缓存对象产生函数

Returns:

属性名和PropertyDescriptorMap映射
