java.util.AbstractMap<String,Object>

cn.taketoday.bytecode.beans.BeanMap

所有已实现的接口:

Map<String,Object>

public abstract class BeanMap
extends AbstractMap<String,Object>
implements Map<String,Object>

A Map-based view of a JavaBean. The default set of keys is the union of all property names (getters or setters). An attempt to set a read-only property will be ignored, and write-only properties will be returned as null. Removal of objects is not a supported (the key set is fixed).

方法详细资料

create

public static BeanMap create(Object bean)

Helper method to create a new BeanMap. For finer control over the generated instance, use a new instance of BeanMap.Generator instead of this static method.

参数:

bean - the JavaBean underlying the map

返回:

a new BeanMap instance

newInstance

public abstract BeanMap newInstance(Object bean)

Create a new BeanMap instance using the specified bean. This is faster than using the create(java.lang.Object) static method.

参数:

bean - the JavaBean underlying the map

返回:

a new BeanMap instance

getPropertyType

public abstract Class getPropertyType(String name)

Get the type of a property.

参数:

name - the name of the JavaBean property

返回:

the type of the property, or null if the property does not exist

get

public Object get(Object key)

指定者:

get 在接口中 Map<String,Object>

覆盖:

get 在类中 AbstractMap<String,Object>

put

public Object put(String key,
 Object value)

指定者:

put 在接口中 Map<String,Object>

覆盖:

put 在类中 AbstractMap<String,Object>

get

public abstract Object get(Object bean,
 Object key)

Get the property of a bean. This allows a BeanMap to be used statically for multiple beans--the bean instance tied to the map is ignored and the bean passed to this method is used instead.

参数:

bean - the bean to query; must be compatible with the type of this BeanMap

key - must be a String

返回:

the current value, or null if there is no matching property

put

public abstract Object put(Object bean,
 Object key,
 Object value)

Set the property of a bean. This allows a BeanMap to be used statically for multiple beans--the bean instance tied to the map is ignored and the bean passed to this method is used instead.

参数:

key - must be a String

返回:

the old value, if there was one, or null

setBean

public void setBean(Object bean)

Change the underlying bean this map should use.

参数:

bean - the new JavaBean

另请参阅:

• getBean()

getBean

public Object getBean()

Return the bean currently in use by this map.

返回:

the current JavaBean

另请参阅:

• setBean(java.lang.Object)

clear

clear 在接口中 Map<String,Object>

覆盖:

clear 在类中 AbstractMap<String,Object>

覆盖:

containsKey 在类中 AbstractMap<String,Object>

指定者:

containsValue 在接口中 Map<String,Object>

覆盖:

containsValue 在类中 AbstractMap<String,Object>

size

size 在接口中 Map<String,Object>

覆盖:

size 在类中 AbstractMap<String,Object>
