 org.apache.commons.beanutils.MappedPropertyDescriptor
| MappedPropertyDescriptor | | public class MappedPropertyDescriptor extends PropertyDescriptor (Code) | | A MappedPropertyDescriptor describes one mapped property.
Mapped properties are multivalued properties like indexed properties
but that are accessed with a String key instead of an index.
Such property values are typically stored in a Map collection.
For this class to work properly, a mapped value must have
getter and setter methods of the form
getProperty(String key) and
setProperty(String key, Object value),
where Property must be replaced
by the name of the property.

| Constructor Summary | |
| public | MappedPropertyDescriptor(String propertyName, Class beanClass)
Constructs a MappedPropertyDescriptor for a property that follows
the standard Java convention by having getFoo and setFoo
accessor methods, with the addition of a String parameter (the key).
Thus if the argument name is "fred", it will
assume that the writer method is "setFred" and the reader method
is "getFred". | | public | MappedPropertyDescriptor(String propertyName, Class beanClass, String mappedGetterName, String mappedSetterName)
This constructor takes the name of a mapped property, and method
names for reading and writing the property.
Parameters:
propertyName - The programmatic name of the property.
Parameters:
beanClass - The Class object for the target bean. | | public | MappedPropertyDescriptor(String propertyName, Method mappedGetter, Method mappedSetter)
This constructor takes the name of a mapped property, and Method
objects for reading and writing the property.
Parameters:
propertyName - The programmatic name of the property.
Parameters:
mappedGetter - The method used for reading one ofthe property values. |

Thus if the argument name is "fred", it will
assume that the writer method is "setFred" and the reader method
is "getFred". Note that the property name should start with a lower
case character, which will be capitalized in the method names.
Parameters:
propertyName - The programmatic name of the property.
Parameters:
beanClass - The Class object for the target bean. Forexample sun.beans.OurButton.class.
exception:
IntrospectionException - if an exception occurs duringintrospection. |

Parameters:

Parameters:
mappedGetterName - The name of the method used forreading one of the property values. May be null if theproperty is write-only.
Parameters:
mappedSetterName - The name of the method used for writingone of the property values. May be null if the property isread-only.

| getMappedPropertyType | | public Class getMappedPropertyType()(Code) | | Gets the Class object for the property values.
The Java type info for the property values. Note thatthe "Class" object may describe a built-in Java type such as "int".The result may be "null" if this is a mapped property thatdoes not support non-keyed access. This is the type that will be returned by the mappedReadMethod. |
| getMappedReadMethod | | public Method getMappedReadMethod()(Code) | | Gets the method that should be used to read one of the property value.
The method that should be used to read the property value.May return null if the property can't be read. |
| getMappedWriteMethod | | public Method getMappedWriteMethod()(Code) | | Gets the method that should be used to write one of the property value.
The method that should be used to write one of the property value.May return null if the property can't be written. |
| setMappedReadMethod | | public void setMappedReadMethod(Method mappedGetter) throws IntrospectionException(Code) | | Sets the method that should be used to read one of the property value.
Parameters:
mappedGetter - The mapped getter method.
throws:
IntrospectionException - If an error occurs finding themapped property |
| setMappedWriteMethod | | public void setMappedWriteMethod(Method mappedSetter) throws IntrospectionException(Code) | | Sets the method that should be used to write the property value.
Parameters:
mappedSetter - The mapped setter method.
throws:
IntrospectionException - If an error occurs finding themapped property |
