Class ReflectiveMetaProperty<P>

java.lang.Object

org.joda.beans.impl.BasicMetaProperty<P>

org.joda.beans.impl.reflection.ReflectiveMetaProperty<P>

Type Parameters:

P - the type of the property content

All Implemented Interfaces:

BeanQuery<P>, MetaProperty<P>

public final class ReflectiveMetaProperty<P>
extends BasicMetaProperty<P>

A meta-property implemented using a PropertyDescriptor.

The property descriptor class is part of the JDK JavaBean standard. It provides access to get and set a property on a bean.

Instances of this class should be declared as a static constant on the bean, one for each property, followed by a ReflectiveMetaBean declaration.

Method Detail

of

public static <P> ReflectiveMetaProperty<P> of(Class<? extends Bean> beanType,
                               String propertyName)

Factory to create a meta-property avoiding duplicate generics.

Type Parameters:

P - the property type

Parameters:

beanType - the bean type, not null

propertyName - the property name, not empty

Returns:

the property, not null

createProperty

public Property<P> createProperty(Bean bean)

Description copied from interface: MetaProperty

Creates a property that binds this meta-property to a specific bean.

Specified by:

createProperty in interface MetaProperty<P>

Overrides:

createProperty in class BasicMetaProperty<P>

Parameters:

bean - the bean to create the property for, not null

Returns:

the property, not null

metaBean

public MetaBean metaBean()

Description copied from interface: MetaProperty

Gets the meta-bean which owns this meta-property.

Each meta-property is fully owned by a single bean.

Returns:

the meta-bean, not null

declaringType

public Class<?> declaringType()

Description copied from interface: MetaProperty

Get the type that declares the property, represented as a Class.

Returns:

the type declaring the property, not null

propertyType

public Class<P> propertyType()

Description copied from interface: MetaProperty

Get the type of the property represented as a Class.

Returns:

the type of the property, not null

propertyGenericType

public Type propertyGenericType()

Description copied from interface: MetaProperty

Gets the generic types of the property.

This provides access to the generic type declared in the source code.

Returns:

the full generic type of the property, unmodifiable, not null

readWrite

public PropertyReadWrite readWrite()

Description copied from interface: MetaProperty

Gets whether the property is read-only, read-write or write-only.

Returns:

the property read-write type, not null

annotations

public List<Annotation> annotations()

Description copied from interface: MetaProperty

Gets the annotations of the property.

Returns:

the annotations, unmodifiable, not null

get

public P get(Bean bean)

Description copied from interface: MetaProperty

Gets the value of the property for the specified bean.

For a standard JavaBean, this is equivalent to calling getFoo() on the bean. Alternate implementations may perform any logic to obtain the value.

Parameters:

bean - the bean to query, not null

Returns:

the value of the property on the specified bean, may be null

set

public void set(Bean bean,
       Object value)

Description copied from interface: MetaProperty

Sets the value of the property on the specified bean.

The value must be of the correct type for the property. For a standard JavaBean, this is equivalent to calling setFoo() on the bean. Alternate implementations may perform any logic to change the value.

Parameters:

bean - the bean to update, not null

value - the value to set into the property on the specified bean, may be null
