Class ReflectiveMetaBean

java.lang.Object
  org.joda.beans.impl.reflection.ReflectiveMetaBean

All Implemented Interfaces:

MetaBean

public final class ReflectiveMetaBean
extends Object
implements MetaBean

A standard meta-bean implementation.

This is the standard implementation of a meta-bean. It requires that the bean implements Bean and has a no-arguments constructor.

of

public static <B extends Bean> ReflectiveMetaBean of(Class<B> beanClass)

Factory to create a meta-bean avoiding duplicate generics.

Type Parameters:

B - the type of the bean

Parameters:

beanClass - the bean class, not null

Returns:

the meta-bean, not null

builder

public BeanBuilder<Bean> builder()

Description copied from interface: MetaBean

Creates a bean builder that can be used to create an instance of this bean.

Specified by:

builder in interface MetaBean

Returns:

the bean builder, not null

createPropertyMap

public PropertyMap createPropertyMap(Bean bean)

Description copied from interface: MetaBean

Creates a map of properties for the specified bean.

Specified by:

createPropertyMap in interface MetaBean

Parameters:

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

Returns:

the created property map, not null

beanName

public String beanName()

Description copied from interface: MetaBean

Gets the bean name, which is normally the fully qualified class name of the bean.

Specified by:

beanName in interface MetaBean

Returns:

the name of the bean, not empty

beanType

public Class<? extends Bean> beanType()

Description copied from interface: MetaBean

Get the type of the bean represented as a Class.

Specified by:

beanType in interface MetaBean

Returns:

the type of the bean, not null

metaPropertyCount

public int metaPropertyCount()

Description copied from interface: MetaBean

Counts the number of properties.

Specified by:

metaPropertyCount in interface MetaBean

Returns:

the number of properties

metaPropertyExists

public boolean metaPropertyExists(String propertyName)

Description copied from interface: MetaBean

Checks if a property exists.

Specified by:

metaPropertyExists in interface MetaBean

Parameters:

propertyName - the property name to check, null returns false

Returns:

true if the property exists

metaProperty

public <R> MetaProperty<R> metaProperty(String propertyName)

Description copied from interface: MetaBean

Gets a meta-property by name.

The base interface throws an exception if the name is not recognised. By contrast, the DynamicMetaBean subinterface creates the property on demand.

Specified by:

metaProperty in interface MetaBean

Type Parameters:

R - the property type, optional, enabling auto-casting

Parameters:

propertyName - the property name to retrieve, not null

Returns:

the meta property, not null

metaPropertyIterable

public Iterable<MetaProperty<?>> metaPropertyIterable()

Description copied from interface: MetaBean

Gets an iterator of meta-properties.

This method returns an Iterable, which is simpler than a Map. As a result, implementations may be able to optimise, and so this method should be preferred to MetaBean.metaPropertyMap() where a choice is possible.

Specified by:

metaPropertyIterable in interface MetaBean

Returns:

the unmodifiable map of meta property objects, not null

metaPropertyMap

public Map<String,MetaProperty<?>> metaPropertyMap()

Description copied from interface: MetaBean

Gets the map of meta-properties, keyed by property name.

Where possible, use MetaBean.metaPropertyIterable() instead.

Specified by:

metaPropertyMap in interface MetaBean

Returns:

the unmodifiable map of meta property objects, not null

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Returns a string that summarises the meta-bean.

Overrides:

toString in class Object

Returns:

a summary string, not null
