Class BasicMetaBean

java.lang.Object
  org.joda.beans.impl.BasicMetaBean

All Implemented Interfaces:

MetaBean

Direct Known Subclasses:

DirectMetaBean

public abstract class BasicMetaBean
extends Object
implements MetaBean

Basic implementation of MetaBean.

BasicMetaBean

public BasicMetaBean()

createPropertyMap

public PropertyMap createPropertyMap(Bean bean)

Description copied from interface: MetaBean

Creates a map of properties for the specified bean.

This allows the entire set of properties of the bean to be exposed as a Map. The map is keyed by the property name and has Property instances as values. Call PropertyMap.flatten() to convert the map to hold the actual values from the 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.

This is primarily used for human-readable output.

Specified by:

beanName in interface MetaBean

Returns:

the name of the bean, not empty

metaPropertyCount

public int metaPropertyCount()

Description copied from interface: MetaBean

Counts the number of properties.

Each meta-bean manages a single bean with a known set of properties. This method returns the count 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.

Each meta-bean manages a single bean with a known set of properties. This method checks whether there is a property with the specified name.

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.

Each meta-bean manages a single bean with a known set of properties. This method returns the property with the specified 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

toString

public String toString()

Returns a string that summarises the meta-bean.

Overrides:

toString in class Object

Returns:

a summary string, not null
