Method Detail

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

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.

Specified by:

metaProperty in interface MetaBean

Type Parameters:

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

Parameters:

propertyName - the property name to retrieve, null throws NoSuchElementException

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
