Method Detail

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
Overrides:: metaProperty in class BasicMetaBean

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

metaPropertyGet

protected MetaProperty<?> metaPropertyGet(String propertyName)

Gets the meta-property by name.

This implementation returns null, and must be overridden in subclasses.

Parameters:: propertyName - the property name, not null
Returns:: the meta-property, null if not found

propertyGet

protected Object propertyGet(Bean bean,
                             String propertyName,
                             boolean quiet)

Gets the value of the property.

Parameters:: bean - the bean to query, not null; propertyName - the property name, not null; quiet - true to return null if unable to read
Returns:: the value of the property, may be null
Throws:: NoSuchElementException - if the property name is invalid

protected void propertySet(Bean bean,
                           String propertyName,
                           Object value,
                           boolean quiet)

Sets the value of the property.

Parameters:: bean - the bean to update, not null; propertyName - the property name, not null; value - the value of the property, may be null; quiet - true to take no action if unable to write
Throws:: NoSuchElementException - if the property name is invalid
