Method Detail

isBuildable

public boolean isBuildable()

Description copied from interface: MetaBean

Checks whether this bean is buildable or not.

A buildable bean can be constructed using MetaBean.builder(). If this method returns true then builder() must return a valid builder. If this method returns false then builder() must throw UnsupportedOperationException.

Specified by:

isBuildable in interface MetaBean

Returns:

true if this bean is buildable

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

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

propertySet

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

validate

protected void validate(Bean bean)

Validates the values of the properties.

Parameters:

bean - the bean to validate, not null

Throws:

RuntimeException - if a property is invalid

toString

public String toString()

Returns a string that summarises the meta-bean.

Overrides:

toString in class Object

Returns:

a summary string, not null
