public class BasicBeanBuilder<T extends Bean>
extends Object
implements BeanBuilder<T>

Basic implementation of BeanBuilder that wraps a real bean.

This approach saves creating a temporary map, but is only suitable if the bean has a no-arg constructor and allows properties to be set.

Constructor Detail

BasicBeanBuilder

public BasicBeanBuilder(T bean)

Constructs the builder wrapping the target bean.

Parameters:

bean - the target bean, not null

Method Detail

getTargetBean

protected T getTargetBean()

Gets the target bean.

Returns:

the target bean, not null

get

public Object get(String propertyName)

Description copied from interface: BeanBuilder

Gets the value of a single property previously added to the builder.

Specified by:

get in interface BeanBuilder<T extends Bean>

Parameters:

propertyName - the property name to query, not null

Returns:

the previously set value, null if none

get

public <P> P get(MetaProperty<P> metaProperty)

Description copied from interface: BeanBuilder

Gets the value of a single property previously added to the builder.

Specified by:

get in interface BeanBuilder<T extends Bean>

Type Parameters:

P - the type of the property.

Parameters:

metaProperty - the meta-property to query, not null

Returns:

the previously set value, null if none

set

public BeanBuilder<T> set(String propertyName,
                          Object value)

Description copied from interface: BeanBuilder

Sets the value of a single property into the builder.

This will normally behave as per a Map, however it may not and as a general rule callers should only set each property once.

Specified by:

set in interface BeanBuilder<T extends Bean>

Parameters:

propertyName - the property name to set, not null

value - the property value, may be null

Returns:

this, for chaining, not null

set

public BeanBuilder<T> set(MetaProperty<?> metaProperty,
                          Object value)

Description copied from interface: BeanBuilder

Sets the value of a single property into the builder.

This will normally behave as per a Map, however it may not and as a general rule callers should only set each property once.

Specified by:

set in interface BeanBuilder<T extends Bean>

Parameters:

metaProperty - the meta-property to set, not null

value - the property value, may be null

Returns:

this, for chaining, not null

build

public T build()

Description copied from interface: BeanBuilder

Builds the bean from the state of the builder.

Once this method has been called, the builder is in an invalid state. The effect of further method calls is undetermined.

Specified by:

build in interface BeanBuilder<T extends Bean>

Returns:

the created bean, not null

validate

protected void validate(T bean)

Hook to allow a subclass to validate the bean.

Parameters:

bean - the bean to validate, not null

toString

public String toString()

Returns a string that summarises the builder.

Overrides:

toString in class Object

Returns:

a summary string, not null
