Class BufferingBeanBuilder<T extends Bean>

java.lang.Object

org.joda.beans.impl.BufferingBeanBuilder<T>

Type Parameters:

T - the bean type

All Implemented Interfaces:

BeanBuilder<T>

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

Implementation of BeanBuilder that buffers data in a local map.

This is useful for cases where the builder data might be manipulated before the final build. The buffer can be directly mutated.

Constructor Detail

BufferingBeanBuilder

public BufferingBeanBuilder(MetaBean metaBean)

Constructs the builder wrapping the target bean.

Parameters:

metaBean - the target meta-bean, not null

Method Detail

of

public static BufferingBeanBuilder<?> of(MetaBean metaBean)

Constructs the builder wrapping the target bean.

Parameters:

metaBean - the target meta-bean, not null

Returns:

a new untyped builder, not null

getMetaBean

public MetaBean getMetaBean()

Gets the meta-beans.

Returns:

the meta-bean, not null

getBuffer

public ConcurrentMap<MetaProperty<?>,Object> getBuffer()

Gets the buffer holding the state of the builder.

The buffer may be mutated.

Returns:

the mutable buffer, not null

get

public Object get(String propertyName)

Gets the buffered value associated with the specified property name.

Specified by:

get in interface BeanBuilder<T extends Bean>

Parameters:

propertyName - the property name, not null

Returns:

the current value in the builder, null if not found or value is null

get

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

Gets the buffered value associated with the specified property name.

Specified by:

get in interface BeanBuilder<T extends Bean>

Type Parameters:

P - the type of the property.

Parameters:

metaProperty - the meta-property, not null

Returns:

the current value in the builder, null if not found or value is null

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

toString

public String toString()

Returns a string that summarises the builder.

Overrides:

toString in class Object

Returns:

a summary string, not null
