Method Detail

findMetaBean

public MetaBean findMetaBean(java.lang.Class<?> beanType)

Description copied from interface: SerDeserializer

Lookup the meta-bean for the speecified type.

If the type is not a bean, then null may be returned.

Specified by:

findMetaBean in interface SerDeserializer

Parameters:

beanType - the type being processed, not null

Returns:

the meta-bean, null if not a bean type

createBuilder

public BeanBuilder<?> createBuilder(java.lang.Class<?> beanType,
                                    MetaBean metaBean)

Description copied from interface: SerDeserializer

Creates the stateful builder that captures state as the parse progresses.

This is normally a BeanBuilder however any type may be returned.

Specified by:

createBuilder in interface SerDeserializer

Parameters:

beanType - the type being processed, not null

metaBean - the meta-bean, null if not a bean type

Returns:

the builder, null if not interested in the parse progress

findMetaProperty

public MetaProperty<?> findMetaProperty(java.lang.Class<?> beanType,
                                        MetaBean metaBean,
                                        java.lang.String propertyName)

Description copied from interface: SerDeserializer

Lookup the meta-property for the specified property name.

Return null if a property has been deleted, which will cause the parser to discard the property.

Return a non-null meta-property to parse the property. If the property was renamed, or had a type change, then the meta-property should match the property as originally stored.

Specified by:

findMetaProperty in interface SerDeserializer

Parameters:

beanType - the type being processed, not null

metaBean - the meta-bean, null if not a bean type

propertyName - the property name being parsed, not null

Returns:

the meta-property, null to ignore the property

setValue

public void setValue(BeanBuilder<?> builder,
                     MetaProperty<?> metaProp,
                     java.lang.Object value)

Description copied from interface: SerDeserializer

Sets the parsed value into the builder.

Specified by:

setValue in interface SerDeserializer

Parameters:

builder - the builder, null if not interested in the parse progress

metaProp - the meta-property, not null

value - the parsed value, may be null

build

public java.lang.Object build(java.lang.Class<?> beanType,
                              BeanBuilder<?> builder)

Description copied from interface: SerDeserializer

Builds the resulting object.

This method finishes the builder and returns the final object. The migrator could validate or manipulate data here once all data is parsed, for example to default a missing field.

Specified by:

build in interface SerDeserializer

Parameters:

beanType - the type being processed, not null

builder - the builder, null if not interested in the parse progress

Returns:

the final built object, may be null

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
