Method Detail

create

public SerIterator create(Object value,
                          MetaProperty<?> prop,
                          Class<?> beanClass)

Creates an iterator wrapper for a meta-property value.

Parameters:

value - the possible collection-like object, not null

prop - the meta-property defining the value, not null

beanClass - the class of the bean, not the meta-property, for better generics, not null

Returns:

the iterator, null if not a collection-like type

createChild

public SerIterator createChild(Object value,
                               SerIterator parent)

Creates an iterator wrapper for a value retrieved from a parent iterator.

Allows the parent iterator to define the child iterator using generic type information. This handles cases such as a List as the value in a Map.

Parameters:

value - the possible collection-like object, not null

parent - the parent iterator, not null

Returns:

the iterator, null if not a collection-like type

defaultToObjectClass

protected Class<?> defaultToObjectClass(Class<?> type)

Defaults input class to Object class.

Parameters:

type - the type, may be null

Returns:

the type, not null

createIterable

public SerIterable createIterable(String metaTypeDescription,
                                  JodaBeanSer settings,

Creates an iterator wrapper for a meta-type description.

Parameters:

metaTypeDescription - the description of the collection type, not null

settings - the settings object, not null

knownTypes - the known types map, null if not using known type shortening

Returns:

the iterable, null if not a collection-like type

createIterable

public SerIterable createIterable(SerIterable iterable)

Creates an iterator wrapper for a child where there are second level generic parameters.

Parameters:

iterable - the parent iterable, not null

Returns:

the iterable, null if not a collection-like type

createIterable

public SerIterable createIterable(MetaProperty<?> prop,
                                  Class<?> beanClass)

Creates an iterator wrapper for a meta-property value.

Parameters:

prop - the meta-property defining the value, not null

beanClass - the class of the bean, not the meta-property, for better generics, not null

Returns:

the iterable, null if not a collection-like type
