Method Summary

Modifier and Type	Method	Description
static <S, T> GeneratorBridge<S,T>	createOneToMany(Generator<T> generator, CheckedFunction<S,Stream<T>,?> bridge)	Creates a bridge that maps ONE-TO-MANY from source to destination (i.e. one or more calls to the generator for each source item)
static <S, T> GeneratorBridge<S,T>	createOneToOne(Generator<T> generator, CheckedFunction<S,T,?> bridge)	Creates a bridge that maps ONE-TO-ONE from source to destination (i.e. one call to the generator for each source item)
void	write(S element, OutputNameStyle outputNameStyle, ElementOutputter outputter)	Writes a non-indexable output (an output that isn't part of a collection of other similar items).
void	writeWithIndex(S element, String index, IndexableOutputNameStyle outputNameStyle, ElementOutputter outputter)	Writes an indexable output (many outputs of the same type, uniquely identified by an index).

Method Details

createOneToOne

public static <S,
T> GeneratorBridge<S,T> createOneToOne(Generator<T> generator,
 CheckedFunction<S,T,?> bridge)

Creates a bridge that maps ONE-TO-ONE from source to destination (i.e. one call to the generator for each source item)

Type Parameters:

S - source-type

T - destination-type

Parameters:

generator - the generator that accepts the destination type

bridge - maps a source-item to one destination-item

Returns:

a generator that accepts source-types as iterators, but actually calls a generator that uses destination types

createOneToMany

public static <S,
T> GeneratorBridge<S,T> createOneToMany(Generator<T> generator,
 CheckedFunction<S,Stream<T>,?> bridge)

Creates a bridge that maps ONE-TO-MANY from source to destination (i.e. one or more calls to the generator for each source item)

Type Parameters:

S - source-type

T - destination-type

Parameters:

generator - the generator that accepts the destination type

bridge - maps a source-item to one or more destination-items

Returns:

a generator that accepts source-types as iterators, but actually calls a generator that uses destination types

write

public void write(S element,
 OutputNameStyle outputNameStyle,
 ElementOutputter outputter)
           throws OutputWriteFailedException

Description copied from interface: ElementWriter

Writes a non-indexable output (an output that isn't part of a collection of other similar items).

Specified by:

write in interface ElementWriter<S>

Parameters:

element - the element to write.

outputNameStyle - how to write output-names.

outputter - how the element is outputted.

Throws:

OutputWriteFailedException - if the write operation fails.

writeWithIndex

public void writeWithIndex(S element,
 String index,
 IndexableOutputNameStyle outputNameStyle,
 ElementOutputter outputter)
                    throws OutputWriteFailedException

Description copied from interface: ElementWriter

Writes an indexable output (many outputs of the same type, uniquely identified by an index).

Specified by:

writeWithIndex in interface ElementWriter<S>

Parameters:

element - the element to write.

index - a string that uniquely identifies this element compared to others in the same write operation.

outputNameStyle - how to write output-names.

outputter - how the element is outputted.

Throws:

OutputWriteFailedException - if the write operation fails.
