Class CollectionJsonSerialization<E,C extends Collection<E>>

java.lang.Object
  de.hpi.fgis.dude.util.data.json.auto.AutoJsonSerialization<C>
      de.hpi.fgis.dude.util.data.json.auto.CollectionJsonSerialization<E,C>

Type Parameters:

E - the element type

C - the collection type

 class CollectionJsonSerialization<E,C extends Collection<E>>
extends AutoJsonSerialization<C>

Collection json serialization support.

Constructor Summary

CollectionJsonSerialization(BoundType genericType)
Initializes the json serialization for the given type.

Method Summary

C	read(DuDeJsonParser<?> parser, Object currentValue) Creates an instance of the wrapped type and initializes the content with the json provided by the given DuDeJsonParser.
void	write(DuDeJsonGenerator generator, C collection) Writes the given instance to the specified DuDeJsonGenerator.
protected void	writeWithType(DuDeJsonGenerator generator, C value) Writes the given value with additional type information. This method should be used when the actual type of a value cannot be inferred from the declaration. The typical scenario is the usage of polymorphism without secondary information which would allow to infer the type.

CollectionJsonSerialization

public CollectionJsonSerialization(BoundType genericType)

Initializes the json serialization for the given type.

Parameters:

genericType - the type to wrap

Method Detail

read

public C read(DuDeJsonParser<?> parser,
              Object currentValue)
                             throws org.codehaus.jackson.JsonParseException,
                                    IOException

Description copied from class: AutoJsonSerialization

Creates an instance of the wrapped type and initializes the content with the json provided by the given DuDeJsonParser. This method might reuse the currentValue but should in most cases use the actual type information of the currentValue to create a new instance.

Specified by:

read in class AutoJsonSerialization<C extends Collection<E>>

Parameters:

parser - the parser to read from

currentValue - the current value of the field which should be populated by the result of this method or null if this is the root object

Returns:

an instance of T

Throws:

org.codehaus.jackson.JsonParseException - If an error occurred while parsing the data.

IOException - If an error occurred while reading from the stream.

write

public void write(DuDeJsonGenerator generator,
                  C collection)
           throws org.codehaus.jackson.JsonGenerationException,
                  IOException

Description copied from class: AutoJsonSerialization

Writes the given instance to the specified DuDeJsonGenerator.

Specified by:

write in class AutoJsonSerialization<C extends Collection<E>>

Parameters:

generator - the generator to write to

collection - the jsonable to write

Throws:

org.codehaus.jackson.JsonGenerationException - If an error occurs while generating the Json syntax.

IOException - If an error occurs while accessing the underlying stream.

writeWithType

protected void writeWithType(DuDeJsonGenerator generator,
                             C value)
                      throws org.codehaus.jackson.JsonGenerationException,
                             IOException

Description copied from class: AutoJsonSerialization

Writes the given value with additional type information.
This method should be used when the actual type of a value cannot be inferred from the declaration.
The typical scenario is the usage of polymorphism without secondary information which would allow to infer the type.

Overrides:

writeWithType in class AutoJsonSerialization<C extends Collection<E>>

Parameters:

generator - the DuDeJsonGenerator to write to

value - the object to write

Throws:

org.codehaus.jackson.JsonGenerationException - If an error occurs while generating the Json syntax.

IOException - If an error occurs while accessing the underlying stream.
