Method Detail

toCanonical

public String toCanonical()

Specified by:

toCanonical in class ResolvedType

buildCanonicalName

protected abstract String buildCanonicalName()

getGenericSignature

public abstract StringBuilder getGenericSignature(StringBuilder sb)

Specified by:

getGenericSignature in class JavaType

Parameters:

sb - StringBuilder to append signature to

Returns:

StringBuilder that was passed in; returned to allow call chaining

getErasedSignature

public abstract StringBuilder getErasedSignature(StringBuilder sb)

Description copied from class: JavaType

Method for accessing signature without generic type information, in form compatible with all versions of JVM, and specifically used for type descriptions when generating byte code.

Specified by:

getErasedSignature in class JavaType

Parameters:

sb - StringBuilder to append signature to

Returns:

StringBuilder that was passed in; returned to allow call chaining

getValueHandler

public <T> T getValueHandler()

Description copied from class: JavaType

Method for accessing value handler associated with this type, if any

Overrides:

getValueHandler in class JavaType

getTypeHandler

public <T> T getTypeHandler()

Description copied from class: JavaType

Method for accessing type handler associated with this type, if any

Overrides:

getTypeHandler in class JavaType

serializeWithType

public void serializeWithType(JsonGenerator jgen,
                     SerializerProvider provider,
                     TypeSerializer typeSer)
                       throws IOException,
                              JsonProcessingException

Description copied from interface: JsonSerializable

Serialization method called when additional type information is expected to be included in serialization, for deserialization to use.

Usually implementation consists of a call to one of methods in TypeSerializer (such as TypeSerializer.writeTypePrefixForObject(Object, JsonGenerator)) followed by serialization of contents, followed by another call to TypeSerializer (such as TypeSerializer.writeTypeSuffixForObject(Object, JsonGenerator)). Exact methods to call in TypeSerializer depend on shape of JSON Object used (Array, Object or scalar like String/Number/Boolean).

Note that some types (most notably, "natural" types: String, Integer, Double and Boolean) never include type information.

Specified by:

serializeWithType in interface JsonSerializable

Throws:

IOException

JsonProcessingException

serialize

public void serialize(JsonGenerator jgen,
             SerializerProvider provider)
               throws IOException,
                      JsonProcessingException

Description copied from interface: JsonSerializable

Serialization method called when no additional type information is to be included in serialization.

Specified by:

serialize in interface JsonSerializable

Throws:

IOException

JsonProcessingException

_classSignature

protected static StringBuilder _classSignature(Class<?> cls,
                            StringBuilder sb,
                            boolean trailingSemicolon)

Parameters:

trailingSemicolon - Whether to add trailing semicolon for non-primitive (reference) types or not
