All Implemented Interfaces:

JsonFormatVisitable

public class JavaSqlBlobSerializer
extends StdScalarSerializer<Blob>

protected void	_writeValue(Blob value, tools.jackson.core.JsonGenerator gen, SerializationContext ctxt)
void	acceptJsonFormatVisitor(JsonFormatVisitorWrapper visitor, JavaType typeHint)	Default implementation specifies no format.
boolean	isEmpty(SerializationContext provider, Blob value)	Method called to check whether given serializable value is considered "empty" value (for purposes of suppressing serialization of empty values).
void	serialize(Blob value, tools.jackson.core.JsonGenerator gen, SerializationContext ctxt)	Method that can be called to ask implementation to serialize values of type this serializer handles.
void	serializeWithType(Blob value, tools.jackson.core.JsonGenerator gen, SerializationContext ctxt, TypeSerializer typeSer)	Default implementation will write type prefix, call regular serialization method (since assumption is that value itself does not need JSON Array or Object start/end markers), and then write type suffix.

Method Details

isEmpty

public boolean isEmpty(SerializationContext provider,
 Blob value)

Description copied from class: ValueSerializer

Method called to check whether given serializable value is considered "empty" value (for purposes of suppressing serialization of empty values).

Default implementation will consider only null values to be empty.

Overrides:

isEmpty in class ValueSerializer<Blob>

serialize

public void serialize(Blob value,
 tools.jackson.core.JsonGenerator gen,
 SerializationContext ctxt)
               throws tools.jackson.core.JacksonException

Description copied from class: ValueSerializer

Method that can be called to ask implementation to serialize values of type this serializer handles.

Specified by:

serialize in class StdSerializer<Blob>

Parameters:

value - Value to serialize; can not be null.

gen - Generator used to output resulting Json content

ctxt - Context that can be used to get serializers for serializing Objects value contains, if any.

Throws:

tools.jackson.core.JacksonException

serializeWithType

public void serializeWithType(Blob value,
 tools.jackson.core.JsonGenerator gen,
 SerializationContext ctxt,
 TypeSerializer typeSer)
                       throws tools.jackson.core.JacksonException

Description copied from class: StdScalarSerializer

Default implementation will write type prefix, call regular serialization method (since assumption is that value itself does not need JSON Array or Object start/end markers), and then write type suffix. This should work for most cases; some sub-classes may want to change this behavior.

Overrides:

serializeWithType in class StdScalarSerializer<Blob>

Parameters:

value - Value to serialize; can not be null.

gen - Generator used to output resulting Json content

ctxt - Context that can be used to get serializers for serializing Objects value contains, if any.

typeSer - Type serializer to use for including type information

Throws:

tools.jackson.core.JacksonException

_writeValue

protected void _writeValue(Blob value,
 tools.jackson.core.JsonGenerator gen,
 SerializationContext ctxt)
                    throws tools.jackson.core.JacksonException

Throws:

tools.jackson.core.JacksonException

acceptJsonFormatVisitor

public void acceptJsonFormatVisitor(JsonFormatVisitorWrapper visitor,
 JavaType typeHint)

Description copied from class: StdSerializer

Default implementation specifies no format. This behavior is usually overriden by custom serializers.

Specified by:

acceptJsonFormatVisitor in interface JsonFormatVisitable

Overrides:

acceptJsonFormatVisitor in class StdScalarSerializer<Blob>

typeHint - Type of element (entity like property) being visited
