Method Summary

Modifier and TypeMethod and Description
protected void
_writeValue(Blob value, JsonGenerator gen, SerializationContext ctxt)

public void
acceptJsonFormatVisitor(JsonFormatVisitorWrapper visitor, JavaType typeHint)

Overrides tools.jackson.databind.ser.std.StdScalarSerializer.acceptJsonFormatVisitor.

Implements tools.jackson.databind.jsonFormatVisitors.JsonFormatVisitable.acceptJsonFormatVisitor.

Default implementation specifies no format.

public boolean
isEmpty(SerializationContext provider, Blob value)

Overrides tools.jackson.databind.ValueSerializer.isEmpty.

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

public void
serialize(Blob value, JsonGenerator gen, SerializationContext ctxt)

Implements abstract tools.jackson.databind.ser.std.StdSerializer.serialize.

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

public void
serializeWithType(Blob value, JsonGenerator gen, SerializationContext ctxt, TypeSerializer typeSer)

Overrides tools.jackson.databind.ser.std.StdScalarSerializer.serializeWithType.

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.

public void acceptJsonFormatVisitor(JsonFormatVisitorWrapper visitor, JavaType typeHint)

Overrides tools.jackson.databind.ser.std.StdScalarSerializer.acceptJsonFormatVisitor.

Implements tools.jackson.databind.jsonFormatVisitors.JsonFormatVisitable.acceptJsonFormatVisitor.

Doc from tools.jackson.databind.ser.std.StdSerializer.acceptJsonFormatVisitor.

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

public boolean isEmpty(SerializationContext provider, Blob value)

Overrides tools.jackson.databind.ValueSerializer.isEmpty.

Doc from tools.jackson.databind.ValueSerializer.isEmpty.

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 tools.jackson.databind.ser.std.StdScalarSerializer.serializeWithType.

Doc from tools.jackson.databind.ser.std.StdScalarSerializer.serializeWithType.

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.
