MapProperty (jackson-databind 2.3.5)

java.lang.Object
- com.fasterxml.jackson.databind.ser.PropertyWriter
- - com.fasterxml.jackson.databind.ser.std.MapProperty

```
public class MapProperty
extends PropertyWriter
```
Helper class needed to support flexible filtering of Map properties with generic JSON Filter functionality. Since Maps are not handled as a collection of properties by Jackson (unlike POJOs), bit more wrapping is required.

Method Summary

Methods
Modifier and Type	Method and Description
`void`	`depositSchemaProperty(JsonObjectFormatVisitor objectVisitor)` Traversal method used for things like JSON Schema generation, or POJO introspection.
`void`	`depositSchemaProperty(ObjectNode propertiesNode, SerializerProvider provider)` Deprecated.
`PropertyName`	`getFullName()`
`String`	`getName()`
`void`	`reset(Object key, Object value, JsonSerializer<Object> keySer, JsonSerializer<Object> valueSer)` Initialization method that needs to be called before passing property to filter.
`void`	`serializeAsElement(Object pojo, JsonGenerator jgen, SerializerProvider provider)` Serialization method called when output is to be done as an array, that is, not using property names.
`void`	`serializeAsField(Object pojo, JsonGenerator jgen, SerializerProvider provider)` The main serialization method called by filter when property is to be written normally.
`void`	`serializeAsOmittedField(Object pojo, JsonGenerator jgen, SerializerProvider provider)` Serialization method that filter needs to call in cases where property is to be filtered, but the underlying data format requires a placeholder of some kind.
`void`	`serializeAsPlaceholder(Object pojo, JsonGenerator jgen, SerializerProvider provider)` Serialization method called when doing tabular (positional) output from databind, but then value is to be omitted.

    Description copied from class: PropertyWriter
    
    The main serialization method called by filter when property is to be written normally.

                             throws Exception
```
    Description copied from class: PropertyWriter
    
    Serialization method that filter needs to call in cases where property is to be filtered, but the underlying data format requires a placeholder of some kind. This is usually the case for tabular (positional) data formats such as CSV.
    
    Specified by:

    Throws:
    
    Exception
  - serializeAsElement
```
public void serializeAsElement(Object pojo,
                      JsonGenerator jgen,
                      SerializerProvider provider)
                        throws Exception
```
    Description copied from class: PropertyWriter
    
    Serialization method called when output is to be done as an array, that is, not using property names. This is needed when serializing container (Collection, array) types, or POJOs using tabular ("as array") output format.
    Note that this mode of operation is independent of underlying data format; so it is typically NOT called for fully tabular formats such as CSV, where logical output is still as form of POJOs.
    
    Specified by:

    Throws:
    
    Exception
  - serializeAsPlaceholder

public void serializeAsPlaceholder(Object pojo,
                          JsonGenerator jgen,
                          SerializerProvider provider)
                            throws Exception
```
    Description copied from class: PropertyWriter
    
    Serialization method called when doing tabular (positional) output from databind, but then value is to be omitted. This requires output of a placeholder value of some sort; often similar to PropertyWriter.serializeAsOmittedField(java.lang.Object, com.fasterxml.jackson.core.JsonGenerator, com.fasterxml.jackson.databind.SerializerProvider).
