Class PropertyValueBuffer

java.lang.Object

com.fasterxml.jackson.databind.deser.impl.PropertyValueBuffer

public class PropertyValueBuffer
extends Object

Simple container used for temporarily buffering a set of PropertyValues. Using during construction of beans (and Maps) that use Creators, and hence need buffering before instance (that will have properties to assign values to) is constructed.

Method Summary

Modifier and Type	Method	Description
boolean	assignParameter(SettableBeanProperty prop, Object value)	Method called to buffer value for given property, as well as check whether we now have values for all (creator) properties that we expect to get values for.
void	bufferAnyProperty(SettableAnyProperty prop, String propName, Object value)
void	bufferMapProperty(Object key, Object value)
void	bufferProperty(SettableBeanProperty prop, Object value)
Object	getParameter(SettableBeanProperty prop)	A variation of getParameters(SettableBeanProperty[]) that accepts a single property.
Object[]	getParameters(SettableBeanProperty[] props)	Method called to do necessary post-processing such as injection of values and verification of values for required properties, after either assignParameter(SettableBeanProperty, Object) returns true (to indicate all creator properties are found), or when then whole JSON Object has been processed,
Object	handleIdValue(DeserializationContext ctxt, Object bean)	Helper method called to handle Object Id value collected earlier, if any
boolean	hasParameter(SettableBeanProperty prop)	Returns true if the given property was seen in the JSON source by this buffer.
boolean	isComplete()
boolean	readIdProperty(String propName)	Helper method called to see if given non-creator property is the "id property"; and if so, handle appropriately.

Constructor Detail

PropertyValueBuffer

public PropertyValueBuffer(JsonParser p,
                           DeserializationContext ctxt,
                           int paramCount,
                           ObjectIdReader oir)

Method Detail

hasParameter

public final boolean hasParameter(SettableBeanProperty prop)

Returns true if the given property was seen in the JSON source by this buffer.

Since:

2.8

getParameter

public Object getParameter(SettableBeanProperty prop)
                    throws JsonMappingException

A variation of getParameters(SettableBeanProperty[]) that accepts a single property. Whereas the plural form eagerly fetches and validates all properties, this method may be used (along with hasParameter(SettableBeanProperty)) to let applications only fetch the properties defined in the JSON source itself, and to have some other customized behavior for missing properties.

Throws:

JsonMappingException

Since:

2.8

getParameters

public Object[] getParameters(SettableBeanProperty[] props)
                       throws JsonMappingException

Method called to do necessary post-processing such as injection of values and verification of values for required properties, after either assignParameter(SettableBeanProperty, Object) returns true (to indicate all creator properties are found), or when then whole JSON Object has been processed,

Throws:

JsonMappingException

readIdProperty

public boolean readIdProperty(String propName)
                       throws IOException

Helper method called to see if given non-creator property is the "id property"; and if so, handle appropriately.

Throws:

IOException

Since:

2.1

handleIdValue

public Object handleIdValue(DeserializationContext ctxt,
                            Object bean)
                     throws IOException

Helper method called to handle Object Id value collected earlier, if any

Throws:

IOException

isComplete

public boolean isComplete()

assignParameter

public boolean assignParameter(SettableBeanProperty prop,
                               Object value)

Method called to buffer value for given property, as well as check whether we now have values for all (creator) properties that we expect to get values for.

Returns:

True if we have received all creator parameters

Since:

2.6

bufferProperty

public void bufferProperty(SettableBeanProperty prop,
                           Object value)

bufferAnyProperty

public void bufferAnyProperty(SettableAnyProperty prop,
                              String propName,
                              Object value)

bufferMapProperty

public void bufferMapProperty(Object key,
                              Object value)
