Class PropertyValueBuffer

java.lang.Object

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

public final 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.

Constructor Detail

PropertyValueBuffer

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

Method Detail

inject

public void inject(SettableBeanProperty[] injectableProperties)

getParameters

protected final Object[] getParameters(Object[] defaults)

Parameters:

defaults - If any of parameters requires nulls to be replaced with a non-null object (usually primitive types), this is a non-null array that has such replacement values (and nulls for cases where nulls are ok)

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

buffered

protected PropertyValue buffered()

isComplete

public boolean isComplete()

assignParameter

public boolean assignParameter(int index,
                               Object value)

Returns:

True if we have received all creator parameters

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)
