Constructor Detail

PojoSerializer

public PojoSerializer()

Create a new serializer for PojoType type.

Method Detail

initialize

public PojoType initialize(java.lang.Class<? extends PojoType> definitionType)
                    throws java.lang.ReflectiveOperationException

Create an initial (default) instance for this serializer.

Specified by:

initialize in class JavaTypeSerializer<PojoType>

Parameters:

definitionType - The type as it appears at the parameter's definition.

Returns:

A new instance of the parameter's type.

Throws:

java.lang.InstantiationException

java.lang.IllegalAccessException

java.lang.ReflectiveOperationException

fromJson

public PojoType fromJson(PojoType arg,
                         java.lang.String sval)
                  throws RequestArgumentError

Parse the string JSON representation and assign it to the given argument. If null or not mutable, a new instance will be created.

Specified by:

fromJson in class JavaTypeSerializer<PojoType>

Parameters:

arg - The argument (obtained via initialize(java.lang.Class<? extends com.goldencode.p2j.rest.serializers.PojoType>).

sval - The string JSON representation of this argument.

Returns:

The argument instance.

Throws:

RequestArgumentError - If the argument can't be parsed.

toJson

public com.fasterxml.jackson.databind.JsonNode toJson(PojoType val)

Serialize the given instance to JSON.

Specified by:

toJson in class JavaTypeSerializer<PojoType>

Parameters:

val - The instance to serialize.

Returns:

The JSON representation of this instance.

getProperties

private java.util.Map<java.lang.String,java.lang.reflect.Method[]> getProperties(java.lang.Class<? extends PojoType> clazz)

Resolve the POJO serializable properties for the given type. These properties include only non-transient fields defined directly defined in the specified type, for which a getter and a setter method exists, following the Java bean convention.

Parameters:

clazz - The POJO type.

Returns:

The mapping of Java fields to their getter (index 0) and setter (index 1) methods.
