Class JSONValueType

java.lang.Object

com.github.nedelis.jc4j.jsonvalue.JSONValueType

public final class JSONValueType
extends Object

This class allows you to convert any value from a json to a java value; You also can register your own java value types by using register(String, IJSONValueType)

All registered types will be stored in the TYPES; If you need to get definite IJSONValueType you can use saved constants of them

Modifier and Type	Method	Description
static <T> IJSONValueType<T>	register(String name, IJSONValueType<T> type)	Registers a new IJSONValueType (puts it in TYPES and returns it)

static <T> T	toJavaValue(Object jsonValue, T def)	This method tries to find correct JSONValueType for "T def" and converts given value to java value; If it can't find correct JSONValueType for "T def", then it'll issue a warning and return given default value

Method Details

register

public static <T> IJSONValueType<T> register(String name,
 IJSONValueType<T> type)

Registers a new IJSONValueType (puts it in TYPES and returns it)

Type Parameters:

T - specifies the type of returned IJSONValueType

Parameters:

name - name that will be associated with new IJSONValueType

type - IJSONValueType that will be registered

Returns:

provided IJSONValueType

toJavaValue

public static <T> T toJavaValue(Object jsonValue,
 T def)

This method tries to find correct JSONValueType for "T def" and converts given value to java value; If it can't find correct JSONValueType for "T def", then it'll issue a warning and return given default value

Type Parameters:

T - specifies which type the java value will be

Parameters:

jsonValue - value to convert

def - default value that will be returned if conversion failed; specifies the "T"

Returns:

converted json value
