Method Detail

getParserName

public static String getParserName()

setParserName

public static void setParserName(String fqn)

fromJson

public static Bindings fromJson(String json)

Parse the JSON string as a javax.script.Bindings instance.

Parameters:

json - A Standard JSON formatted string

Returns:

A javax.script.Bindings instance

makeStructureTypes

public static String makeStructureTypes(String nameForStructure,
                                        Bindings bindings,
                                        boolean mutable)

Makes a tree of structure types reflecting the Bindings.

If the bindings represent a Json Schema format (v.4), the types are transformed according to that schema. Otherwise, the bindings are assumed to be a sample Json document whereby types are derived directly from the sample. Note when multiple samples exist for the same type eg., array elements, the samples are merged and reconciled.

A structure type contains a property member for each name/value pair in the Bindings. A property has the same name as the key and follows these rules:

• If the type of the value is a "simple" type, such as a String or Integer, the type of the property matches the simple type exactly
• Otherwise, if the value is a Bindings type, the property type is that of a child structure with the same name as the property and recursively follows these rules
• Otherwise, if the value is a List, the property is a List parameterized with the component type, and the component type recursively follows these rules

transformJsonObject

public static IJsonType transformJsonObject(String name,
                                            JsonSchemaType parent,
                                            Object jsonObj)

mergeTypes

public static IJsonType mergeTypes(IJsonType type1,
                                   IJsonType type2)
