  • All Implemented Interfaces:
    DataFormat<SpinJsonNode>
    public class JacksonJsonDataFormat
extends java.lang.Object
implements DataFormat<SpinJsonNode>
    Spin data format that can wrap Json content and uses Jackson as its implementation. Caches an instance of ObjectMapper according to the advice given in the Jackson documentation.

        Constructs a JavaType object based on the parameter, which has to follow Jackson's canonical type string format.
        Parameters:
        canonicalString - canonical string representation of the type
        Returns:
        the constructed java type
        Throws:
        SpinJsonDataFormatException - if no type can be constructed from the given parameter
