Class JSONFileType

java.lang.Object
  org.mule.common.metadata.parser.json.AbstractType
      org.mule.common.metadata.parser.json.JSONFileType

All Implemented Interfaces:

JSONType

public class JSONFileType
extends AbstractType

Lazy type loading for JSON schema files. Objects of this class correspond to files on the filesystem, each given by a File, which contain JSON Schema expressions. However, the JSON schema expression is only loaded and parsed the first time that either contains or explain is called on this object: lazy loading. This is so that we can support resolution of mutually-recursive types, from files in a single directory.
