Class LoadJson

java.lang.Object

net.sourceforge.plantuml.tim.stdlib.SimpleReturnFunction

net.sourceforge.plantuml.tim.stdlib.LoadJson

All Implemented Interfaces:

TFunction

public class LoadJson
extends SimpleReturnFunction

Loads JSON data from file or URL source.

Supports three parameters for datasource, default JSON value and charset. The datasource will be checked against the security rules.

Examples:

     @ startuml
     ' loads a local file
     !$JSON_LOCAL_RELATIVE=%load_json("file.json")

     ' loads a local file from an absolute file path
     !$JSON_LOCAL_ABS=%load_json("c:/loaded/data/file.json")

     ' tries to load a local file and returns an empty JSON
     !$JSON_LOCAL_REL_EMPTY=%load_json("file-not-existing.json")

     ' tries to load a local file and returns an default JSON
     !$DEF_JSON={"status":"No data found"}
     !$JSON_LOCAL_REL_DEF=%load_json("file-not-existing.json", $DEF_JSON)

     ' loads a local file with a specific charset (default is UTF-8)
     !$JSON_LOCAL_RELATIVE_CHARSET=%load_json("file.json", "{}", "iso-8859-1")

     ' loads a remote JSON from an endpoint (and default, if not reachable)
     !$STATUS_NO_CONNECTION={"status": "No connection"}
     !$JSON_REMOTE_DEF=%load_json("https://localhost:7778/management/health", $STATUS_NO_CONNECTION)
     status -> $JSON_REMOTE_DEF.status
     @ enduml
