JsonObject.ReadFrom(InStream) Method

  • מאמר

Version: Available or changed with runtime version 1.0.

Reads the JSON data from the stream into a JsonObject variable.

Syntax

[Ok := ]  JsonObject.ReadFrom(InStream: InStream)

Parameters

JsonObject
 Type: JsonObject
An instance of the JsonObject data type.

InStream
 Type: InStream
The InStream object from which the JSON data will be read.

Return Value

[Optional] Ok
 Type: Boolean
true if the read was successful; otherwise, false. If you omit this optional return value and the operation does not execute successfully, a runtime error will occur.

Remarks

This method can fail if the stream is in an invalid state or if the JSON data is malformed. If the operation succeeds, the JsonObject will be disconnected from its current JSON tree and the data contained by the JsonObject will be replaced with the new value. To delete the contents in a JsonObject variable use the Clear function.

Clear(JsonObject)
