read()

Expected< bool > Reader::read

(

Object &

Obj

)

Read one object from the input buffer, advancing past it.

The Obj is updated with the kind of the object read, and the corresponding union member is updated.

For the collection objects (Array and Map), only the length is read, and the caller must make and additional N calls (in the case of Array) or N*2 calls (in the case of Map) to Read to retrieve the collection elements.

Parameters

[out]

Obj

filled with next object on success.

Returns

true when object successfully read, false when at end of input (and so Obj was not updated), otherwise an error.
