Templates

template checkError(r: var JsonReader) {..}
Source   Edit   
template customIntValueIt(r: var JsonReader; body: untyped) {..}

Convenience wrapper around customIntHandler() for parsing integers.

The body argument represents a virtual function body. So the current digit processing can be exited with return.

Source   Edit   
template customNumberValueIt(r: var JsonReader; body: untyped) {..}

Convenience wrapper around customIntHandler() for parsing numbers.

The body argument represents a virtual function body. So the current digit processing can be exited with return.

Source   Edit   
template customStringValueIt(r: var JsonReader; body: untyped) {..}

Convenience wrapper around customStringHandler() for parsing a text terminating with a double quote character '"'.

The body argument represents a virtual function body. So the current character processing can be exited with return.
