◆ accumulatorIn()

const QQmlJSRegisterContent & QQmlJSCompilePass::State::accumulatorIn ( ) const
inline

The accumulatorIn is the input register of the current instruction.

It holds a content, a type that content is acctually stored in, and an enclosing type of the stored type called the scope. Note that passes after the original type propagation may change the type of this register to a different type that the original one can be coerced to. Therefore, when analyzing the same instruction in a later pass, the type may differ from what was seen or requested ealier. See \l {readAccumulator()}. The input type may then need to be converted to the expected type.
