All Implemented Interfaces:

EclipseLinkExpressionVisitor, ExpressionVisitor

public class EclipseLinkParameterTypeVisitor
extends AbstractEclipseLinkParameterTypeVisitor

This visitor calculates the type of an input parameter.

Provisional API: This interface is part of an interim API that is still under development and expected to change significantly before reaching stability. It is available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.

2.4

Version:

2.5
