All Implemented Interfaces:

java.io.Serializable

Direct Known Subclasses:

ArrayElementParamDescriptor, ArrayOfBeanPathParamDescriptor, ArrayOfBeanTyperParamDescriptor, BeanTyperParamDescriptor, IdentityParamDescriptor

public abstract class DynamicParamDescriptor
extends ParamDescriptor

This is an abstract class for ParamDescriptors that should be extended by the various ways to derive the type of a parameter dynamically. The resolver can be used to access the types + values of other parameters that this parameter may depend upon.

Sub-classes of this can be relatively generic: ArrayElementOfParamDescriptor ArrayOfParamDescriptor, or fairly specific: TargetingArrayParamDescriptor.

public DynamicParamDescriptor(java.lang.String pName,
                              java.lang.String pDescription,
                              java.lang.Class pParamClass,

                              boolean pLocal)

Construct an ArrayElementParamDescriptor. Most of these arguments are the same as those to ParamDescriptor. The last argument, pArrayParamName, is the name of the input parameter that we should base our output parameter's type on.

Method Detail

getParamInfo

public abstract ObjectTypeInfo getParamInfo(ParamDescriptorResolver pResolver)

Returns an ObjectTypeInfo that describes the type of this parameter. This method uses the pResolver argument to lookup the types of its input parameters and defines this parameter in terms of those types.
