Detailed Description

template<typename... Funcs>
struct inviwo::LambdaNetworkVisitor< Funcs >

A Helper class to construct a NetworkVisitor from a set of lambda functions.

A number of different overloads can be given. Processors will be visited before children in order of priority:

• [](Processor&, NetworkVisitorEnter) -> bool
• [](Processor&, NetworkVisitorEnter)
• [](Processor&) -> bool
• [](Processor&)

Processors will be visited after children:

• [](Processor&, NetworkVisitorExit)

CompositeProperties will be visited before children in order of priority:

• [](CompositeProperty&, NetworkVisitorEnter) -> bool
• [](CompositeProperty&, NetworkVisitorEnter)
• [](CompositeProperty&) -> bool
• [](CompositeProperty&)
• [](Property&) -> bool
• [](Property&)

CompositeProperties will be visited after children:

• [](CompositeProperty&, NetworkVisitorExit) -> void

Properties will be visited by:

• [](Property&)

LambdaNetworkVisitor visitor{[](Property& property) {
                                 // Do something for all properties
                                 return true; // visit all children
                             },
                             [](Processor&, NetworkVisitorEnter) {
                                 // Do something for a processor before properties
                                 return true; // Visit children
                             },
                             [](Processor&, NetworkVisitorExit) {
                                 // Do something for a processor after properties
                             }};
