Detailed Description

Composite predicate that forms a logical OR (disjunction) from its child predicates.

A node passes the check if at least one child predicate returns true. Evaluation short-circuits on the first true result.

auto pred = NodePredicateOr::New(
  NodePredicateDataType::New("Image"),
  NodePredicateDataType::New("Surface"));
auto imagesOrSurfaces = dataStorage->GetSubset(pred);

Member Function Documentation

CheckNode()

bool mitk::NodePredicateOr::CheckNode ( const DataNode *  node ) const

overridevirtual

Check whether the node satisfies any child predicate (logical OR).

Parameters

[in]

node

The DataNode to evaluate. Must not be nullptr.

Returns

true if at least one child predicate returns true for the node.

Exceptions

std::invalid_argument

if no child predicates have been added or node is nullptr.
