wrench::DagOfTasks
-
class wrench::DagOfTasks
An internal class that uses the Boost Graph Library to implement a DAG of WorkflowTask objects.
Public Functions
-
void addEdge(WorkflowTask *src, WorkflowTask *dst)
Method to add an edge between to task vertices.
- Parameters
src – the source task
dst – the destination task
-
void addVertex(const WorkflowTask *task)
Method to add a task vertex to the DAG.
- Parameters
task – the task
-
bool doesEdgeExist(const WorkflowTask *src, const WorkflowTask *dst)
Method to check whether an edge exists between to task vertices.
- Parameters
src – the source task
dst – the destination task
- Returns
true if there is a path between the tasks
-
bool doesPathExist(const WorkflowTask *src, const WorkflowTask *dst)
Method to check whether a path exists between to task vertices.
- Parameters
