Flow conditions

BPMN flow conditions are expressions used to determine the path of execution in a BPMN process based on specific criteria. They enable dynamic routing of process instances by evaluating the conditions at runtime and choosing the appropriate sequence flow.

Setting conditionals

Setting conditions with regex involves using regular expressions to define a pattern that a particular piece of data must match. When the data matches the specified regex pattern, the condition is met, allowing for actions or decisions to be taken based on that match.
