public interface StepCondition
extends SyntaxTree

Interface for the condition which corresponds to a node in the syntax tree.

A condition is represented by a predicate predicate() and a getMetadata() describing the node.

Modifier and Type	Method and Description
default StepCondition	and(StepCondition condition) Returns a condition checking if the node predicate and the given condition predicate evaluate to true.
Metadata	getMetadata() Returns the metadata to describe this node.
default StepCondition	not() Returns a condition checking if the node predicate does not evaluate to true.
default StepCondition	or(StepCondition condition) Returns a condition checking if the node predicate or the given condition predicate evaluate to true.
