public abstract class ChildrenMatch
extends org.eclipse.viatra.query.runtime.api.impl.BasePatternMatch
ChildrenMatcher
.
Class fields correspond to parameters of the pattern. Fields with value null are considered unassigned. Each instance is a (possibly partial) substitution of pattern parameters, usable to represent a match of the pattern in the result of a query, or to specify the bound (fixed) input parameters when issuing a query.

The returned match will be immutable. Use newEmptyMatch()
to obtain a mutable match object.
pParent
- the fixed value of pattern parameter parent, or null if not bound.pChild
- the fixed value of pattern parameter child, or null if not bound.
