Class GraphQLAstMatcher

java.lang.Object

org.mockserver.matchers.GraphQLAstMatcher

public class GraphQLAstMatcher
extends Object

AST-aware GraphQL body matcher. Supports:

• SelectionSetMatchType.AST_EXACT — operation type, name, and top-level field set must match exactly
• SelectionSetMatchType.AST_SUBSET — expected fields must be a subset of actual query's top-level fields

This is a lightweight parser — it does not use graphql-java. It extracts operation type/name and top-level field names from GraphQL query strings using character-level parsing that handles strings, comments, and brace nesting.
