TGraphQLSchema Class

Non-visual component representing a GraphQL schema.

Remarks

TGraphQLSchema component provides schema information to other non-visual components, like GraphQL HTTP dispatchers, for example. It encapsulates a TSchemaDocument class. Common usage is to provide a schema document specification in the Definition property and add schema initialization code in OnInitSchema event handler. The component will internally create a TSchemaDocument instance based on the schema document definition, and then call OnInitSchema event passing the created instance.
