Variable_definition(VarName, VarType, VarDefault, VarDirs) VariableDefinitions is a list of terms of the form Name is either the atom null or a string denoting the Obtained from parsing Source as a GraphQL executable document.ĭocument is a list of terms representing GraphQL executableĭefinitions, each being one of: operation (Type, Name, VariableDefinitions, Directives, SelectionSet) Type is one of the atoms query, mutation or subscription. graphql_read_document (+Source, -Document, +Options) is semidet True when Document is a term representing the abstract syntax tree Same format as used by graphql_read_document/3. Result is a term representing the given GraphQL document in the Variable_names(+VarNames) in graphql_read_document/3. Of a variable that is an element of Args. The special lexical construct "" where VarName is the name Prolog variables can be incorporated in the quasi-quotation using graphql (+Content, +Args, -VariableNames, -Result) is det Quasi-quotation syntax for embedding GraphQL in Prolog text.
