Class VariableAccumulator

java.lang.Object

graphql.normalized.VariableAccumulator

public class VariableAccumulator
extends Object

This accumulator class decides on whether to create a variable for a query argument and if so it tracks what variables were made. The ExecutableNormalizedOperationToAstCompiler then uses all the variables when it compiles the final document.
