Method Detail

accept

public <Input,Output> Output accept(JmesPathVisitor<Input,Output> visitor,
                                    Input input)
                             throws InvalidTypeException

Delegates to either the CodeGen visitor(Comparator) or Evaluation visitor(Comparator) based on the type of JmesPath visitor

Type Parameters:

Input - Input type for the visitor CodeGen visitor: Void Evaluation visitor: JsonNode

Output - Output type for the visitor CodeGen visitor: String Evaluation visitor: JsonNode

Parameters:

visitor - CodeGen visitor or Evaluation visitor

input - Input expression that needs to be evaluated

Returns:

Corresponding output is returned. Evaluated String in the case of CodeGen visitor or an evaluated JsonNode in the case of Evaluation visitor

Throws:

InvalidTypeException

matches

public boolean matches(com.fasterxml.jackson.databind.JsonNode lhs,
                       com.fasterxml.jackson.databind.JsonNode rhs)

Checks whether lhs is equal to rhs

Specified by:

matches in class Comparator

Parameters:

lhs - Lhs expression

rhs - Rhs expression

Returns:

True if lhs is equal to rhs; False otherwise
