getInstance() : \JmesPath\FnDispatcher
Gets a cached instance of the default function implementations.
Dispatches to named JMESPath functions using a single function that has the following signature:
mixed $result = fn(string $function_name, array $args)
validateSeq(string $from, array $types, mixed $a, mixed $b) : mixed
Validates value A and B, ensures they both are correctly typed, and of the same type.
| string | $from | String of function:argument_position |
| array | $types | Array of valid value types. |
| mixed | $a | Value A |
| mixed | $b | Value B |
reduce(string $from, array $values, array $types, callable $reduce) : mixed
Reduces and validates an array of values to a single value using a fn.
| string | $from | String of function:argument_position |
| array | $values | Values to reduce. |
| array | $types | Array of valid value types. |
| callable | $reduce | Reduce function that accepts ($carry, $item). |
wrapExpression(string $from, callable $expr, array $types) : callable
Validates the return values of expressions as they are applied.
| string | $from | Function name : position |
| callable | $expr | Expression function to validate. |
| array | $types | Array of acceptable return type values. |
Returns a wrapped function
