parseString

public Object parseString(String string)

Description copied from interface: Adapter

Parse a JSON string to a value. May throw exceptions when the given string is not valid JSON. The exact exceptions thrown will depend on the concrete implementation.

Converts the argument to a List. When the argument represents an array the list will contain the elements of the array, when the argument represents an object the result is a list of the object's values and for all other types the result is an empty list.

toString

public String toString(Object str)

Description copied from interface: Adapter

Converts the argument to a String. When the argument represents a string its string value is returned, otherwise a string with the value encoded as JSON is returned.

toNumber

public Number toNumber(Object n)

Description copied from interface: Adapter

Converts the argument to a Number, or null if the argument does not represent a number.

typeOf

public JmesPathType typeOf(Object value)

Description copied from interface: Adapter

Returns the JSON type of the argument. As per the JMESPath specification the types are: number, string, boolean, array, object, null.
