Enclosing class:
JmesPathRuntime
public static final class JmesPathRuntime.Value extends Object
An intermediate value for JMESPath expressions, encapsulating the different data types supported by JMESPath and the operations on that data.

  • Constructor Details

    • Value

      public Value(Object value)
      Create a non-projection value, where the value type is determined reflectively.

  • Method Details

    • value

      public Object value()
      Retrieve the actual value that this represents (this will be the same value passed to the constructor).

    • values

      public List<Object> values()
      Retrieve the actual value that this represents, as a list of object.

    • booleanValue

      public Boolean booleanValue()
      Retrieve the actual value that this represents, as a Boolean. Note that only null, boolean and string types are supported.

    • stringValue

      public String stringValue()
      Retrieve the actual value that this represents, as a String. Note that collection types are not supported.

    • stringValues

      public List<String> stringValues()
      Retrieve the actual value that this represents, as a list of String. Note that if the contents of the list is not String, an exception is thrown. If the value has a different type, the code makes a best effort to return a single element list of String. See stringValue.

    • stringValuesMap

      public Map<String,String> stringValuesMap()
      Retrieve the actual value that this represents, as a map of Strings. Note that if the contents of the map are not String, or if the value has a different type, an exception is thrown.

    • constant

      public JmesPathRuntime.Value constant(JmesPathRuntime.Value value)
      Convert this value to a new constant value, discarding the current value.

    • constant

      public JmesPathRuntime.Value constant(Object constant)
      Convert this value to a new constant value, discarding the current value.
