Interface ImmutableMap

All Known Implementing Classes:
ImmutableMapImpl
public interface ImmutableMap
An immutable map. (eg unmodifiable storage of parameter name-value pairs). The values may be primitive values or List, Set, Map of values. All internal containers are unmodifiable too. Internal class only, not in the public API.

  • Method Details

    • hasValue

      boolean hasValue​(String parameterName)
      Parameters:
      parameterName - to be checked parameter name
      Returns:
      true if there is defined some value for the parameter. null can be a value too

    • getValue

      Object getValue​(String parameterName)
      Parameters:
      parameterName - the name of the parameter
      Returns:
      a value of the parameter under the name `parameterNamer

    • putValue

      ImmutableMap putValue​(String parameterName, Object value)
      Parameters:
      parameterName - to be set parameter name
      value - the new value
      Returns:
      copies this ImmutableMap, sets the new value there and returns that copy

    • asMap

      Map<String,​Object> asMap()
      Returns:
      underlying unmodifiable Map<String, Object>

    • checkpoint

      ImmutableMap checkpoint()
      Returns:
      a new instance of ImmutableMap, which inherits all values from this ImmutableMap Any call of putValue(String, Object) is remembered in local Map of parameters. At the end of process the getModifiedValues() can be used to return all the parameters which were changed after local ImmutableMap was created

    • getModifiedValues

      Map<String,​Object> getModifiedValues()
      Returns:
      the modified parameters since last call to checkpoint()
