Class SmallAnnotation

  • All Implemented Interfaces:
    Serializable, Annotation
    public class SmallAnnotation
extends AbstractAnnotation
    Annotation that is optimized for memory usage. Access time is linear, so SmallAnnotations are not recommended when the number of entries is large. However, they are fine for small numbers of keys.
    Since:
    1.2 A minimal-memory alternative to SimpleAnnotation When creating a large number of small Annotation instances, it is worth instantiating SmallAnnotation. Small is anything up to at least 30 properties but will vary with the JavaVM and underlying platform.

    • Constructor Detail

      • SmallAnnotation

        public SmallAnnotation()
        Return a new SmallAnnotation optimised for small sets of properties.

      • SmallAnnotation

        public SmallAnnotation​(Annotation ann)
        Return a new SmallAnnotation that copies all values from another annoation.
        Parameters:
        ann - the Annoation to copy all values from
        Throws:
        NullPointerException - if ann is null

      • SmallAnnotation

        public SmallAnnotation​(Map map)
        Return a new SmallAnnotation that copies all values from a Map.
        Parameters:
        map - the Map to copy values from

    • Method Detail

      • getProperties

        protected final Map getProperties()
        Description copied from class: AbstractAnnotation
        Implement this to return the Map delegate. Modifying this return value will modify the properties associated with this annotation. From code in the 1.2 version of AbstractAnnotation This is required for the implementation of an Annotation that extends AbstractAnnotation. Where possible implementations should be backed with a LinkedHashMap or similar so properties are iterated in the order they were added.
        Specified by:
        getProperties in class AbstractAnnotation
        Returns:
        a Map containing all properties

      • propertiesAllocated

        protected final boolean propertiesAllocated()
        Description copied from class: AbstractAnnotation
        A convenience method to see if we have allocated the properties Map. This is required for the implementation of an Annotation that extends AbstractAnnotation.
        Specified by:
        propertiesAllocated in class AbstractAnnotation
        Returns:
        true if the properties have been allocated, false otherwise
