## org.biojava.bio
Class SimpleAnnotation

    java.lang.Object
      org.biojava.utils.AbstractChangeable
          org.biojava.bio.AbstractAnnotation
              org.biojava.bio.SimpleAnnotation

All Implemented Interfaces:
  Serializable, Annotation, Changeable

    public class SimpleAnnotation

extends AbstractAnnotation

A no-frills implementation of Annotation that is just a wrapper around a `LinkedHashMap`.

It will allow you to set any property, but will throw exceptions if you try to retrieve a property that is not set. Because of the use of a `LinkedHashMap` properties are iterated in the order they are entered.

When you need to make a new Annotation instance and will want to populate it with properties, use this class.

  1.0

Constructor Detail

### SimpleAnnotation

    public SimpleAnnotation()

  Create a new, empty SimpleAnnotation instance.

### SimpleAnnotation

    public SimpleAnnotation(Annotation ann)

  Create a new SimpleAnnotation by copying the properties from another one. The new Annotation instance will be independant of the original.

  Parameters:
    `ann` - the Annotation to copy

### SimpleAnnotation

    public SimpleAnnotation(Map map)

  Create a new SimpleAnnotation using the values in a Map.

  Parameters:
    `map` - the Map to copy properties out of

Method Detail

### getProperties

    protected final Map getProperties()

  Get the property value pairs in this annotation

  Specified by:
    `getProperties` in class `AbstractAnnotation`
  Returns:
    a `LinkedHashMap` of properties and values

### propertiesAllocated

    protected final boolean propertiesAllocated()

  Test to see if any properties have been allocated

  Specified by:
    `propertiesAllocated` in class `AbstractAnnotation`
  Returns:
    true if any have (even if they have since been removed), false otherwise
