Class SmallAnnotation
java.lang.Object
org.biojava.utils.AbstractChangeable
org.biojava.bio.AbstractAnnotation
org.biojava.bio.SmallAnnotation
- All Implemented Interfaces:
- Annotation, Changeable, java.io.Serializable
- 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
- Author:
- Thomas Down, Matthew Pocock
- See Also:
- Serialized Form
- For general use:
- A minimal-memory alternative to SimpleAnnotation
- For advanced users:
- 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.
