Class FloatElementHandlerBase
java.lang.Object
org.biojava.utils.stax.StAXContentHandlerBase
org.biojava.utils.stax.FloatElementHandlerBase
- All Implemented Interfaces:
- StAXContentHandler
- public abstract class FloatElementHandlerBase
- extends StAXContentHandlerBase
StAX handler for any element which just contains a string representation of
a float.
This class collects the string data, and when it is complete, passes it to
the (abstract) setFloatValue method. Typical use of this class is as
a base for a small (often anonymous) class which takes the float value
and stores it in some variable.
