init
public void init(org.w3c.dom.Element element)
throws org.xml.sax.SAXException
- Description copied from class:
Field
- If you extend this class and override this method,
do make sure to call the super.init() at some point.
- Overrides:
init
in class Field
processProperties
protected void processProperties()
throws org.xml.sax.SAXException
- Overrides:
processProperties
in class Field
getJavaType
public java.lang.Class getJavaType()
- Description copied from interface:
FieldDescriptor
- The kind of java object that can live
in this record field.
- Overrides:
getJavaType
in class Field
normalize
public java.lang.String normalize(java.lang.String s)
- Description copied from interface:
FieldDescriptor
- "normalize" the string passed in. For example,
with a case-insensitive string field, this method
would return the lower case version of the string
(or upper case if that is the "normal" form.)
- Overrides:
normalize
in class Field
- Following copied from interface:
com.revusky.oreo.FieldDescriptor
- Returns:
- the "normalized" string
getObjectFromString
public java.lang.Object getObjectFromString(Record rec,
java.lang.String s)
throws java.io.IOException
- Description copied from interface:
FieldDescriptor
- Given the string representation of a field,
return its internal java object representation.
Used in deserializing from a flat file.
checkValidValue
public void checkValidValue(Record rec,
java.lang.Object value)
throws java.io.IOException
- Note that the min-max interval is [min, max)
following python range semantics.
- Overrides:
checkValidValue
in class Field
- Following copied from interface:
com.revusky.oreo.FieldDescriptor
- Throws:
java.io.IOException
