Method Detail

init

public void init(org.w3c.dom.Element element)
          throws org.xml.sax.SAXException

Overrides:

init in class Field

org.xml.sax.SAXException

processProperties

protected void processProperties()
                          throws org.xml.sax.SAXException

Overrides:

processProperties in class Field

org.xml.sax.SAXException

getJavaType

public java.lang.Class getJavaType()

Description copied from interface: FieldDescriptor

The kind of java object that can live in this record field.

Specified by:

getJavaType in interface FieldDescriptor

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.)

Specified by:

normalize in interface FieldDescriptor

Overrides:

normalize in class Field

Returns:

the "normalized" string

getObjectFromString

public java.lang.Object getObjectFromString(Record rec,
                                            java.lang.String s)
                                     throws DataException

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.

DataException

checkValidValue

public void checkValidValue(Record rec,
                            java.lang.Object value)
                     throws DataException

Note that the min-max interval is [min, max) following python range semantics.

Specified by:

checkValidValue in interface FieldDescriptor

Overrides:

checkValidValue in class Field

DataException
