getType in class Attribute

Returns:

"number"

isValidRule

public boolean isValidRule(java.lang.String ruleName)

Description copied from interface: Filterable

convertRule

public Filterable.Rule convertRule(java.lang.String unparsedRule,
                                   java.util.List unparsedValues,
                                   ErrorWriter err)
                            throws BadDataException

Description copied from class: Attribute

convertRule in interface Filterable

Overrides:

convertRule in class Attribute

Parameters:

unparsedRule - the rule to convert

unparsedValues - the values

err - the error stream

Returns:

the rule for this attribute
