Interface DatatypeValidator

public interface DatatypeValidator

DataTypeValidator defines the interface that data type validators must obey. These validators can be supplied by the application writer and may be useful as standalone code as well as plugins to the validator architecture. Note: there is no support for facets in this API, since we are trying to convince W3C to remove facets from the data type spec.

Method Detail

validate

public void validate(java.lang.String content)
              throws InvalidDatatypeValueException

validate that a string matches a datatype validate returns true or false depending on whether the string content is an instance of the data type represented by this validator.

Parameters:

content - A string containing the content to be validated

Throws:

throws - InvalidDatatypeException if the content is invalid according to the rules for the validators

setFacets

public void setFacets(java.util.Hashtable facets)
               throws UnknownFacetException,
                      IllegalFacetException,
                      IllegalFacetValueException

set the facets for this datatype setFacets is responsible for ensuring that the supplied facets do not contradict each other

Parameters:

facets - A hashtable where facet names are keys and facet values are stored in the hashtable. Usually facet values are strings, except for the enumeration facet. The value for this facet is a Vector of strings, one per enumeration value

Throws:

throws - UnknownFacetException

throws - IllegalFacetException

throws - IllegalFacetValueException

setBasetype

public void setBasetype(DatatypeValidator base)

set the base type for this datatype

Parameters:

base - the validator for this type's base type

setLocale

public void setLocale(java.util.Locale locale)

set the locate to be used for error messages
