public DateMetaInputModule()
Method Detail

configure

public void configure(Configuration config)
               throws ConfigurationException
Description copied from class: AbstractInputModule
Configures the database access helper. Takes all elements nested in component declaration and stores them as key-value pairs in settings. Nested configuration option are not catered for. This way global configuration options can be used. For nested configurations override this function.

Specified by:
configure in interface Configurable
Overrides:
configure in class AbstractInputModule
Throws:
ConfigurationException

getAttributeValues

public Object[] getAttributeValues(String name,
                                   Configuration modeConf,
                                   Map objectModel)
                            throws ConfigurationException
Description copied from interface: InputModule
Returns an array of String objects containing all of the values the given attribute has, or null if the attribute does not exist. As an alternative, InputModule.getAttributeNames(Configuration, Map) together with InputModule.getAttribute(String, Configuration, Map) can be used to get the values one by one.

Specified by:
getAttributeValues in interface InputModule
Overrides:
getAttributeValues in class AbstractInputModule
Parameters:
name - a String that specifies what the caller thinks would identify an attributes. This is mainly a fallback if no modeConf is present.
modeConf - column's mode configuration from resource description. This argument is optional.
Throws:
ConfigurationException

getAttributeNames

public Iterator getAttributeNames(Configuration modeConf,
                                  Map objectModel)
                           throws ConfigurationException
Description copied from interface: InputModule
Returns an Iterator of String objects containing the names of the attributes available. If no attributes are available, the method returns an empty Iterator.

Specified by:
getAttributeNames in interface InputModule
Overrides:
getAttributeNames in class AbstractInputModule
Parameters:
modeConf - column's mode configuration from resource description. This argument is optional.
Throws:
ConfigurationException

getAttribute

public Object getAttribute(String name,
                           Configuration modeConf,
                           Map objectModel)
                    throws ConfigurationException
Description copied from interface: InputModule
Standard access to an attribute's value. If more than one value exists, the first is returned. If the value does not exist, null is returned. To get all values, use InputModule.getAttributeValues(String, Configuration, Map) or InputModule.getAttributeNames(Configuration, Map) and InputModule.getAttribute(String, Configuration, Map) to get them one by one.

Specified by:
getAttribute in interface InputModule
Overrides:
getAttribute in class AbstractInputModule
Parameters:
name - a String that specifies what the caller thinks would identify an attribute. This is mainly a fallback if no modeConf is present.
modeConf - column's mode configuration from resource description. This argument is optional.
Throws:
ConfigurationException
