 String elementName,
 @ResourceName
 URI resourceName)

Overrides:

startElement in class AbstractComponentHandler<T extends LabeledComponent & DataComponent>

public final void setDataType(String dataType)
                       throws ModelBuildException

Throws:

@Attribute("constriction")
public void setConstriction(String constriction)

@Attribute("default-lang-only")
public final void setDefaultLangOnly(boolean flag)

setIgnoreCopy

@Attribute("ignore-copy")
public final void setIgnoreCopy(boolean ignoreCopy)

setEventHandler

@Attribute("event-handler")
public final void setEventHandler(String eventHandler)

addValidations

@Element("validations")
@Cardinality(min=0,
             max=1)
public AndGroupValidatorModelHandler addValidations()
                                             throws ModelBuildException

Throws:

ModelBuildException

@Element("default")
@Cardinality(min=0,
             max=1)
public DefaultValueHandler addDefaultValues()
                                     throws ModelBuildException

Throws:

ModelBuildException

addAutoComplete

@Element("auto-complete")
@Cardinality(min=0,
             max=1)
public AutoCompleteHandler addAutoComplete()
                                    throws ModelBuildException

Throws:

ModelBuildException

beforeFinish

protected void beforeFinish()

Description copied from class: AbstractComponentHandler

Will be called before running the AbstractComponentHandler.finish()-Method this.field won't be available yet.

Overrides:

beforeFinish in class AbstractComponentHandler<T extends LabeledComponent & DataComponent>

See Also:

• AbstractComponentHandler.afterFinish()

afterFinish

protected void afterFinish()
                    throws ModelBuildException

Description copied from class: AbstractComponentHandler

Will be called after running the AbstractComponentHandler.finish()-Method. this.field will be ready to fill.

Overrides:

afterFinish in class AbstractComponentHandler<T extends LabeledComponent & DataComponent>

Throws:

ModelBuildException

See Also:

• AbstractComponentHandler.beforeFinish()

afterDataSet

protected abstract void afterDataSet()

Will be called at the or towards the end of afterFinish().

This is abstract so that every implementer is forced to know about its existence.

For an example see TextAreaHandler.afterDataSet(); it assigns additional, component-specific data read from xml to the component: field.setRowHeight(rowHeight);

getDefaultValidators

protected Iterable<Validator> getDefaultValidators()

Overridable getter for field handlers to return default validators.

This might be obsolete, because now, default validations come in based on data types.

For example the BirthDateFieldHandler returns a validator that checks for dates in the future. A ChZipcodeFieldHandler could return a validator that checks for a number range 1000-9999.

Returns:

May be empty but not null for easy iteration, not modifiable.

addValidator

public void addValidator(Validator validator)
                  throws IllegalArgumentException

This case only allows a AndGroupValidatorImpl, not just any validator!

Specified by:

addValidator in interface ValidatorReceivable

Parameters:

validator - .

Throws:

IllegalArgumentException - if a later validator uses a stronger error level than a previous one in the same group.

simpleSearch

@Attribute("simple-search")
public void simpleSearch(boolean simpleSearch)
