Constructor Detail

NewPrefixesQuery

public NewPrefixesQuery(Composite parent,
                        Set<String> namespaces,
                        NamespaceManager nsManager)

Constructs the component.

Parameters:

parent - the parent composite.

namespaces - get prefixes for these namespaces.

nsManager - current namespace manager. New prefixes are not registered here, new manager is created instead.

Method Detail

getComposite

public Composite getComposite()

Description copied from interface: IUserInputWidget

Returns composite that is encapsulated in this object.

Returns:

composite where all controls are placed.

getPrefixes

public Map<String,String> getPrefixes()

Returns currently selected prefixes.

Returns:

map that maps namespace URI to prefix, never null.

getPrefixesInternal

public Map<String,String> getPrefixesInternal()

Returns currently selected prefixes. Does not check for errors.

Returns:

map that maps namespace URI to prefix, never null.

getNamespaces

public static Set<String> getNamespaces(List<? extends QName> qnames)

Returns all namespaces that occurs in given list. Empty namespace is not in the result set - this is because empty namespace does not have prefix in EuroMath2.

Parameters:

qnames - set of qnames. nulls are permitted - they are simply ignored.

Returns:

all namespaces in given list.

newUpdatedManager

public NamespaceManager newUpdatedManager()

Produces a namespace manager where these new prefixes are registered.

Returns:

namespace manager containing new prefix mappings.

Throws:

IllegalArgumentException - if the page contains errors thus some prefixes cannot be registered.

IllegalStateException - if the page contains errors thus some prefixes cannot be registered.

getMessages

public ValidityMessages getMessages()

Description copied from interface: IUserInputWidget

Checks if data contained in the widget are correct. Contains error/info/warning messages that occured during last data change.

Returns:

null if data is correct, or instance of ValidityMessages if there is error, warning or info message.

checkErrors

protected void checkErrors(Map<String,String> map)

Checks data for errors.

Parameters:

map - map that maps namespace URI to prefix, must not be null.

setPrefixes

public List<QName> setPrefixes(List<QName> qnames)

Modifies the prefixes of all qnames to currently selected prefixes.

Parameters:

qnames - list of qnames to modify

Returns:

modified qnames

getState

public Map<String,String> getState()

Description copied from interface: IUserInputWidget

Returns the state of this widget. The state must be in sync with the controls placed on the widget.

Returns:

the model.

getStateClass

public Class<?> getStateClass()

Description copied from interface: IUserInputWidget

Returns the class of the state that the widget accepts.

Returns:

model class, never null.

setState

public void setState(Object state)

Description copied from interface: IUserInputWidget

Sets new state for the widget. The widget must re-read all relevant properties from the state and set its controls with new values.

Parameters:

state - the model to set. You may use the construct setModel(getModel()) to reflect changes made in the model. Please note that nearly all widgets rejects null value.
