Constructor Detail

StringBufferView

public StringBufferView(WidgetModel model)

Creates a new StringBufferView instance.

Parameters:

model - a WidgetModel value

Method Detail

addTokens

public void addTokens(Map<Object,Object> props)

Adds all the name/value pairs and then updates the model. If the named token already exists, replace the value. This is more efficient than many calls to setToken(), because model.getCurrentModel is only called once.

Specified by:

addTokens in interface WidgetView

Parameters:

props - a Map value

setToken

public void setToken(Object key,
                     Object value)

Sets the named token to the given value. Most tokens will be propegated to the backing model. Resets the StringBuffer's contents to model.getCurrentModel().toString().

Specified by:

setToken in interface WidgetView

Parameters:

key - an Object value

value - an Object value

getValue

public Object getValue(Object key)

Gets the value of the named token. Most values will be taken from the backing model.

Specified by:

getValue in interface WidgetView

Parameters:

key - an Object value

Returns:

an Object value

getModel

public WidgetModel getModel()

Returns the backing model.

Specified by:

getModel in interface WidgetView

Returns:

a WidgetModel value

setModel

public void setModel(WidgetModel newModel)

Sets the backing model.

Specified by:

setModel in interface WidgetView

Parameters:

newModel - a WidgetModel value

equals

public boolean equals(Object o)

Uses StringBuffer.equals() to test for equality.

Overrides:

equals in class Object

Parameters:

o - an Object value

Returns:

a boolean value

toString

public String toString()

Overrides:

toString in class Object
