RenderVariableBinding

public RenderVariableBinding(Location location,
                             String description,
                             ComponentResources resources,

Method Detail

set

public void set(Object value)

Description copied from interface: Binding

Updates the current value. Most types of bindings are read-only, and this method will throw a runtime exception. It is the caller's responsibility to ensure that the value passed in is of the appropriate type.

Specified by:

set in interface Binding

Overrides:

set in class AbstractBinding

isInvariant

public boolean isInvariant()

Returns false, render variables are always variable.

Specified by:

isInvariant in interface Binding

Overrides:

isInvariant in class AbstractBinding

toString

public String toString()

Overrides:

toString in class Object

get

public Object get()

Description copied from interface: Binding

Reads the current value of the property (or other resource). When reading properties of objects that are primitive types, this will return an instance of the wrapper type. In some cases, a binding is read only and this method will throw a runtime exception.

getBindingType

public Class getBindingType()

Always returns Object since we don't (statically) know the type of object.

Specified by:

getBindingType in interface Binding

Overrides:

getBindingType in class AbstractBinding
