Method Detail

definePropertyDescriptor

void definePropertyDescriptor(PropertyDescriptor<?> propertyDescriptor)
                              throws IllegalArgumentException

Define a new property via a PropertyDescriptor.

Parameters:

propertyDescriptor - The property descriptor.

Throws:

IllegalArgumentException - If there is already a property defined the same name.

getPropertyDescriptor

PropertyDescriptor<?> getPropertyDescriptor(String name)

Get the PropertyDescriptor for the given property name.

Parameters:

name - The name of the property.

Returns:

The PropertyDescriptor for the named property, null if there is no such property defined.

getPropertyDescriptors

List<PropertyDescriptor<?>> getPropertyDescriptors()

Get the PropertyDescriptors for all defined properties. The properties are returned sorted by UI order.

Returns:

The PropertyDescriptors in UI order.

getProperty

<T> T getProperty(PropertyDescriptor<T> propertyDescriptor)

Get the typed value for the given property.

Type Parameters:

T - The underlying type of the property descriptor.

Parameters:

propertyDescriptor - The property descriptor.

Returns:

The property value.

setProperty

<T> void setProperty(PropertyDescriptor<T> propertyDescriptor,
                   T value)

Set the property value specified (will be type-checked)

Type Parameters:

T - The underlying type of the property descriptor.

Parameters:

propertyDescriptor - The property descriptor.

value - The value to set.

getPropertiesByPropertyDescriptor

Map<PropertyDescriptor<?>,Object> getPropertiesByPropertyDescriptor()

Returns all the current property values for the receiver or an immutable empty map if none are specified.

Returns:

all current property values or a empty map.

hasDescriptor

boolean hasDescriptor(PropertyDescriptor<?> descriptor)

Returns whether this Rule has the specified PropertyDescriptor.

Parameters:

descriptor - The PropertyDescriptor for which to check.

Returns:

boolean true if the descriptor is present, false otherwise.

usesDefaultValues

boolean usesDefaultValues()

Returns whether this Rule uses default values for properties.

Returns:

boolean true if the properties all have default values, false otherwise.

useDefaultValueFor

void useDefaultValueFor(PropertyDescriptor<?> desc)

Clears out any user-specified value for the property allowing it to use the default value in the descriptor.

Parameters:

desc - the property to clear out

ignoredProperties

Set<PropertyDescriptor<?>> ignoredProperties()

Return the properties that are effectively ignored due to the configuration of the rule and values held by other properties. This can be used to disable corresponding widgets in a UI.

Returns:

the properties that are ignored

dysfunctionReason

String dysfunctionReason()

Returns a description of why the receiver may be dysfunctional. Usually due to missing property values or some kind of conflict between values. Returns null if the receiver is ok.

Returns:

String
