Class: PropertyFilter

new $k.PropertyFilter(filterDescriptoropt)

Creates a new PropertyFilter. If the constructer is called as a function, it will construct a new filter, too.

Parameters:

Name Type Attributes Description

filterDescriptor

object

If the parameter is omitted, the default values will be used.

Properties

Name	Type	Attributes	Default	Description
`type`	$k.PropertyType \| string	<optional>		Property type or internal name
`abstract`	boolean	<optional>	false	Include abstract properties
`exact`	boolean	<optional>	false	Exclude sub types of the specified properties
`attributes`	boolean	<optional>	true	Include attributes
`userRelations`	boolean	<optional>	true	Include user relations
`oneWayRelations`	boolean	<optional>	false	Include the virtual inverse relations of one way relations pointing to the object
`shortcutRelations`	boolean	<optional>	false	Include shortcut relations
`systemRelations`	boolean	<optional>	false	Include system relations
`unconstrained`	boolean	<optional>	false	When querying possible properties with this filter, include properties that cannot actually be created due to cardinality constraints (e.g. an attribute that already exists and does not allow multiple occurrences)

Example

// Returns a filter that returns properties with internal name "contains"
$k.PropertyFilter({ exact: true, type: "contains" });

includeSystemRelations() → {boolean}

Returns true if system relations should be returned

Returns:

Type:: boolean

includeUserRelations() → {boolean}

Returns true if user relations should be returned

Returns:

Type:: boolean

isExact() → {boolean}

Returns true if only properties of the specified type should be returned, false if also sub-properties should be included

Returns:

Type:: boolean

possiblePropertiesOf(object) → {Array.<$k.PropertyType>}

Returns the possible properties of the semantic element / domain

Parameters:

Name	Type	Description
`object`	$k.SemanticElement \| $k.Domain	Semantic element or domain

Returns:

Type:: Array.<$k.PropertyType>

propertiesOf(semanticElement) → {Array.<$k.PropertyType>}

Returns the properties of the semantic element

Parameters:

Name	Type	Description
`semanticElement`	$k.SemanticElement

Returns:

Type:: Array.<$k.PropertyType>

setAbstract(abstractopt) → {$k.PropertyFilter}

Defines if abstract properties are returned

Parameters:

Name	Type	Attributes	Default	Description
`abstract`	boolean	<optional>	true

Returns:

The filter

Type:: $k.PropertyFilter

setAttributes(attributesopt) → {$k.PropertyFilter}

Defines if attributes should be returned

Parameters:

Name	Type	Attributes	Default	Description
`attributes`	boolean	<optional>	true

Returns:

The filter

Type:: $k.PropertyFilter

setExact(exactopt) → {$k.PropertyFilter}

Defines if only properties of the specified type should be returned, or also sub-properties

Parameters:

Name	Type	Attributes	Default	Description
`exact`	boolean	<optional>	true

Returns:

The filter

Type:: $k.PropertyFilter

setOneWayRelations(oneWayRelationsopt) → {$k.PropertyFilter}

Defines if inverse one way relations should be returned

Parameters:

Name	Type	Attributes	Default	Description
`oneWayRelations`	boolean	<optional>	true

Returns:

The filter

Type:: $k.PropertyFilter

setShortcutRelations(shortcutRelationsopt) → {$k.PropertyFilter}

Defines if shortcut relations should be returned

Parameters:

Name	Type	Attributes	Default	Description
`shortcutRelations`	boolean	<optional>	true

Returns:

The filter

Type:: $k.PropertyFilter

setSystemRelations(systemRelationsopt) → {$k.PropertyFilter}

Defines if shortcut relations should be returned

Parameters:

Name	Type	Attributes	Default	Description
`systemRelations`	boolean	<optional>	true

Returns:

The filter

Type:: $k.PropertyFilter

setType(type) → {$k.PropertyFilter}

Defines the type / internal name of the properties

Parameters:

Name	Type	Description
`type`	$k.PropertyType \| string	Type or internal name

Returns:

The filter

Type:: $k.PropertyFilter

setUnconstrained(additionalOnlyopt) → {$k.PropertyFilter}

Defines if properties should be returned that cannot be created due to cardinality constrains. This setting only has an effect when quering the possible properties of a semantic element, not of a domain.

Parameters:

Name	Type	Attributes	Default	Description
`additionalOnly`	boolean	<optional>	true

Returns:

The filter

Type:: $k.PropertyFilter

setUserRelations(userRelationsopt) → {$k.PropertyFilter}

Defines if user relations should be returned

Parameters:

Name	Type	Attributes	Default	Description
`userRelations`	boolean	<optional>	true

Returns:

The filter

Type:: $k.PropertyFilter

toPropertyFilter() → {$k.PropertyFilter}

Returns this filter. To define custom property filters, define an object with a function toPropertyFilter(). If toPropertyFilter() does not return an object of kind $k.PropertyFilter, the object has to define the functions propertiesOf() and possiblePropertiesOf()

Returns:

Type:: $k.PropertyFilter

type() → {$k.PropertyType|string}

Returns the type / internal name that should be used for filtering properties

Returns:

Type:: $k.PropertyType | string

unconstrained() → {boolean}

Returns true if properties should be returned that cannot be created due to cardinality constrains. This setting only has an effect when quering the possible properties of a semantic element, not of a domain. Default is false

Returns:

Type:: boolean
