Field Detail
-
CAPABILITY_USES_DIRECTIVE
public static final String CAPABILITY_USES_DIRECTIVE
The capability directive used to specify the comma separated list of package names used by a capability.- See Also:
- Constant Field Values
-
CAPABILITY_EFFECTIVE_DIRECTIVE
public static final String CAPABILITY_EFFECTIVE_DIRECTIVE
The capability directive used to specify the effective time for the capability. The default value isresolve
.- See Also:
resolve
,active
, Constant Field Values
-
REQUIREMENT_FILTER_DIRECTIVE
public static final String REQUIREMENT_FILTER_DIRECTIVE
The requirement directive used to specify a capability filter. This filter is used to match against a capability's attributes.- See Also:
- Constant Field Values
-
REQUIREMENT_RESOLUTION_DIRECTIVE
public static final String REQUIREMENT_RESOLUTION_DIRECTIVE
The requirement directive used to specify the resolution type for a requirement. The default value ismandatory
.- See Also:
mandatory
,optional
, Constant Field Values
-
RESOLUTION_MANDATORY
public static final String RESOLUTION_MANDATORY
The directive value identifying a mandatory requirement resolution type. A mandatory resolution type indicates that the requirement must be resolved when the resource is resolved. If such a requirement cannot be resolved, the resource fails to resolve.
-
RESOLUTION_OPTIONAL
public static final String RESOLUTION_OPTIONAL
The directive value identifying an optional requirement resolution type. An optional resolution type indicates that the requirement is optional and the resource may be resolved without the requirement being resolved.
-
REQUIREMENT_EFFECTIVE_DIRECTIVE
public static final String REQUIREMENT_EFFECTIVE_DIRECTIVE
The requirement directive used to specify the effective time for the requirement. The default value isresolve
.- See Also:
resolve
,active
, Constant Field Values
-
EFFECTIVE_RESOLVE
public static final String EFFECTIVE_RESOLVE
The directive value identifying acapability
orrequirement
that is effective at resolve time. Capabilities and requirements with an effective time of resolve are the only capabilities which are processed while resolving a resource.
-
EFFECTIVE_ACTIVE
public static final String EFFECTIVE_ACTIVE
The directive value identifying acapability
orrequirement
that is effective at active time. Capabilities and requirements with an effective time of active are ignored while resolving a resource.
-
REQUIREMENT_CARDINALITY_DIRECTIVE
public static final String REQUIREMENT_CARDINALITY_DIRECTIVE
The requirement directive used to specify the cardinality for a requirement. The default value issingle
.- See Also:
multiple
,single
, Constant Field Values
-
CARDINALITY_MULTIPLE
public static final String CARDINALITY_MULTIPLE
The directive value identifying a multiplecardinality
type.
-
CARDINALITY_SINGLE
public static final String CARDINALITY_SINGLE
The directive value identifying acardinality
type of single.
