public abstract class Namespace
extends Object

Capability and Requirement Namespaces base class.

This class is the common class shared by all OSGi defined namespaces. It defines the names for the common attributes and directives for the OSGi specified namespaces.

The OSGi Alliance reserves the right to extend the set of directives and attributes which have specified semantics for all of the specified namespaces.

The values associated with these keys are of type String, unless otherwise indicated.

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 is resolve.

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 is mandatory .

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.

See Also:

REQUIREMENT_RESOLUTION_DIRECTIVE, Constant Field Values

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.

See Also:

REQUIREMENT_RESOLUTION_DIRECTIVE, Constant Field Values

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 is resolve.

See Also:

resolve, active, Constant Field Values

EFFECTIVE_RESOLVE

public static final String EFFECTIVE_RESOLVE

The directive value identifying a capability or requirement 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.

See Also:

REQUIREMENT_EFFECTIVE_DIRECTIVE, CAPABILITY_EFFECTIVE_DIRECTIVE, Constant Field Values

EFFECTIVE_ACTIVE

public static final String EFFECTIVE_ACTIVE

The directive value identifying a capability or requirement that is effective at active time. Capabilities and requirements with an effective time of active are ignored while resolving a resource.

See Also:

REQUIREMENT_EFFECTIVE_DIRECTIVE, CAPABILITY_EFFECTIVE_DIRECTIVE, Constant Field Values

REQUIREMENT_CARDINALITY_DIRECTIVE

public static final String REQUIREMENT_CARDINALITY_DIRECTIVE

The requirement directive used to specify the cardinality for a requirement. The default value is single.

See Also:

multiple, single, Constant Field Values

CARDINALITY_MULTIPLE

public static final String CARDINALITY_MULTIPLE

The directive value identifying a multiple cardinality type.

See Also:

REQUIREMENT_CARDINALITY_DIRECTIVE, Constant Field Values

CARDINALITY_SINGLE

public static final String CARDINALITY_SINGLE

The directive value identifying a cardinality type of single.

See Also:

REQUIREMENT_CARDINALITY_DIRECTIVE, Constant Field Values
