getCapabilities

public java.util.List<Capability> getCapabilities(java.lang.String namespace)

Description copied from interface: BundleRevision

Returns the capabilities declared by this resource.

This method returns the same value as BundleRevision.getDeclaredCapabilities(String).

Specified by:

getCapabilities in interface BundleRevision

Specified by:

getCapabilities in interface Resource

Parameters:

namespace - The namespace of the declared capabilities to return or null to return the declared capabilities from all namespaces.

Returns:

An unmodifiable list containing the declared Capabilitys from the specified namespace. The returned list will be empty if this resource declares no capabilities in the specified namespace.

asCapabilityList

private static java.util.List<Capability> asCapabilityList(java.util.List caps)

getDeclaredCapabilities

public java.util.List<BundleCapability> getDeclaredCapabilities(java.lang.String namespace)

Description copied from interface: BundleRevision

Returns the capabilities declared by this bundle revision.

Specified by:

getDeclaredCapabilities in interface BundleRevision

Parameters:

namespace - The namespace of the declared capabilities to return or null to return the declared capabilities from all namespaces.

Returns:

An unmodifiable list containing the declared BundleCapabilitys from the specified namespace. The returned list will be empty if this bundle revision declares no capabilities in the specified namespace. The list contains the declared capabilities in the order they are specified in the manifest.

getRequirements

public java.util.List<Requirement> getRequirements(java.lang.String namespace)

Description copied from interface: BundleRevision

Returns the requirements declared by this bundle resource.

This method returns the same value as BundleRevision.getDeclaredRequirements(String).

Specified by:

getRequirements in interface BundleRevision

Specified by:

getRequirements in interface Resource

Parameters:

namespace - The namespace of the declared requirements to return or null to return the declared requirements from all namespaces.

Returns:

An unmodifiable list containing the declared Requirement s from the specified namespace. The returned list will be empty if this resource declares no requirements in the specified namespace.

asRequirementList

private static java.util.List<Requirement> asRequirementList(java.util.List reqs)

getDeclaredRequirements

public java.util.List<BundleRequirement> getDeclaredRequirements(java.lang.String namespace)

Description copied from interface: BundleRevision

Returns the requirements declared by this bundle revision.

Specified by:

getDeclaredRequirements in interface BundleRevision

Parameters:

namespace - The namespace of the declared requirements to return or null to return the declared requirements from all namespaces.

Returns:

An unmodifiable list containing the declared BundleRequirements from the specified namespace. The returned list will be empty if this bundle revision declares no requirements in the specified namespace. The list contains the declared requirements in the order they are specified in the manifest.

getTypes

public int getTypes()

Description copied from interface: BundleRevision

Returns the special types of this bundle revision. The bundle revision type values are:

• BundleRevision.TYPE_FRAGMENT

If this bundle revision is not one or more of the defined types then 0 is returned.

Specified by:

getTypes in interface BundleRevision

Returns:

The special types of this bundle revision. The type values are ORed together.

getWiring

public BundleWiring getWiring()
