Method Detail

isEESpecificationUnit

public boolean isEESpecificationUnit(org.eclipse.equinox.p2.metadata.IInstallableUnit unit)

Description copied from interface: ExecutionEnvironmentResolutionHints

Returns true for the "a.jre" installable unit that contains the specification of the execution environment. This method is used for finding the specification unit of custom profiles.

Specified by:

isEESpecificationUnit in interface ExecutionEnvironmentResolutionHints

isNonApplicableEEUnit

public boolean isNonApplicableEEUnit(org.eclipse.equinox.p2.metadata.IInstallableUnit iu)

Description copied from interface: ExecutionEnvironmentResolutionHints

Returns true if an installable unit shall be removed from the available IUs. This prevents that "a.jre" IUs for the wrong execution environment are used for resolution.

Specified by:

isNonApplicableEEUnit in interface ExecutionEnvironmentResolutionHints

getMandatoryUnits

public Collection<org.eclipse.equinox.p2.metadata.IInstallableUnit> getMandatoryUnits()

Description copied from interface: ExecutionEnvironmentResolutionHints

Returns the list of installable units that shall be used during resolution. These units are added to the available units so that requirements of the capabilities of the execution environment can be resolved, and their use during resolution is enforced so that other units providing the same capabilities are not used (unless they are needed for other reasons).

Specified by:

getMandatoryUnits in interface ExecutionEnvironmentResolutionHints

getMandatoryRequires

public Collection<org.eclipse.equinox.p2.metadata.IRequirement> getMandatoryRequires()

Description copied from interface: ExecutionEnvironmentResolutionHints

Returns requirements to execution environment units to ensure that a) the execution environment units are available, and b) the units are used to the resolution result.

Specified by:

getMandatoryRequires in interface ExecutionEnvironmentResolutionHints

getTemporaryAdditions

public Collection<org.eclipse.equinox.p2.metadata.IInstallableUnit> getTemporaryAdditions()

Description copied from interface: ExecutionEnvironmentResolutionHints

Returns the list of installable units that shall be temporarily added to the list of installable units, i.e. they shall be available during resolution but must be removed from the resolution result.

Specified by:

getTemporaryAdditions in interface ExecutionEnvironmentResolutionHints
