Interface ExecutionEnvironmentResolutionHints

public interface ExecutionEnvironmentResolutionHints
Settings for supporting resolution for a dedicated execution environment. Handles p2's "a.jre" installable units representing the capabilities of the JRE or custom profiles. Types implementing this interface shall be immutable and provide reasonable implementations for equals(Object) and hashCode().

    getTemporaryAdditions()
    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.

  • Method Details

    • isEESpecificationUnit

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

    • isNonApplicableEEUnit

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

    • getMandatoryUnits

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

    • getMandatoryRequires

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

    • getTemporaryAdditions

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