Constructor Detail

StandardEEResolutionHints

public StandardEEResolutionHints(java.lang.String executionEnvironment)

Method Detail

isNonApplicableEEUnit

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

p2 repositories are polluted with useless a.jre/config.a.jre IUs. These IUs do not represent current/desired JRE and can expose resolver to packages that are not actually available.

Specified by:

isNonApplicableEEUnit in interface ExecutionEnvironmentResolutionHints

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

computeAdditionalUnits

private static java.util.Map<org.eclipse.equinox.p2.metadata.VersionedId,org.eclipse.equinox.p2.metadata.IInstallableUnit> computeAdditionalUnits(java.lang.String executionEnvironment)

Return IUs that represent packages provided by target JRE

Parameters:

executionEnvironment -

addIUsFromEnvironment

static void addIUsFromEnvironment(java.lang.String executionEnvironment,
                                  java.util.Map<org.eclipse.equinox.p2.metadata.VersionedId,org.eclipse.equinox.p2.metadata.IInstallableUnit> units)

ensureEEWasKnownToJREAction

private static void ensureEEWasKnownToJREAction(java.lang.String executionEnvironment,
                                                java.util.Collection<org.eclipse.equinox.p2.metadata.IInstallableUnit> eeUnits)

getMandatoryUnits

public java.util.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 java.util.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

computeTemporaryAdditions

private java.util.Map<org.eclipse.equinox.p2.metadata.VersionedId,org.eclipse.equinox.p2.metadata.IInstallableUnit> computeTemporaryAdditions(java.util.Map<org.eclipse.equinox.p2.metadata.VersionedId,org.eclipse.equinox.p2.metadata.IInstallableUnit> additionalUnits)

removeExportedPackages

private static org.eclipse.equinox.p2.metadata.IInstallableUnit removeExportedPackages(org.eclipse.equinox.p2.metadata.IInstallableUnit initialUnit)

getTemporaryAdditions

public java.util.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

put

private static void put(java.util.Map<org.eclipse.equinox.p2.metadata.VersionedId,org.eclipse.equinox.p2.metadata.IInstallableUnit> units,
                        org.eclipse.equinox.p2.metadata.IInstallableUnit unit)

hashCode

public int hashCode()

Specified by:

hashCode in interface ExecutionEnvironmentResolutionHints

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object obj)

Specified by:

equals in interface ExecutionEnvironmentResolutionHints

Overrides:

equals in class java.lang.Object

eq

private static <T> boolean eq(T left,
