computeDependencies

public org.eclipse.equinox.p2.query.IQueryResult<org.eclipse.equinox.p2.metadata.IInstallableUnit> computeDependencies(Collection<org.eclipse.equinox.p2.metadata.IInstallableUnit> rootIus,
 org.eclipse.equinox.p2.query.IQueryable<org.eclipse.equinox.p2.metadata.IInstallableUnit> avaiableIUs,
 SlicingOptions options)
                                                                                                                throws org.eclipse.core.runtime.CoreException

Computes a "slice" of a given set of IInstallableUnits that include as much of the requirements of the root units that are fulfilled by the available units. The slice is greedy, that means that as much as possible is included.

Parameters:

rootIus - the root units that are inspected for the slice

avaiableIUs - the IQueryable of all units that could be used for the slice

options - the options used for the slicing

Returns:

the result of the slicing

Throws:

org.eclipse.core.runtime.CoreException - if there is any error

computeDirectDependencies

public Map<org.eclipse.equinox.p2.metadata.IRequirement,Collection<org.eclipse.equinox.p2.metadata.IInstallableUnit>> computeDirectDependencies(Collection<org.eclipse.equinox.p2.metadata.IInstallableUnit> rootIus,
 org.eclipse.equinox.p2.query.IQueryable<org.eclipse.equinox.p2.metadata.IInstallableUnit> avaiableIUs)
                                                                                                                                         throws org.eclipse.core.runtime.CoreException

Computes a "slice" that is the direct dependencies of the given IInstallableUnits in a way that the result contains any unit that satisfies a requirement in for rootIus

Parameters:

rootIus - the root InstallableUnits to take into account

avaiableIUs - the IQueryable of all units that could be used for fulfilling a requirement

contextIUs - context IUs that represent the the profile properties to consider during resolution, can be empty in which case a filter is always considered a match

Returns:

the result of the slicing, be aware that no maximum/minimum constraints or filters are applied as part of this computation

Throws:

org.eclipse.core.runtime.CoreException - if there is any error
