Enum Constant Summary

Enum Constants

Enum Constant	Description
DynamicImport	Represents an unresolved package referenced by Dynamic-ImportPackage.
FragmentNotSelected	Represents the scenario where a fragment matches a host but is not selected because another fragment with the same Bundle-SymbolicName already matched, usually a fragment of a higher version.
MissingRequirement	Represents the scenario where a requirement could not be resolved.
UseConstraint	Represents a failure in the use constraints of a bundle.

Enum Constant Details

DynamicImport

public static final ReasonException.Reason DynamicImport

Represents an unresolved package referenced by Dynamic-ImportPackage.

ResolutionException.getUnresolvedRequirements() will return a collection containing the single osgi.wiring.package;resolution:=dynamic requirement which failed to resolve.

This reason has no a transitive cause.

FragmentNotSelected

public static final ReasonException.Reason FragmentNotSelected

Represents the scenario where a fragment matches a host but is not selected because another fragment with the same Bundle-SymbolicName already matched, usually a fragment of a higher version.

ResolutionException.getUnresolvedRequirements() will return a collection containing the single osgi.wiring.host requirement of the fragment.

This reason has no a transitive cause.

MissingRequirement

public static final ReasonException.Reason MissingRequirement

Represents the scenario where a requirement could not be resolved.

ResolutionException.getUnresolvedRequirements() will return a collection containing a single requirement that didn't resolve.

This reason may have a transitive cause.

UseConstraint

public static final ReasonException.Reason UseConstraint

Represents a failure in the use constraints of a bundle.

ResolutionException.getUnresolvedRequirements() will return a collection containing a single requirement to blame for the use constraint violation.

This reason has no a transitive cause.

Method Details

values

public static ReasonException.Reason[] values()

Returns an array containing the constants of this enum type, in the order they are declared.

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static ReasonException.Reason valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
