BundleSpecificationImpl

public BundleSpecificationImpl()

Method Detail

setExported

protected void setExported(boolean exported)

setOptional

protected void setOptional(boolean optional)

isExported

public boolean isExported()

Description copied from interface: BundleSpecification

Returns whether or not this bundle specificiation is exported from the declaring bundle.

Specified by:

isExported in interface BundleSpecification

Returns:

whether this specification is exported

isOptional

public boolean isOptional()

Description copied from interface: BundleSpecification

Returns whether or not this bundle specificiation is optional.

Specified by:

isOptional in interface BundleSpecification

Returns:

whether this specification is optional

isSatisfiedBy

public boolean isSatisfiedBy(BaseDescription supplier)

Description copied from interface: VersionConstraint

Returns whether this constraint could be satisfied by the given supplier. This will depend on the suppliers different attributes including its name, versions and other arbitrary attributes

Specified by:

isSatisfiedBy in interface VersionConstraint

Parameters:

supplier - a supplier to be tested against this constraint (may be null)

Returns:

true if this constraint could be resolved using the supplier, false otherwise

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getName

public java.lang.String getName()

Description copied from interface: VersionConstraint

Returns this constraint's name.

Specified by:

getName in interface VersionConstraint

Returns:

this constraint's name

getVersionRange

public VersionRange getVersionRange()

Description copied from interface: VersionConstraint

Returns the version range for this constraint.

Specified by:

getVersionRange in interface VersionConstraint

Returns:

the version range for this constraint, or null

getBundle

public BundleDescription getBundle()

Description copied from interface: VersionConstraint

Returns the bundle that declares this constraint.

Specified by:

getBundle in interface VersionConstraint

Returns:

a bundle description

isResolved

public boolean isResolved()

Description copied from interface: VersionConstraint

Returns whether this constraint is resolved. A resolved constraint is guaranteed to have its supplier defined.

Specified by:

isResolved in interface VersionConstraint

Returns:

true if this bundle is resolved, false otherwise

getSupplier

public BaseDescription getSupplier()

Description copied from interface: VersionConstraint

Returns the supplier that satisfies this constraint, if it is resolved.
