GenericSpecificationImpl

public GenericSpecificationImpl()

Method Detail

getMatchingFilter

public java.lang.String getMatchingFilter()

Description copied from interface: GenericSpecification

Returns a matching filter used to match with a suppliers attributes

Specified by:

getMatchingFilter in interface GenericSpecification

Returns:

a matching filter used to match with a suppliers attributes

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

getType

public java.lang.String getType()

Description copied from interface: GenericSpecification

Returns the type of generic specification

Specified by:

getType in interface GenericSpecification

Returns:

the type of generic specification

getResolution

public int getResolution()

Description copied from interface: GenericSpecification

Returns the resolution type of the required capability. The returned value is a bit mask that may have the optional bit GenericSpecification.RESOLUTION_OPTIONAL and/or the multiple bit GenericSpecification.RESOLUTION_MULTIPLE set.

Specified by:

getResolution in interface GenericSpecification

Returns:

the resolution type of the required capability

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.

Specified by:

getSupplier in interface VersionConstraint

Returns:

a supplier, or null

See Also:

VersionConstraint.isResolved()

setSupplier

protected void setSupplier(BaseDescription supplier)

getSuppliers

public GenericDescription[] getSuppliers()

Description copied from interface: GenericSpecification

Returns the suppliers of the capability. If the the resolution is multiple then more than one supplier may be returned

Specified by:

getSuppliers in interface GenericSpecification

Returns:

the suppliers of the capability

getInternalDirectives

protected java.util.Map<java.lang.String,java.lang.String> getInternalDirectives()

getInteralAttributes

protected java.util.Map<java.lang.String,java.lang.Object> getInteralAttributes()

getInternalNameSpace

protected java.lang.String getInternalNameSpace()

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

setName

protected void setName(java.lang.String name)

setVersionRange

protected void setVersionRange(VersionRange versionRange)

setBundle

protected void setBundle(BundleDescription bundle)

getRequirement

public BundleRequirement getRequirement()

Description copied from interface: VersionConstraint

Returns the requirement represented by this constraint. Some constraint types may not be able to represent a requirement. In such cases null is returned.

Specified by:

getRequirement in interface VersionConstraint

Returns:

the requirement represented by this constraint
