HostSpecificationImpl

public HostSpecificationImpl()

Method Detail

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

getHosts

public BundleDescription[] getHosts()

Description copied from interface: HostSpecification

Returns the list of host BundleDescriptions that satisfy this HostSpecification

Specified by:

getHosts in interface HostSpecification

Returns:

the list of host BundleDescriptions that satisfy this HostSpecification

hasMandatoryAttributes

protected boolean hasMandatoryAttributes(String[] mandatory)

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

toString

public String toString()

Overrides:

toString in class Object

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

VersionConstraint.isResolved()

isMultiHost

public boolean isMultiHost()

Description copied from interface: HostSpecification

Returns if this HostSpecification is allowed to have multiple hosts

Specified by:

isMultiHost in interface HostSpecification

Returns:

true if this HostSpecification is allowed to have multiple hosts

getInternalDirectives

protected Map<String,String> getInternalDirectives()

getInteralAttributes

protected Map<String,Object> getInteralAttributes()

getInternalNameSpace

protected String getInternalNameSpace()

getName

public String getName()

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(String name)

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

getUserObject

public Object getUserObject()

Description copied from interface: VersionConstraint

Returns the user object associated to this constraint, or null if none exists.

Specified by:

getUserObject in interface VersionConstraint

Returns:

the user object associated to this constraint, or null

setUserObject

public void setUserObject(Object userObject)

Description copied from interface: VersionConstraint

Associates a user-provided object to this constraint, or removes an existing association, if null is provided. The provided object is not interpreted in any ways by this constrain.

Specified by:

setUserObject in interface VersionConstraint

Parameters:

userObject - an arbitrary object provided by the user, or null
