Interface DependencyDescriptor

All Superinterfaces:
ExtendableItem, InheritableItem
All Known Implementing Classes:
DefaultDependencyDescriptor

public interface DependencyDescriptor
extends ExtendableItem, InheritableItem

Describes a dependency from a depender to a dependee.

The main information this descriptor contains is the constraint on the dependency. There is actually two kind of dependency constraints: the default dependency constraint, which can be obtained with getDependencyRevisionId(), and corresponds to the rev attribute in Ivy files. This is the constraint as it should be honored by Ivy in default resolve mode.

Then there is the dynamic constraint, which can either be the same as the default constraint, or the original dependency constraint when an Ivy file is delivered an published to a repository. This dynamic constraint is returned by getDynamicConstraintDependencyRevisionId(), and corresponds to the revconstraint attribute in the Ivy file. In some resolve mode, this constraint can be used instead of the default dependency constraint when performing dependency resolution.

Method Detail

getDependencyId

ModuleId getDependencyId()

isForce

boolean isForce()
Used to indicate that this revision must be used in case of conflicts, independently of conflicts manager. This only works for direct dependencies, and not transitive ones.

Returns:
true if this dependency should be used, false if conflicts manager can do its work.

isChanging

boolean isChanging()
Used to indicate that this dependency is a changing one. A changing dependency in ivy means that the revision may have its artifacts modified without revision change. When new artifacts are published a new ivy file should also be published with a new publication date to indicate to ivy that artifacts have changed and that they should be downloaded again.

Returns:
true if this dependency is a changing one

isTransitive

boolean isTransitive()

getParentRevisionId

ModuleRevisionId getParentRevisionId()

getDependencyRevisionId

ModuleRevisionId getDependencyRevisionId()
Returns the constraint on dependency this descriptor represents.

Returns:
the constraint on dependency.

getDynamicConstraintDependencyRevisionId

ModuleRevisionId getDynamicConstraintDependencyRevisionId()
Returns the dynamic constraint on dependency this descriptor represents.

Returns:
the dynamic constraint on dependency, or exact constraint if no dynamic constraint is specified.

getDependencyConfigurations

                    ArtifactId artifactId)
Returns true if

Parameters:

Returns:

canExclude

boolean canExclude()
Returns true if this descriptor contains any exclusion rule

Returns:
true if this descriptor contains any exclusion rule

asSystem

DependencyDescriptor asSystem()

clone

DependencyDescriptor clone(ModuleRevisionId revision)
Clones current dependency descriptor with another revision.

Parameters:
revision - the revision of the cloned dependency descriptor
Returns:
the cloned dependency descriptor
Throws:
java.lang.IllegalArgumentException - if the given ModuleRevisionId has not the same ModuleId as the ModuleRevisionId of this descriptor.
