  Constant Field Values

Method Detail

### isDefault

    boolean isDefault()

  Returns true if this descriptor is a default one, i.e. one generated for a module not actually having one.

  Returns:

### getModuleRevisionId

    ModuleRevisionId getModuleRevisionId()

### getResolvedModuleRevisionId

    ModuleRevisionId getResolvedModuleRevisionId()

  The module revision id returned here is the resolved one, i.e. it is never a latest one. If the revision has not been resolved, a null revision should be returned by getRevision() of the returned ModuleRevisionId. This revision must be the same as the module descriptor resolved revision id unless no module descriptor is defined

  Returns:

### setResolvedModuleRevisionId

    void setResolvedModuleRevisionId(ModuleRevisionId revId)

  This method update the resolved module revision id

  Parameters:
    `revId` -

### getInheritedDescriptors

    ExtendsDescriptor[] getInheritedDescriptors()

  Get the list of parent descriptors imported via an <extends> element. Only directly imported descriptors are included; the parent's parents are not included.

### setResolvedPublicationDate

    void setResolvedPublicationDate(java.util.Date publicationDate)

  This method update the resolved publication date

  Parameters:
    `publicationDate` -

### getStatus

    java.lang.String getStatus()

### getPublicationDate

    java.util.Date getPublicationDate()

  May be `null` if unknown in the descriptor itself.

  Returns:
    The publication date or `null` when not knwon.

### getResolvedPublicationDate

    java.util.Date getResolvedPublicationDate()

  The publication date of the module revision should be the date at which it has been published, i.e. in general the date of any of its published artifacts, since all published artifact of a module should follow the same publishing cycle.

### getConfigurations

    Configuration[] getConfigurations()

  Returns all the configurations declared by this module as an array. This array is never empty (a 'default' conf is assumed when none is declared in the ivy file)

  Returns:
    all the configurations declared by this module as an array.

### getConfigurationsNames

    java.lang.String[] getConfigurationsNames()

### getPublicConfigurationsNames

    java.lang.String[] getPublicConfigurationsNames()

### getArtifacts

    Artifact[] getArtifacts(java.lang.String conf)

### getAllArtifacts

    Artifact[] getAllArtifacts()

  Returns all artifacts of this module, excluding the artifact corresponding to the module descriptor.

  Returns:
    all published artifacts of this module
  See Also:
    `getMetadataArtifact()`

### getDependencies

    DependencyDescriptor[] getDependencies()

### dependsOn

    boolean dependsOn(VersionMatcher matcher,
                      ModuleDescriptor md)

  Returns true if the module described by this descriptor dependes directly upon the given module descriptor

  Parameters:
    `md` -
  Returns:

### getConfiguration

    Configuration getConfiguration(java.lang.String confName)

  Parameters:
    `confName` -

### getMetadataArtifact

    Artifact getMetadataArtifact()

  Returns the Artifact representing this module descriptor itself.

  Even though the module descriptor is never described as a published artifact of a module in the module descriptor itself, it is often useful to consider it as any other artifact of the module. This method allows to access to the Artifact object representing this module descriptor for this purpose.

    the Artifact representing this module descriptor itself.

### canExclude

    boolean canExclude()

  Returns true if this descriptor contains any exclusion rule

  Parameters:
    `moduleConfs` -
    `artifactId` -
  Returns:

### getAllExcludeRules

    ExcludeRule[] getAllExcludeRules()

  Returns an array of all the exclude rules this module descriptor currently holds. Module Descriptor exclude rules are used to exclude (usually transitive) dependencies for the whole module.

  Returns:
    an array of `ExcludeRule` this module descriptor holds

### getAllDependencyDescriptorMediators

    ModuleRules getAllDependencyDescriptorMediators()

  Returns all the dependency descriptor mediators used by this `ModuleDescriptor`, as an instance of `ModuleRules`.
