Method Detail

initialize

public void initialize(java.lang.String versionId,
                       java.lang.String versionName,
                       Resource res)
                throws VersionMutationException

Description copied from interface: Version

Initialize the core properties of the version.

Specified by:

initialize in interface Version

Throws:

VersionMutationException

initialize

public void initialize(java.lang.String versionId,
                       java.lang.String versionName,
                       java.util.Set previousVersions,
                       Resource res)
                throws VersionMutationException

Specified by:

initialize in interface Version

Throws:

VersionMutationException

setAsFixed

public void setAsFixed()

Description copied from interface: Version

Sets the version as "fixed", meaning that it cannot be mutated further. This method also adds the version to the resource. While versions know what resource they are a version of, until they are committed to the repository, the resource doesn't know about the version.

Specified by:

setAsFixed in interface Version

isFixed

public boolean isFixed()

Specified by:

isFixed in interface Version

checkIsNotFixed

public void checkIsNotFixed()
                     throws VersionMutationException

Specified by:

checkIsNotFixed in interface Version

Throws:

VersionMutationException

addDependency

public void addDependency(DependencyLink dependency)
                   throws VersionMutationException

Specified by:

addDependency in interface Version

Throws:

VersionMutationException

getDependencies

public DependencyMap getDependencies()

Description copied from interface: Version

Returns the set of dependency

Specified by:

getDependencies in interface Version

Returns:

getDependenciesByType

public DependencyMap getDependenciesByType(java.lang.String typeName)

Description copied from interface: Version

Returns a collection of dependencies of the specififed type, if any.

Specified by:

getDependenciesByType in interface Version

Parameters:

typeName - The fully-qualified type name for the dependency (the Java class name for the dependency type.

Returns:

The set of dependencies of the specified type. May be empty.

getResource

public Resource getResource()

Specified by:

getResource in interface Version

dependsOn

public boolean dependsOn(Resource resource)

Description copied from interface: Version

Returns true if the version has one or more dependency relationships of any type to the specified resource.

Specified by:

dependsOn in interface Version

Returns:

Returns true if there are any dependencies.

dependsOn

public boolean dependsOn(Resource resource,
                         java.lang.String dependencyTypeName)

Description copied from interface: Version

Returns true if the version has one or more dependency relationships to the specified resource.

Specified by:

dependsOn in interface Version

dependencyTypeName - The name of the dependency type to check. If null, checks all dependency types.

Returns:

Returns true if there are any dependencies of the specified type.

getPrevious

public VersionMap getPrevious()

Description copied from interface: Version

Gets the previous versions for this version.

Specified by:

getPrevious in interface Version

Returns:

VersionMap of previous versions, if any.

getNext

public VersionMap getNext()

Description copied from interface: Version

Gets the previous versions for this version.

Specified by:

getNext in interface Version

Returns:

VersionMapImpl of next versions, if any.

setPrevious

public void setPrevious(VersionMap previousVersions)
                 throws VersionMutationException

Description copied from interface: Version

Sets the previous versions for this version. Cannot be called once the version is fixed.

Specified by:

setPrevious in interface Version

Parameters:

previousVersions - Versionmap of previous versions.

Throws:

VersionMutationException

addPreviousVersion

public void addPreviousVersion(Version effectiveVer)

Description copied from interface: Version

Adds a version as being a next version of this version. Also adds the specified version as a previous version of this version. This can be done at any time, whether or not the versions involved are fixed.

Specified by:

addPreviousVersion in interface Version

addNextVersion

public void addNextVersion(Version ver)

Description copied from interface: Version

Adds a version as being a previous version of this version. Note that we can't add this version as a next version of the specified previous version at this time unless this version is fixed. That is, fixed versions cannot point to versions in mutable snapshots, at least as far as the invariant part of the repository is concerned. This normally happens when a version is created on a snapshot, although it could be done at other times.

Specified by:

addNextVersion in interface Version

collectTargetVersions

public void collectTargetVersions(VersionMap members,
                                  Snapshot onSnapshot,
                                  java.lang.String dependencyTypeName)

Description copied from interface: Version

Gets all the versions on which this version is dependent for a given dependency class.

Specified by:

collectTargetVersions in interface Version

Parameters:

members - The version map to which the target versions are added

onSnapshot - The snapshot on which to resolve the dependencies

dependencyTypeName - The class name of the dependency type
