Constructor Detail

DelegatingArtifact

protected DelegatingArtifact(Artifact delegate)
Creates a new artifact instance that delegates to the specified artifact.

Parameters:
delegate - The artifact to delegate to, must not be null.
Method Detail

newInstance

protected abstract DelegatingArtifact newInstance(Artifact delegate)
Creates a new artifact instance that delegates to the specified artifact. Subclasses should use this hook to instantiate themselves, taking along any data from the current instance that was added.

Parameters:
delegate - The artifact to delegate to, must not be null.
Returns:
The new delegating artifact, never null.

getGroupId

public String getGroupId()
Description copied from interface: Artifact
Gets the group identifier of this artifact, for example "org.apache.maven".

Returns:
The group identifier, never null.

getArtifactId

public String getArtifactId()
Description copied from interface: Artifact
Gets the artifact identifier of this artifact, for example "maven-model".

Returns:
The artifact identifier, never null.

getVersion

public String getVersion()
Description copied from interface: Artifact
Gets the version of this artifact, for example "1.0-20100529-1213". Note that in case of meta versions like "1.0-SNAPSHOT", the artifact's version depends on the state of the artifact. Artifacts that have been resolved or deployed will have the meta version expanded.

Returns:
The version, never null.

setVersion

public Artifact setVersion(String version)
Description copied from interface: Artifact
Sets the version of this artifact.

Specified by:
setVersion in interface Artifact
Overrides:
setVersion in class AbstractArtifact
Parameters:
version - The version of this artifact, may be null or empty.
Returns:
The new artifact, never null.

getBaseVersion

public String getBaseVersion()
Description copied from interface: Artifact
Gets the base version of this artifact, for example "1.0-SNAPSHOT". In contrast to the Artifact.getVersion(), the base version will always refer to the unresolved meta version.

Returns:
The base version, never null.

isSnapshot

public boolean isSnapshot()
Description copied from interface: Artifact
Determines whether this artifact uses a snapshot version.

Returns:
true if the artifact is a snapshot, false otherwise.

getClassifier

public String getClassifier()
Description copied from interface: Artifact
Gets the classifier of this artifact, for example "sources".

Returns:
The classifier or an empty string if none, never null.

getExtension

public String getExtension()
Description copied from interface: Artifact
Gets the (file) extension of this artifact, for example "jar".

Returns:
The file extension, never null.

getFile

public File getFile()
Description copied from interface: Artifact
Gets the file of this artifact. Note that only resolved artifacts have a file associated with them.

Returns:
The file or null if the artifact isn't resolved.

setFile

public Artifact setFile(File file)
Description copied from interface: Artifact
Sets the file of the artifact.

Specified by:
setFile in interface Artifact
Overrides:
setFile in class AbstractArtifact
Parameters:
file - The file of the artifact, may be null
Returns:
The new artifact, never null.

getProperty

public String getProperty(String key,
                          String defaultValue)
Description copied from interface: Artifact
Gets the specified property.

Parameters:
key - The name of the property, must not be null.
defaultValue - The default value to return in case the property is not set, may be null.

getProperties

public Map<String,String> getProperties()
Description copied from interface: Artifact
Gets the properties of this artifact. While the exact set of available properties is undefined, the following properties are considered to be common:
type
A high-level characterization of the artifact, e.g. "maven-plugin" or "test-jar".
language
The programming language this artifact is relevant for, e.g. "java" or "none".
includesDependencies
A boolean flag indicating whether the artifact presents some kind of bundle that physically includes its dependencies, e.g. a fat WAR.
constitutesBuildPath
A boolean flag indicating whether the artifact is meant to be used for the compile/runtime/test build path of a consumer project.
localPath
The (expected) path to the artifact on the local filesystem. An artifact which has this property set is assumed to be not present in any regular repository and likewise has no artifact descriptor.

Returns:
The (read-only) properties, never null.

setProperties

public Artifact setProperties(Map<String,String> properties)
Description copied from interface: Artifact
Sets the properties for the artifact.

Specified by:
setProperties in interface Artifact
Overrides:
setProperties in class AbstractArtifact
Parameters:
properties - The properties for the artifact, may be null.
Returns:
The new artifact, never null.

equals

public boolean equals(Object obj)
Overrides:
equals in class AbstractArtifact

hashCode

public int hashCode()
Overrides:
hashCode in class AbstractArtifact

toString

public String toString()
Overrides:
toString in class AbstractArtifact
