Constructor Detail

ArtifactDescriptor

public ArtifactDescriptor(IArtifactDescriptor base)

Creates a new artifact descriptor with the same key, properties, repository, and processing steps as the provided base descriptor.

Parameters:

base - the descriptor to use as a template for this new descriptor

ArtifactDescriptor

public ArtifactDescriptor(IArtifactKey key)

Returns a new artifact descriptor that uses the provided artifact key

Parameters:

key - The artifact key corresponding to this descriptor

Method Detail

getArtifactKey

public IArtifactKey getArtifactKey()

Description copied from interface: IArtifactDescriptor

Return the key for the artifact described by this descriptor.

Specified by:

getArtifactKey in interface IArtifactDescriptor

Returns:

the key associated with this descriptor

getProperty

public String getProperty(String propertyKey)

Description copied from interface: IArtifactDescriptor

Return the value of the given property in this descriptor null is returned if no such property exists

Specified by:

getProperty in interface IArtifactDescriptor

Parameters:

propertyKey - the property key to look for

Returns:

the value of the given property or null

setProperty

public void setProperty(String key,
                        String value)

addProperties

public void addProperties(Map<String,String> additionalProperties)

getProperties

public Map<String,String> getProperties()

Returns a read-only collection of the properties of the artifact descriptor.

Specified by:

getProperties in interface IArtifactDescriptor

Returns:

the properties of this artifact descriptor.

getProcessingSteps

public IProcessingStepDescriptor[] getProcessingSteps()

Description copied from interface: IArtifactDescriptor

Return the list of processing steps associated with this descriptor. An empty set of steps implies that this descriptor describes a complete copy of the artifact in its native form. If one or more steps are present, they may be performed when the artifact is transferred from the repository that contains it.

Specified by:

getProcessingSteps in interface IArtifactDescriptor

Returns:

the list of processing steps for this descriptor

setProcessingSteps

public void setProcessingSteps(IProcessingStepDescriptor[] value)

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

getRepository

public IArtifactRepository getRepository()

Description copied from interface: IArtifactDescriptor

Return the artifact repository that holds the artifact described by this descriptor. null is returned if this descriptor is not held in a repository.

Specified by:

getRepository in interface IArtifactDescriptor

Returns:

the repository holding this artifact or null if none.

setRepository

public void setRepository(IArtifactRepository value)

toString

public String toString()

Overrides:

toString in class Object

getMember

public Object getMember(String memberName)

Description copied from interface: IMemberProvider

Returns the value for the specified member. Implementers can rely on that the memberName is a string that has been internalized using String.intern().

Specified by:

getMember in interface IMemberProvider

Parameters:

memberName - The name of the member

Returns:

The member value.
