Constructor Detail

Fingerprint

public Fingerprint(@CheckForNull
                   Run build,
                   @Nonnull
                   String fileName,
                   @Nonnull
                   byte[] md5sum)
            throws IOException

Throws:

IOException

Method Detail

getOriginal

@Exported
 @CheckForNull
public Fingerprint.BuildPtr getOriginal()

The first build in which this file showed up, if the file looked like it's created there.

This is considered as the "source" of this file, or the owner, in the sense that this project "owns" this file.

Returns:

null if the file is apparently created outside Hudson or if the current user has no permission to discover the job.

getDisplayName

@Nonnull
public String getDisplayName()

Specified by:

getDisplayName in interface ModelObject

getFileName

@Exported
 @Nonnull
public String getFileName()

The file name (like "foo.jar" without path).

getHashString

@Exported(name="hash")
 @Nonnull
public String getHashString()

Gets the MD5 hash string.

getTimestamp

@Exported
 @Nonnull
public Date getTimestamp()

Gets the timestamp when this record is created.

getTimestampString

@Nonnull
public String getTimestampString()

Gets the string that says how long since this build has scheduled.

Returns:

string like "3 minutes" "1 day" etc.

getRangeSet

@Nonnull
public Fingerprint.RangeSet getRangeSet(String jobFullName)

Gets the build range set for the given job name.

These builds of this job has used this file.

Returns:

may be empty but not null.

getRangeSet

public Fingerprint.RangeSet getRangeSet(Job job)

getJobs

@Nonnull
public List<String> getJobs()

Gets the sorted list of job names where this jar is used.

getUsages

@Nonnull
public Hashtable<String,Fingerprint.RangeSet> getUsages()

_getUsages

@Exported(name="usage")
 @Nonnull
public List<Fingerprint.RangeItem> _getUsages()

add

@Deprecated
public void add(@Nonnull
                            AbstractBuild b)
                     throws IOException

Deprecated. Use addFor(hudson.model.Run)

Throws:

IOException

addFor

public void addFor(@Nonnull
                   Run b)
            throws IOException

Adds a usage reference to the build.

Parameters:

b - Run to be referenced in usages

Throws:

IOException

Since:

1.577

add

public void add(@Nonnull
                String jobFullName,
                int n)
         throws IOException

Records that a build of a job has used this file.

Throws:

IOException

isAlive

public boolean isAlive()

Returns true if any of the builds recorded in this fingerprint is still retained.

This is used to find out old fingerprint records that can be removed without losing too much information.

trim

public boolean trim()
             throws IOException

Trim off references to non-existent builds and jobs, thereby making the fingerprint smaller.

Returns:

true if this record was modified.

Throws:

IOException - Save failure

getFacets

@Nonnull
public Collection<FingerprintFacet> getFacets()

Gets the associated FingerprintFacets.

This method always return a non-empty collection, which is a synthetic collection. It contains persisted FingerprintFacets (those that are added explicitly, like fingerprint.getFacets().add(x)), as well those that are transient.

Mutation to this collection will manipulate persisted set of FingerprintFacets, and therefore regardless of what you do, this collection will always contain a set of FingerprintFacets that are added by TransientFingerprintFacetFactorys.

Since:

1.421

getSortedFacets

@Nonnull
public Collection<FingerprintFacet> getSortedFacets()

Sorts FingerprintFacets by their timestamps.

Returns:

Sorted list of FingerprintFacets

getFacet

@CheckForNull
public <T extends FingerprintFacet> T getFacet(Class<T> type)

Finds a facet of the specific type (including subtypes.)

Type Parameters:

T - Class of the FingerprintFacet

Returns:

First matching facet of the specified class

Since:

1.556

getActions

@Nonnull
public List<Action> getActions()

Returns the actions contributed from getFacets()

save

public void save()
          throws IOException

Save the settings to a file.

Specified by:

save in interface Saveable

Throws:

IOException - Save error

rename

public void rename(String oldName,
                   String newName)
            throws IOException

Update references to a renamed job in the fingerprint

Throws:

IOException

getApi

public Api getApi()

toString

public String toString()

Overrides:

toString in class Object
