Class ParametersAction

java.lang.Object

hudson.model.ParametersAction

All Implemented Interfaces:

Action, EnvironmentContributingAction, LabelAssignmentAction, ModelObject, Queue.QueueAction, Iterable<ParameterValue>, RunAction2

@ExportedBean
public class ParametersAction
extends Object
implements RunAction2, Iterable<ParameterValue>, Queue.QueueAction, EnvironmentContributingAction, LabelAssignmentAction

Records the parameter values used for a build.

This object is associated with the build record so that we remember what parameters were used for what build. It is also attached to the queue item to remember parameter that were specified when scheduling.

Field Detail

KEEP_UNDEFINED_PARAMETERS_SYSTEM_PROPERTY_NAME

@Restricted(value=org.kohsuke.accmod.restrictions.NoExternalUse.class)
public static final String KEEP_UNDEFINED_PARAMETERS_SYSTEM_PROPERTY_NAME

Three state variable (null, false, true). If explicitly set to true, it will keep all variable, explicitly set to false it will drop all of them (except if they are marked safe). If null, and they are not safe, it will log a warning in logs to the user to let him choose the behavior

Since:

2.3

SAFE_PARAMETERS_SYSTEM_PROPERTY_NAME

@Restricted(value=org.kohsuke.accmod.restrictions.NoExternalUse.class)
public static final String SAFE_PARAMETERS_SYSTEM_PROPERTY_NAME

Constructor Detail

ParametersAction

public ParametersAction(@Nonnull
                        List<ParameterValue> parameters)

ParametersAction

public ParametersAction(List<ParameterValue> parameters,
                        Collection<String> additionalSafeParameters)

Constructs a new action with additional safe parameters. The additional safe parameters should be only those considered safe to override the environment and what is declared in the project config in addition to those specified by the user in SAFE_PARAMETERS_SYSTEM_PROPERTY_NAME. See SECURITY-170

Parameters:

parameters - the parameters

additionalSafeParameters - additional safe parameters

Since:

1.651.2, 2.3

ParametersAction

public ParametersAction(ParameterValue... parameters)

Method Detail

createBuildWrappers

public void createBuildWrappers(AbstractBuild<?,?> build,
                                Collection<? super BuildWrapper> result)

buildEnvironment

public void buildEnvironment(Run<?,?> run,
                             EnvVars env)

Description copied from interface: EnvironmentContributingAction

Called by Run to allow plugins to contribute environment variables.

Specified by:

buildEnvironment in interface EnvironmentContributingAction

Parameters:

run - The calling build. Never null.

env - Environment variables should be added to this map.

substitute

public String substitute(AbstractBuild<?,?> build,
                         String text)

Performs a variable substitution to the given text and return it.

createVariableResolver

public VariableResolver<String> createVariableResolver(AbstractBuild<?,?> build)

Creates an VariableResolver that aggregates all the parameters.

If you are a BuildStep, most likely you should call AbstractBuild.getBuildVariableResolver().

iterator

public Iterator<ParameterValue> iterator()

Specified by:

iterator in interface Iterable<ParameterValue>

getParameters

@Exported(visibility=2)
public List<ParameterValue> getParameters()

getParameter

public ParameterValue getParameter(String name)

getAssignedLabel

public Label getAssignedLabel(SubTask task)

Description copied from interface: LabelAssignmentAction

Reassigns where the task gets run.

Specified by:

getAssignedLabel in interface LabelAssignmentAction

Parameters:

task - Never null.

Returns:

null to let other LabelAssignmentActions take control, eventually to SubTask#getAssignedLabel(). If non-null value is returned, that label will be authoritative.

getDisplayName

public String getDisplayName()

Description copied from interface: Action

Gets the string to be displayed. The convention is to capitalize the first letter of each word, such as "Test Result".

Specified by:

getDisplayName in interface Action

Specified by:

getDisplayName in interface ModelObject

Returns:

Can be null in case the action is hidden.

getIconFileName

public String getIconFileName()

Description copied from interface: Action

Gets the file name of the icon.

Specified by:

getIconFileName in interface Action

Returns:

If just a file name (like "abc.gif") is returned, it will be interpreted as a file name inside /images/24x24. This is useful for using one of the stock images.

If an absolute file name that starts from '/' is returned (like "/plugin/foo/abc.gif'), then it will be interpreted as a path from the context root of Jenkins. This is useful to pick up image files from a plugin.

Finally, return null to hide it from the task list. This is normally not very useful, but this can be used for actions that only contribute floatBox.jelly and no task list item. The other case where this is useful is to avoid showing links that require a privilege when the user is anonymous.

See Also:

Functions.isAnonymous(), Functions.getIconFilePath(Action)

getUrlName

public String getUrlName()

Description copied from interface: Action

Gets the URL path name.

For example, if this method returns "xyz", and if the parent object (that this action is associated with) is bound to /foo/bar/zot, then this action object will be exposed to /foo/bar/zot/xyz.

This method should return a string that's unique among other Actions.

The returned string can be an absolute URL, like "http://www.sun.com/", which is useful for directly connecting to external systems.

If the returned string starts with '/', like '/foo', then it's assumed to be relative to the context path of the Jenkins webapp.

Specified by:

getUrlName in interface Action

Returns:

null if this action object doesn't need to be bound to web (when you do that, be sure to also return null from Action.getIconFileName().

See Also:

Functions.getActionUrl(String, Action)

shouldSchedule

public boolean shouldSchedule(List<Action> actions)

Allow an other build of the same project to be scheduled, if it has other parameters.

Specified by:

shouldSchedule in interface Queue.QueueAction

createUpdated

@Nonnull
public ParametersAction createUpdated(Collection<? extends ParameterValue> overrides)

Creates a new ParametersAction that contains all the parameters in this action with the overrides / new values given as parameters.

Returns:

New ParametersAction. The result may contain null ParameterValues

merge

@Nonnull
public ParametersAction merge(@CheckForNull
                                       ParametersAction overrides)

onAttached

public void onAttached(Run<?,?> r)

Description copied from interface: RunAction2

Called when this action is added to a build.

Specified by:

onAttached in interface RunAction2

onLoad

public void onLoad(Run<?,?> r)

Description copied from interface: RunAction2

Called after a build is loaded to which this action was previously attached.

Specified by:

onLoad in interface RunAction2

getAllParameters

public List<ParameterValue> getAllParameters()

Returns all parameters. Be careful in how you process them. It will return parameters even not being defined as ParametersDefinitionProperty in the job, so any external caller could inject any parameter (using any key) here. Treat it as untrusted data.

Returns:

all parameters defined here.

Since:

1.651.2, 2.3
