CommonTaskOutputChangeDetector

public class CommonTaskOutputChangeDetector

saker.build.task.dependencies.CommonTaskOutputChangeDetector

java.lang.Object

Utility class providing access to common TaskOutputChangeDetector implementations.

TaskContext.reportSelfTaskOutputChangeDetector(TaskOutputChangeDetector)

TaskDependencyFuture.setTaskOutputChangeDetector(TaskOutputChangeDetector)

TaskResultDependencyHandle.setTaskOutputChangeDetector(TaskOutputChangeDetector)

Fields

public static final TaskOutputChangeDetector	ALWAYS Treats the task output as always changed.
public static final TaskOutputChangeDetector	IS_ARRAY Expects the given task output to be an array.
public static final TaskOutputChangeDetector	IS_NOT_ARRAY Expects the given task output to be not an array.
public static final TaskOutputChangeDetector	IS_NULL Expects the task output to be `null`.
public static final TaskOutputChangeDetector	NEVER Treats the task output as never changed.

Methods

public static TaskOutputChangeDetector	equalsTo(Object obj) Gets a task output change detector that expects the task output to equal to the argument.
public static TaskOutputChangeDetector	instanceOf(Class<?> type, boolean expectedinstanceof) Gets a task output change detector that examines if the task output is instance of the given type.
public static TaskOutputChangeDetector	isInstanceOf(Class<?> type) Gets a task output change detector that expects the task output to be an instance of the given type.
public static TaskOutputChangeDetector	isSameClass(Class<?> type) Gets a task output change detector that expects the task to have a given type.
public static TaskOutputChangeDetector	notInstanceOf(Class<?> type) Gets a task output change detector that expects the task output to be not an instance of the given type.

public static final TaskOutputChangeDetector ALWAYS

Treats the task output as always changed.

This is the default TaskOutputChangeDetector for task dependencies. When a task reports this as the output change detector, it will trigger a task change delta if the input task was rerun, and it themself detects that it has changed.

TaskContext.reportSelfTaskOutputChangeDetector(TaskOutputChangeDetector)

TaskFuture.get()

public static final TaskOutputChangeDetector IS_ARRAY

Expects the given task output to be an array.

If the task output is null, a change is detected.

public static final TaskOutputChangeDetector IS_NOT_ARRAY

Expects the given task output to be not an array.

If the task output is null, a change is not detected.

public static final TaskOutputChangeDetector IS_NULL

Expects the task output to be null.

saker.build 0.8.12

public static final TaskOutputChangeDetector NEVER

Treats the task output as never changed.

public static TaskOutputChangeDetector equalsTo(Object obj)

Gets a task output change detector that expects the task output to equal to the argument.

objThe object to check the equality for. May be null.

The output change detector.

public static TaskOutputChangeDetector instanceOf(Class<?> type, boolean expectedinstanceof) throws NullPointerException

Gets a task output change detector that examines if the task output is instance of the given type.

A change is detected if the task output is instance of the given type and it is not expected, or if it is not an instance of the type and it is expected.

typeThe type to check if the task output is instance of.

expectedinstanceofWhether or not to expect the task output to be an instance of the specified type.

The output change detector.

NullPointerExceptionIf the argument is null.

Class.isInstance(Object)

public static TaskOutputChangeDetector isInstanceOf(Class<?> type) throws NullPointerException

Gets a task output change detector that expects the task output to be an instance of the given type.

typeThe type to check if the task output is instance of.

The output change detector.

NullPointerExceptionIf the argument is null.

Class.isInstance(Object)

public static TaskOutputChangeDetector isSameClass(Class<?> type) throws NullPointerException
