Class DepsAwareTask.DepsSupplier<Impl>

java.lang.Object

com.facebook.buck.core.graph.transformation.executor.DepsAwareTask.DepsSupplier<Impl>

Type Parameters:

Impl - the task type

Enclosing class:

DepsAwareTask<T,Impl extends DepsAwareTask<T,Impl>>

public static class DepsAwareTask.DepsSupplier<Impl>
extends Object

The dependency information of a task.

The prereqSupplier is a supplier that returns a set of tasks necessary to compute depsSupplier. The depsSupplier is a supplier that returns the dependencies.

Method Detail

of

public static <U> DepsAwareTask.DepsSupplier<U> of()

Returns:

a DepsAwareTask.DepsSupplier with no dependencies

of

public static <U> DepsAwareTask.DepsSupplier<U> of(ThrowingSupplier<com.google.common.collect.ImmutableSet<U>,Exception> prereqSupplier,
                                                   ThrowingSupplier<com.google.common.collect.ImmutableSet<U>,Exception> depSupplier)

Returns:

a two staged DepsAwareTask.DepsSupplier, where prereqSupplier is the initial dependency computation, and depSupplier is the dependency computation that occurs after the tasks from the initial dependency computation are complete.
