public static UnconfiguredTargetNodeToUnconfiguredTargetNodeWithDepsComputation of(UnconfiguredTargetNodeToTargetNodeFactory unconfiguredTargetNodeToTargetNodeFactory,
                                                                                   Cell cell)

Create new instance of UnconfiguredTargetNodeToUnconfiguredTargetNodeWithDepsComputation

Parameters:

unconfiguredTargetNodeToTargetNodeFactory - An actual factory that will create TargetNode from UnconfiguredTargetNode in order to resolve deps

cell - A Cell object that contains targets used in this transformation, it is mostly used to resolve paths to absolute paths

getIdentifier

public ComputationIdentifier<UnconfiguredTargetNodeWithDeps> getIdentifier()

Specified by:

getIdentifier in interface GraphComputation<UnconfiguredTargetNodeToUnconfiguredTargetNodeWithDepsKey,UnconfiguredTargetNodeWithDeps>

Returns:

the identifier of the key for this transformation. This should match ComputeKey.getIdentifier()

transform

public UnconfiguredTargetNodeWithDeps transform(UnconfiguredTargetNodeToUnconfiguredTargetNodeWithDepsKey key,
                                                ComputationEnvironment env)

Description copied from interface: GraphComputation

Perform a transformation identified by key Key into a final type Result. This transformation should be performed synchronously.

Specified by:

transform in interface GraphComputation<UnconfiguredTargetNodeToUnconfiguredTargetNodeWithDepsKey,UnconfiguredTargetNodeWithDeps>

Parameters:

key - The Key of the requested result

env - The execution environment containing results of keys from GraphComputation.discoverDeps(ComputeKey, ComputationEnvironment) and GraphComputation.discoverPreliminaryDeps(ComputeKey)

Returns:

The result of the transformation

discoverDeps

public com.google.common.collect.ImmutableSet<? extends ComputeKey<? extends ComputeResult>> discoverDeps(UnconfiguredTargetNodeToUnconfiguredTargetNodeWithDepsKey key,
                                                                                                          ComputationEnvironment env)

Description copied from interface: GraphComputation

Compute dependent keys required to compute given key, and a set of dependencies as listed by GraphComputation.discoverPreliminaryDeps(ComputeKey). The results of those computations will be available in GraphComputation.transform(ComputeKey, ComputationEnvironment) as a part of ComputationEnvironment

Specified by:

discoverDeps in interface GraphComputation<UnconfiguredTargetNodeToUnconfiguredTargetNodeWithDepsKey,UnconfiguredTargetNodeWithDeps>

Parameters:

key - the current key to transform

env - The execution environment containing results of keys from GraphComputation.discoverPreliminaryDeps(ComputeKey)

Returns:

a set of keys that the transformation of the current key depends on

discoverPreliminaryDeps

public com.google.common.collect.ImmutableSet<? extends ComputeKey<? extends ComputeResult>> discoverPreliminaryDeps(UnconfiguredTargetNodeToUnconfiguredTargetNodeWithDepsKey key)

Description copied from interface: GraphComputation

Compute dependent keys required to compute given the current key. The results of those computations will be available in GraphComputation.discoverDeps(ComputeKey, ComputationEnvironment) as a part of ComputationEnvironment, and GraphComputation.transform(ComputeKey, ComputationEnvironment)

Specified by:

discoverPreliminaryDeps in interface GraphComputation<UnconfiguredTargetNodeToUnconfiguredTargetNodeWithDepsKey,UnconfiguredTargetNodeWithDeps>

Parameters:

key - the current key to transform

Returns:

a set of keys that the GraphComputation.discoverDeps(ComputeKey, ComputationEnvironment) and GraphComputation.transform(ComputeKey, ComputationEnvironment) of the current key depends on
