TargetNode (Buck)

All Superinterfaces:

Comparable<TargetNode<?>>, ComputeResult, DependencyStack.ProvidesElement, HasBuildTarget, ObeysVisibility

All Known Implementing Classes:

TargetNodeImpl
```
public interface TargetNode<T extends ConstructorArg>
extends Comparable<TargetNode<?>>, ObeysVisibility, HasBuildTarget, ComputeResult, DependencyStack.ProvidesElement
```
A TargetNode represents a node in the target graph which is created by the Parser as a result of parsing BUCK files in a project. It is responsible for processing the raw (python) inputs of a build rule, and gathering any build targets and paths referenced from those inputs.

```
  - getExtraDeps
```
com.google.common.collect.ImmutableSortedSet<BuildTarget> getExtraDeps()
```
  - getTargetGraphOnlyDeps
```
com.google.common.collect.ImmutableSortedSet<BuildTarget> getTargetGraphOnlyDeps()
```
    BuildTargetPaths which, when changed, may change the BuildRules produced by this TargetNode, but whose steps don't need executing in order to build this TargetNode's BuildRules.
    A TargetNode may require metadata from other targets in order to be constructed, but may not actually require those targets' build output. For example, some targets may execute queries against the TargetGraph (e.g. detecting the names of rules of a certain type) but don't use the output of those detected rules.
  - getConfigurationDeps
```
com.google.common.collect.ImmutableSortedSet<BuildTarget> getConfigurationDeps()
```
    Provides a set of configuration targets that were used during the construction of this node.
    For example, this set would include configuration targets specified as keys in select statements.
  - getVisibilityPatterns
```
com.google.common.collect.ImmutableSet<VisibilityPattern> getVisibilityPatterns()
```
  - getWithinViewPatterns
```
com.google.common.collect.ImmutableSet<VisibilityPattern> getWithinViewPatterns()
```
  - getSelectedVersions
```
Optional<com.google.common.collect.ImmutableMap<BuildTarget,Version>> getSelectedVersions()
```
  - getBuildDeps
```
Set<BuildTarget> getBuildDeps()
```
    Returns:
    
    all targets which must be built before this one can be.
  - getParseDeps
```
Set<BuildTarget> getParseDeps()
```
    Returns:
    
    all targets which must be present in the TargetGraph before this one can be transformed into a BuildRule.
  - getTotalDeps
```
Set<BuildTarget> getTotalDeps()
```
    Dependencies that include build targets as well as configuration targets that this node depends on.
  - isVisibleTo
```
boolean isVisibleTo(TargetNode<?> viewer)
```

  - getRuleType
```
RuleType getRuleType()
```
  - copyWithFlavors
```
TargetNode<T> copyWithFlavors(com.google.common.collect.ImmutableSet<Flavor> flavors)
```
    This method copies this target node with applying logic in ImplicitDepsInferringDescription that may give different results for deps based on flavors.
    Note that this method strips away selected versions, and may be buggy because of it.
  - copyWithFlavors

```
  - withFlavors
```
TargetNode<T> withFlavors(com.google.common.collect.ImmutableSet<Flavor> flavors)
