Artifact (Google Web Toolkit Javadoc)

java.lang.Object
- com.google.gwt.core.ext.linker.Artifact<C>

Type Parameters:
C - The type of Artifact interface that the Artifact can be compared to.

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<Artifact<?>>

Direct Known Subclasses:

CompilationMetricsArtifact, CompilationResult, EmittedArtifact, ModuleMetricsArtifact, PrecompilationMetricsArtifact, RpcDataArtifact, RpcLogArtifact, RpcPolicyFileArtifact, ScriptReference, StylesheetReference, SymbolMapsLinker.ScriptFragmentEditsArtifact
```
public abstract class Artifact<C extends Artifact<C>>
extends java.lang.Object
implements java.lang.Comparable<Artifact<?>>, java.io.Serializable
```
A base type for all artifacts relating to the link process. In order to ensure stable output between runs of the compiler, Artifact types must implement a stable comparison between instances of a relevant base type (the exact comparison order is irrelevant).

Methods
Modifier and Type	Method and Description
`int`	`compareTo(Artifact<?> o)`
`protected abstract int`	`compareToComparableArtifact(C o)` Performs comparison with an artifact of a compatible base type.
`boolean`	`equals(java.lang.Object obj)` Delegates to `compareTo(Artifact)`.
`protected abstract java.lang.Class<C>`	`getComparableArtifactType()` Returns the base type to use for comparisons between Artifacts.
`java.lang.Class<? extends Linker>`	`getLinker()` Returns the Linker that created the Artifact.
`abstract int`	`hashCode()` The class which is returned from `getComparableArtifactType()` must declare a final implementation which returns the same hash code for objects for which `compareToComparableArtifact(Artifact)` returns 0.
`boolean`	`isTransferableFromShards()` Returns whether the `Transferable` annotation is present on this class.
`java.lang.String`	`toString()`

```
protected Artifact(java.lang.Class<? extends Linker> linker)
```
    Constructor.
    
    Parameters:
    linker - the type of Linker that instantiated the Artifact.
- Method Detail
  - compareTo
```
public final int compareTo(Artifact<?> o)
```
    Specified by:
    
    compareTo in interface java.lang.Comparable<Artifact<?>>
  - equals
```
public final boolean equals(java.lang.Object obj)
```
    Delegates to compareTo(Artifact).
    
    Overrides:
    
    equals in class java.lang.Object
  - getLinker
```
public final java.lang.Class<? extends Linker> getLinker()
```
    Returns the Linker that created the Artifact.
  - hashCode
```
public abstract int hashCode()
```
    The class which is returned from getComparableArtifactType() must declare a final implementation which returns the same hash code for objects for which compareToComparableArtifact(Artifact) returns 0.
    
    Overrides:
    
    hashCode in class java.lang.Object
  - isTransferableFromShards
```
public final boolean isTransferableFromShards()
```
    Returns whether the Transferable annotation is present on this class. See Transferable for the implications.
  - toString
```
public java.lang.String toString()
```
    Overrides:
    
    toString in class java.lang.Object
  - compareToComparableArtifact
```
protected abstract int compareToComparableArtifact(C o)
```
    Performs comparison with an artifact of a compatible base type. Objects which compare to 0 are assumed equal, and must return the same hashCode().
  - getComparableArtifactType
```
protected abstract java.lang.Class<C> getComparableArtifactType()
```
    Returns the base type to use for comparisons between Artifacts. All concrete implementations of this methods must be final.
