Enum Scope

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<Scope>

@Beta
public enum Scope
extends java.lang.Enum<Scope>

The scope of a detector is the set of files a detector must consider when performing its analysis. This can be used to determine when issues are potentially obsolete, whether a detector should re-run on a file save, etc.

NOTE: This is not a public or final API; if you rely on this be prepared to adjust your code for the next tools release.

Enum Constant Detail

RESOURCE_FILE

public static final Scope RESOURCE_FILE

The analysis only considers a single XML resource file at a time.

Issues which are only affected by a single resource file can be checked for incrementally when a file is edited.

ALL_RESOURCE_FILES

public static final Scope ALL_RESOURCE_FILES

The analysis considers all the resource file. This scope must not be used in conjunction with RESOURCE_FILE; an issue scope is either considering just a single resource file or all the resources, not both.

JAVA_FILE

public static final Scope JAVA_FILE

The analysis only considers a single Java source file at a time.

Issues which are only affected by a single Java source file can be checked for incrementally when a Java source file is edited.

ALL_JAVA_FILES

public static final Scope ALL_JAVA_FILES

The analysis considers all the Java source files together.

This flag is mutually exclusive with JAVA_FILE.

CLASS_FILE

public static final Scope CLASS_FILE

The analysis only considers a single Java class file at a time.

Issues which are only affected by a single Java class file can be checked for incrementally when a Java source file is edited and then recompiled.

ALL_CLASS_FILES

public static final Scope ALL_CLASS_FILES

The analysis considers all the Java class files together.

This flag is mutually exclusive with CLASS_FILE.

MANIFEST

public static final Scope MANIFEST

The analysis considers the manifest file

PROGUARD_FILE

public static final Scope PROGUARD_FILE

The analysis considers the Proguard configuration file

JAVA_LIBRARIES

public static final Scope JAVA_LIBRARIES

The analysis considers classes in the libraries for this project. These will be analyzed before the classes themselves.

GRADLE_FILE

public static final Scope GRADLE_FILE

The analysis considers a Gradle build file

OTHER

public static final Scope OTHER

Scope for other files. Issues that specify a custom scope will be called unconditionally. This will call Detector.run(Context)} on the detectors unconditionally.

Field Detail

Method Detail

values

public static Scope[] values()
