JavaContext

public JavaContext(@NonNull
                   LintDriver driver,
                   @NonNull
                   Project project,
                   @Nullable
                   Project main,
                   @NonNull
                   java.io.File file)

Constructs a JavaContext for running lint on the given file, with the given scope, in the given project reporting errors to the given client.

Parameters:

driver - the driver running through the checks

project - the project to run lint on which contains the given file

main - the main project if this project is a library project, or null if this is not a library project. The main project is the root project of all library projects, not necessarily the directly including project.

file - the file to be analyzed

Method Detail

getLocation

@NonNull
public Location getLocation(@NonNull
                                    lombok.ast.Node node)

Returns a location for the given node

Parameters:

node - the AST node to get a location for

Returns:

a location for the given node

report

public void report(@NonNull
                   Issue issue,
                   @Nullable
                   Location location,
                   @NonNull
                   java.lang.String message,
                   @Nullable
                   java.lang.Object data)

Description copied from class: Context

Reports an issue. Convenience wrapper around LintClient.report(com.android.tools.lint.detector.api.Context, com.android.tools.lint.detector.api.Issue, com.android.tools.lint.detector.api.Severity, com.android.tools.lint.detector.api.Location, java.lang.String, java.lang.Object)

Overrides:

report in class Context

Parameters:

issue - the issue to report

location - the location of the issue, or null if not known

message - the message for this warning

data - any associated data, or null

report

public void report(@NonNull
                   Issue issue,
                   @Nullable
                   lombok.ast.Node scope,
                   @Nullable
                   Location location,
                   @NonNull
                   java.lang.String message,
                   @Nullable
                   java.lang.Object data)

Reports an issue applicable to a given AST node. The AST node is used as the scope to check for suppress lint annotations.

Parameters:

issue - the issue to report

scope - the AST node scope the error applies to. The lint infrastructure will check whether there are suppress annotations on this node (or its enclosing nodes) and if so suppress the warning without involving the client.

location - the location of the issue, or null if not known

message - the message for this warning

data - any associated data, or null

getSuppressCommentPrefix

@Nullable
protected java.lang.String getSuppressCommentPrefix()

Description copied from class: Context

Returns the comment marker used in Studio to suppress statements for language, if any

Overrides:
