Class JdevProviderContext

java.lang.Object

oracle.jdeveloper.java.provider.ProviderContext

oracle.jdeveloper.java.provider.JdevProviderContext

All Implemented Interfaces:

ProviderConstants

public class JdevProviderContext
extends ProviderContext

The BaseFileProvider is an abstract starting point for an implementation of the JavaFileProvider interface that relies on a JavaClassLocator instance for locating Java class and source files.

This implementation contains no caching.

Method Detail

getFileType

protected final int getFileType(java.net.URL url)

Use the recognizer to check for source files and class files.

Overrides:

getFileType in class ProviderContext

Returns:

The type of the URL: CLASS_TYPE, SOURCE_TYPE, or UNKNOWN_TYPE.

getSourcePreferences

protected final SourcePreferences getSourcePreferences()

Retrieve preferences options from the coding style manager.

Overrides:

getSourcePreferences in class ProviderContext

Returns:

The SourcePreferences for user-defined preferences, null if none.

createSourceFile

public SourceFile createSourceFile(java.net.URL sourceURL,
                          int j2se)
                            throws java.io.IOException,
                                   java.lang.IllegalArgumentException

Instead of directly interacting with the filesystem, use the Ide's Node model.

Overrides:

createSourceFile in class ProviderContext

Parameters:

sourceURL - The source URL to create a new Java file for.

Returns:

The new source file for the source URL, or null if the file already exists.

Throws:

java.io.IOException - if the new file cannot be created.

java.lang.IllegalArgumentException - if the URL is not recognized as a Java source file.

getSourceFile

public SourceFile getSourceFile(java.net.URL url,

Description copied from class: ProviderContext

Gets a new SourceFile object for the (existing) file at the given URL. If no file exists at the given URL, null is returned.

Overrides:

getSourceFile in class ProviderContext

Parameters:

url - The source URL to create a new Java file for.

Returns:

The new source file for the source URL, or null if the file did not exist.

writeSourceFile

public boolean writeSourceFile(SourceFile file)

Description copied from class: ProviderContext

Called when SourceTransaction.commit() is called for the given file.

Overrides:

writeSourceFile in class ProviderContext

Returns:

False if an error occurred.

getTextBuffer

protected TextBuffer getTextBuffer(java.net.URL url)

Fetch the TextBuffer for the given URL.

Overrides:

getTextBuffer in class ProviderContext

Returns:

A newly created TextBuffer if successful, null otherwise.

startTracking

protected void startTracking(java.net.URL url)

Utility routine to start tracking the Node represented by the URL.

Overrides:

stopTracking

protected void stopTracking(java.net.URL url)

Utility routine to stop tracking the Node represented by the URL.

clearTracking

public void clearTracking()

Utility routine to stop tracking all Nodes.

Overrides:

clearTracking in class ProviderContext
