Method Summary

SourceFile	createSourceFile(java.net.URL sourceURL) Creates a new SourceFile for the given Java source URL (*.java).
JavaFile	getFile(java.net.URL url) Fetch the JavaFile for the given URL.
SourceFile	getSourceFile(TextBuffer textBuffer) Creates a new SourceFile from the input TextBuffer but NOT tied any particular Java source URL.

Method Detail

getFile

JavaFile getFile(java.net.URL url)

Fetch the JavaFile for the given URL. The URL can be either a Java class file (*.class) or a Java source file (*.java). The classes contained in that file represented by the URL can be fetched from the JavaFile.

Parameters:

url - the URL to get the Java file for

Returns:

the Java file for that URL.

getSourceFile

SourceFile getSourceFile(java.net.URL sourceURL)

Fetch the SourceFile for the given Java source URL (*.java). The classes contained in the file represented by the URL can be fetched from the source file. If the URL does not represent a valid Java source file, or if the URL points to a non-existing file, then null will be returned.

Parameters:

sourceURL - the source URL to get the Java file for

Returns:

the source file for the source URL

createSourceFile

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

Creates a new SourceFile for the given Java source URL (*.java). This will create a new empty file for the given URL, and return a SourceFile instance for it. If the file already exists on disk, then this will return null.

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 could not be created because it 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

SourceFile getSourceFile(TextBuffer textBuffer)

Creates a new SourceFile from the input TextBuffer but NOT tied any particular Java source URL. In particular, that means that the contents of this SourceFile are NOT fetchable and therefore this SourceFile cannot be referenced by any other.

Returns:

a newly created SourceFile based on the input TextBuffer.
