Constructor Detail

LayerEntry

public LayerEntry(Path sourceFile,
                  AbsoluteUnixPath extractionPath,
                  FilePermissions permissions,
                  Instant modificationTime)

Instantiates with a source file and the path to place the source file in the container file system.

For example, new LayerEntry(Paths.get("HelloWorld.class"), AbsoluteUnixPath.get("/app/classes/HelloWorld.class")) adds a file HelloWorld.class to the container file system at /app/classes/HelloWorld.class.

For example, new LayerEntry(Paths.get("com"), AbsoluteUnixPath.get("/app/classes/com")) adds a directory to the container file system at /app/classes/com. This does not add the contents of com/.

Note that:

• Entry source files can be either files or directories.
• Adding a directory does not include the contents of the directory. Each file under a directory must be added as a separate LayerEntry.

Parameters:

sourceFile - the source file to add to the layer

extractionPath - the path in the container file system corresponding to the sourceFile

permissions - the file permissions on the container

modificationTime - the file modification time

Method Detail

getModificationTime

public Instant getModificationTime()

Returns the modification time of the file in the entry.

Returns:

the modification time

getSourceFile

public Path getSourceFile()

Gets the source file. The source file may be relative or absolute, so the caller should use getSourceFile().toAbsolutePath().toString() for the serialized form since the serialization could change independently of the path representation.

Returns:

the source file

getExtractionPath

public AbsoluteUnixPath getExtractionPath()

Gets the extraction path.

Returns:

the extraction path

getPermissions

public FilePermissions getPermissions()

Gets the file permissions on the container.

Returns:

the file permissions on the container

equals

public boolean equals(Object other)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
