protected AbstractArchiveResourceSet getArchiveResourceSet()

getBase

protected final String getBase()

getBaseUrl

protected final String getBaseUrl()

getResource

protected final JarEntry getResource()

getLastModified

public long getLastModified()

Returns:

File.lastModified().

exists

public boolean exists()

Returns:

File.exists().

isVirtual

public boolean isVirtual()

Description copied from interface: WebResource

Indicates if this resource is required for applications to correctly scan the file structure but that does not exist in either the main or any additional WebResourceSet.

isFile

public boolean isFile()

Returns:

File.isFile().

delete

public boolean delete()

Returns:

File.delete().

getName

public String getName()

Returns:

File.getName().

getContentLength

public long getContentLength()

Returns:

File.length().

getCanonicalPath

public String getCanonicalPath()

Returns:

File.getCanonicalPath().

canRead

public boolean canRead()

Returns:

File.canRead().

getCreation

public long getCreation()

Returns:

The time the file was created. If not available, the result of WebResource.getLastModified() will be returned.
