Method Details

getFileBase

protected final File getFileBase()

setReadOnly

public void setReadOnly(boolean readOnly)

Description copied from interface: WebResourceSet

Configures whether or not this set of resources is read-only.

Parameters:

readOnly - true if this set of resources should be configured to be read-only

isReadOnly

public boolean isReadOnly()

Description copied from interface: WebResourceSet

Obtains the current value of the read-only setting for this set of resources.

Returns:

true if this set of resources is configured to be read-only, otherwise false

file

protected final File file(String name,
 boolean mustExist)

logIgnoredSymlink

protected void logIgnoredSymlink(String contextPath,
 String absPath,
 String canPath)

getBaseUrl

public URL getBaseUrl()

Description copied from interface: WebResourceSet

Obtain the base URL for this set of resources. One of the uses of this is to grant read permissions to the resources when running under a security manager.

Returns:

The base URL for this set of resources

gc

public void gc()

Implementations may cache some information to improve performance. This method triggers the clean-up of those resources.

This is a NO-OP by default for File based resource sets.

initInternal

protected void initInternal()
                     throws LifecycleException

Description copied from class: LifecycleBase

Sub-classes implement this method to perform any instance initialisation required.

Specified by:

initInternal in class LifecycleBase

Throws:

LifecycleException - If the initialisation fails

checkType

protected abstract void checkType(File file)
