```
- Method Detail
  - 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)
```
  - 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)
```
