Modifier and Type	Method and Description
`static int`	`countActive()`
`static <T> Callable<T>`	`decorate(Callable<T> callable)` Decorates a callable with `ContextPropagatingCallable` making it possible to access the `Context` from within the decorated callable.
`static void`	`destroy()` Perform context clean-up.
`static Context`	`get()`

`static boolean`	`isContextSet()`
`static void`	`set(Context context)` Set a context with default configuration to current thread.
`static void`	`set(Context context, WroConfiguration config)` Associate a context with the CURRENT request cycle.
`void`	`setAggregatedFolderPath(String aggregatedFolderPath)`
`void`	`setConfig(WroConfiguration config)` DO NOT CALL THIS METHOD UNLESS YOU ARE SURE WHAT YOU ARE DOING.
`static void`	`setCorrelationId(String correlationId)` Set the correlationId to the current thread.
`static Context`	`standaloneContext()` A context useful for running in non web context (standalone applications).
`String`	`toString()`

`static void`	`unsetCorrelationId()` Remove the correlationId from the current thread.

- Method Detail
  - getConfig
```
public WroConfiguration getConfig()
```
    Specified by:
    
    getConfig in interface ReadOnlyContext
    
    Returns:
    WroConfiguration singleton instance.
  - setConfig
```
public void setConfig(WroConfiguration config)
```
    DO NOT CALL THIS METHOD UNLESS YOU ARE SURE WHAT YOU ARE DOING.
    sets the WroConfiguration singleton instance.
  - webContext
```
public static Context webContext(javax.servlet.http.HttpServletRequest request,
                 javax.servlet.http.HttpServletResponse response,
                 javax.servlet.FilterConfig filterConfig)
```
    A context useful for running in web context (inside a servlet container).
  - standaloneContext
```
public static Context standaloneContext()
```
    A context useful for running in non web context (standalone applications).
  - get
```
public static Context get()
```
    Returns:
    Context associated with CURRENT request cycle.
  - isContextSet
```
public static boolean isContextSet()
```
    Returns:
    true if the call is done during wro4j request cycle. In other words, if the context is set.
  - set
```
public static void set(Context context)
```
    Set a context with default configuration to current thread.
  - set
```
public static void set(Context context,
       WroConfiguration config)
```
    Associate a context with the CURRENT request cycle.
    
    Parameters:
    context - Context to set.
  - unset
```
public static void unset()
```
    Remove context from the local thread.
  - destroy
```
public static void destroy()
```
    Perform context clean-up.
  - setCorrelationId
```
public static void setCorrelationId(String correlationId)
```
    Set the correlationId to the current thread.
  - unsetCorrelationId
```
public static void unsetCorrelationId()
```
    Remove the correlationId from the current thread. This operation will not remove the Context associated with the correlationId. In order to remove context, call unset().
    Unsetting correlationId is useful when you create child threads which needs to access the correlationId from the parent thread. This simulates the InheritableThreadLocal functionality.
  - getCorrelationId
```
public static String getCorrelationId()
```
    Returns:
    the correlationId associated with this thread.
  - decorate
```
public static <T> Callable<T> decorate(Callable<T> callable)
```
    Decorates a callable with ContextPropagatingCallable making it possible to access the Context from within the decorated callable.
    
    Parameters:
    callable - the Callable to decorate.
    
    Returns:
    the decorated callable.
  - countActive
```
public static int countActive()
```
    Returns:
    number of Context objects which were created but not yet destroyed. This is useful to detect leaks (mostly for unit testing).
  - getRequest
```
public javax.servlet.http.HttpServletRequest getRequest()
```
    Specified by:
    
    getRequest in interface ReadOnlyContext
    
    Returns:
    the request
  - getResponse
```
public javax.servlet.http.HttpServletResponse getResponse()
```
    Specified by:
    
    getResponse in interface ReadOnlyContext
    
    Returns:
    the response
  - getServletContext
```
public javax.servlet.ServletContext getServletContext()
```
    Specified by:
    
    getServletContext in interface ReadOnlyContext
    
    Returns:
    the servletContext
  - getFilterConfig
```
public javax.servlet.FilterConfig getFilterConfig()
```
    Specified by:
    
    getFilterConfig in interface ReadOnlyContext
    
    Returns:
    the filterConfig
  - getAggregatedFolderPath
```
public String getAggregatedFolderPath()
```
    This field is useful only for the aggregated resources of type ResourceType.CSS.
    The aggregatedFolderPath is used to compute the depth. For example, if aggregatedFolder is "wro" then the depth is 1 and the path used to prefix the image url is "..". If the aggregatedFolder is "css/aggregated", the depth is 2 and the prefix is "../..". The name of the aggregated folder is not important, it is used only to compute the depth.
    
    Specified by:
    
    getAggregatedFolderPath in interface ReadOnlyContext
    
    Returns:
    the aggregatedFolderPath
  - setAggregatedFolderPath
```
public void setAggregatedFolderPath(String aggregatedFolderPath)
```
    Parameters:
    aggregatedFolderPath - the aggregatedFolderPath to set
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
