  - push
```
int push(String context)
```
    Push a value on to the NDC stack, returning the new stack depth which should later be used to restore the stack.
    
    Parameters:
    
    context - the new value
    
    Returns:
    
    the new stack depth
  - pop
```
String pop()
```
    Pop the topmost value from the NDC stack and return it.
    
    Returns:
    
    the old topmost value
  - clear
```
void clear()
```
    Clear the thread's NDC stack.
  - trimTo
```
void trimTo(int size)
```
    Trim the thread NDC stack down to no larger than the given size. Used to restore the stack to the depth returned by a push().
    
    Parameters:
    
    size - the new size
  - getDepth
```
int getDepth()
```
    Get the current NDC stack depth.
    
    Returns:
    
    the stack depth
  - get
```
String get()
```
    Get the current NDC value.
    
    Returns:
    
    the current NDC value, or "" if there is none
  - get
```
String get(int n)
```
    Provided for compatibility with log4j. Get the NDC value that is n entries from the bottom.
    
    Parameters:
    
    n - the index
    
    Returns:
    
    the value or null if there is none
