```
public class ASTNode
extends Object
```
Base class for any AST node. This class supports basic information used in all nodes of the AST
- line and column number information. Usually a node represents a certain area in a text file determined by a starting position and an ending position. For nodes that do not represent this, this information will be -1. A node can also be configured in its line/col information using another node through setSourcePosition(otherNode).
- every node can store meta data. A phase operation or transform can use this to transport arbitrary information to another phase operation or transform. The only requirement is that the other phase operation or transform runs after the part storing the information. If the information transport is done it is strongly recommended to remove that meta data.
a text representation of this node trough getText(). This was in the past used for assertion messages. Since the usage of power asserts this method will not be called for this purpose anymore and might be removed in future versions of Groovy

```
public void setSourcePosition(ASTNode node)
```
    Sets the source position using another ASTNode. The sourcePosition consists of a line/column pair for the start and a line/column pair for the end of the expression or statement
    
    Parameters:
    node - - the node used to configure the position information
  - getNodeMetaData
```
public Object getNodeMetaData(Object key)
```
    Gets the node meta data.
    
    Parameters:
    key - - the meta data key
    
    Returns:
    the node meta data value for this key
  - copyNodeMetaData
```
public void copyNodeMetaData(ASTNode other)
```
    Copies all node meta data from one node to the other
    
    Parameters:
    other - - the other node
  - setNodeMetaData
```
public void setNodeMetaData(Object key,
                   Object value)
```
    Sets the node meta data.
    
    Parameters:
    key - - the meta data key
    value - - the meta data value
    
    Throws:
    
    GroovyBugError - if key is null or there is already meta data under that key
  - removeNodeMetaData
```
public void removeNodeMetaData(Object key)
```
    Removes a node meta data entry.
    
    Parameters:
    key - - the meta data key
    
    Throws:
    
    GroovyBugError - if the key is null
