```
public JsonMLAst(JsonML jsonml)
```
- Method Detail
  - clearAst
```
public void clearAst()
```
    Description copied from interface: SourceAst
    
    Removes any references to root node of the AST. If it is requested again, another parse will be performed. This method is needed to allow the ASTs to be garbage collected if the inputs are still around after compilation.
    
    Specified by:
    
    clearAst in interface SourceAst
  - getAstRoot
```
public Node getAstRoot(AbstractCompiler compiler)
```
    Generates AST based on AST representation
    
    Specified by:
    
    getAstRoot in interface SourceAst
    
    See Also:
    SourceAst.getAstRoot(AbstractCompiler)
  - getSourceFile
```
public SourceFile getSourceFile()
```
    Description copied from interface: SourceAst
    
    Returns the source file the generated AST represents.
    
    Specified by:
    
    getSourceFile in interface SourceAst
  - setSourceFile
```
public void setSourceFile(SourceFile file)
```
    Description copied from interface: SourceAst
    
    Sets the source file the generated AST represents. This can be called after deserializing if access to the source file is needed. If a different file is provided than that with which this was created, an IllegalStateException will be thrown.
    
    Specified by:
    
    setSourceFile in interface SourceAst
  - getSourceName
```
public String getSourceName()
```
  - convertToJsonML
```
public JsonML convertToJsonML()
```
  - getElementPreOrder
```
public JsonML getElementPreOrder(int n)
```
    Returns a JsonML element with the specified number from the tree in pre-order walk.
    
    Returns:
    nth node or null if the node does not exists
  - getInputId
```
public InputId getInputId()
```
    Specified by:
    
    getInputId in interface SourceAst
    
    Returns:
    The input id associated with this AST
