- Method Detail
  - visit

    Parameters:
    
    part - The component QueryPart
    
    Throws:
    
    DataAccessException - If something went wrong while visiting the component QueryPart, e.g. when binding a variable
  - start
```
C start(Clause clause)

  - end
```
C end(Clause clause)
```

  - declareTables
```
C declareTables(boolean declareTables)
```
    Set the new context value for declareTables().

  - nextIndex
```
int nextIndex()
```
    Get the next bind index. This increments an internal counter. This is relevant for two use-cases:

    When rendering unnamed bind variables with RenderContext.paramType() being to NAMED
  - peekIndex
```
int peekIndex()
```
    Peek the next bind index. This won't increment the internal counter, unlike nextIndex().
