- Method Detail
  - beginObject
```
void beginObject()
```
    Start of an object
  - yieldObject
```
void yieldObject()
```
    End of an object
  - yieldKey
```
void yieldKey()
```
    Key has been defined (likely through yieldString()).
  - beginArray
```
void beginArray()
```
    Start of an array
  - yieldArray
```
void yieldArray()
```
    End of an array
  - yieldSeparator
```
void yieldSeparator()
```
    End of an object member or array element, marked by a comma
  - yieldString
```
void yieldString(java.lang.String str)
```
    Handle a String value. Note that this String might be a key in an object. It is the handler's responsibility to detect this.
    
    Parameters:
    
    str - string
  - yieldNumber
```
void yieldNumber(double v)
```
    Handle a numeric value
    
    Parameters:
    
    v - number
  - yieldTrue
```
void yieldTrue()
```
    Handle a 'true' boolean
  - yieldFalse
```
void yieldFalse()
```
    Handle a 'false' boolean
  - yieldNull
```
void yieldNull()
```
    Handle a 'null' value
  - yieldGarbage
```
void yieldGarbage(java.lang.String str)
```
    Handle garbage. Garbage is content that doesn't satisfy the JSON spec. The most common sources of garbage are comments and String values that are not quoted.
    To facilitate handling of these two cases, we parse each 'garbage' term as follows:
    - If text starts with a // or #, the content is parsed until the end of the line
    - If text starts with a /* , the content is parsed until the closing *\/
    - Otherwise, the content is parsed until the next whitespace, colon, or comma
    Parameters:
    
    str - garbage string
  - hasElement
```
boolean hasElement()
```
    Check whether a JSON element is available
    
    Returns:
    
    true if an element can be popped
  - pop
```
java.lang.Object pop()
```
    Returns and removes the next successfully created JSON element, throws an exception if no such element exists
    
    Returns:
    
    next JSON element
  - clear
```
void clear()
```
    Clear any stored info, i.e. starting from scratch
