bool

public void bool(boolean bool)
          throws SAXException

Description copied from interface: JsonHandler

Reports a boolean.

Specified by:

bool in interface JsonHandler

Parameters:

bool - the boolean

Throws:

SAXException - if bad things happen

charactersImpl

private void charactersImpl(char[] ch,
                            int start,
                            int length)

public void characters(char[] ch,
                       int start,
                       int length)
                throws SAXException

Description copied from interface: JsonHandler

Adds characters to the current string started with startString().

Specified by:

characters in interface JsonHandler

Parameters:

ch - a buffer of UTF-16 code units

start - the first code unit to read

length - the number of code units to read

Throws:

SAXException - if bad things happen

endArray

public void endArray()
              throws SAXException

Description copied from interface: JsonHandler

Reports the end of an array.

Specified by:

endArray in interface JsonHandler

Throws:

SAXException - if bad things happen

endDocument

public void endDocument()
                 throws SAXException

Description copied from interface: JsonHandler

Reports the end of the JSON file. Must be called finally.

Specified by:

endString in interface JsonHandler

Throws:

SAXException - if bad things happen

key

public void key(String key)
         throws SAXException

Description copied from interface: JsonHandler

Starts a key-value pair inside an object. The parameter key gives the key and the next reported value is taken to be the value associated with the key. (Hence, there is no need for a corresponding end callback.)

Specified by:

key in interface JsonHandler

Parameters:

key - the key for the key-value pair (must not be null)

Throws:

SAXException - if bad things happen

number

Reports a number.

Specified by:

number in interface JsonHandler

Parameters:

number - the number

Throws:

SAXException - if bad things happen

number

public void number(long number)
            throws SAXException

Description copied from interface: JsonHandler

Reports a number.

Specified by:

Parameters:

number - the number

Throws:

SAXException - if bad things happen

number

public void number(float number)
            throws SAXException

Description copied from interface: JsonHandler

Reports a number.

Specified by:

Parameters:

number - the number

Throws:

number

public void number(double number)
            throws SAXException

Description copied from interface: JsonHandler

Reports a number.

Specified by:

startArray in interface JsonHandler

Throws:

SAXException - if bad things happen

startDocument

public void startDocument(String callback)
                   throws SAXException

Description copied from interface: JsonHandler

Reports the start of the JSON file. When callback is null, the file is a pure JSON file. With a non-null callback, a JSON value is wrapped in a function call named callback.

Note that the JSON null value is represented as string(null).

Specified by:

startDocument in interface JsonHandler

Parameters:

callback - JavaScript callback function name or null for pure JSON.

Throws:

SAXException - if bad things happen

startObject

public void startObject()
                 throws SAXException

Description copied from interface: JsonHandler

Reports the start of an object.

Specified by:

startObject in interface JsonHandler

startString

public void startString()
                 throws SAXException

Description copied from interface: JsonHandler

Reports the start of a string.

string

public void string(String string)
            throws SAXException

Reports a JSON null on null and a string otherwise.

When the argument is not null, this method is shorthand for

 characters(string.toCharArray(), 0, string.length());
 endString();

Specified by:

string in interface JsonHandler

Parameters:

string - a string or null

Throws:
