Constructor Detail

JsonParser

public JsonParser(JsonHandler<?,?> handler)

Creates a new JsonParser with the given handler. The parser will report all parser events to this handler.

Parameters:

handler - the handler to process parser events

Method Detail

parse

public void parse(java.lang.String string)

Parses the given input string. The input must contain a valid JSON value, optionally padded with whitespace.

Parameters:

string - the input string, must be valid JSON

Throws:

ParseException - if the input is not valid JSON

parse

public void parse(java.io.Reader reader)
           throws java.io.IOException

Reads the entire input from the given reader and parses it as JSON. The input must contain a valid JSON value, optionally padded with whitespace.

Characters are read in chunks into a default-sized input buffer. Hence, wrapping a reader in an additional BufferedReader likely won't improve reading performance.

Parameters:

reader - the reader to read the input from

Throws:

java.io.IOException - if an I/O error occurs in the reader

ParseException - if the input is not valid JSON

parse

public void parse(java.io.Reader reader,
                  int buffersize)
           throws java.io.IOException

Reads the entire input from the given reader and parses it as JSON. The input must contain a valid JSON value, optionally padded with whitespace.

Characters are read in chunks into an input buffer of the given size. Hence, wrapping a reader in an additional BufferedReader likely won't improve reading performance.

Parameters:

reader - the reader to read the input from

buffersize - the size of the input buffer in chars

Throws:

java.io.IOException - if an I/O error occurs in the reader

ParseException - if the input is not valid JSON
