public JSONTokener(String s)

Deprecated.

Construct a JSONTokener from a string.

Parameters:

s - A source string.

Method Detail

back

Back up one character. This provides a sort of lookahead capability, so that you can test for a digit or letter before attempting to parse the next number or identifier.

dehexchar

public static int dehexchar(char c)

Deprecated.

Get the hex value of a character (base16).

Parameters:

c - A character between '0' and '9' or between 'A' and 'F' or between 'a' and 'f'.

Returns:

An int between 0 and 15, or -1 if c was not a hex digit.

more

public boolean more()

Deprecated.

Determine if the source string still contains characters that next() can consume.

Returns:

true if not yet at the end of the source.

next

public char next()

Deprecated.

Get the next character in the source string.

Returns:

The next character, or 0 if past the end of the source string.

next

          throws JSONException

Deprecated.

JSONException - if the character does not match.

next

JSONException
