static int | dehexchar (char c) |
A JSONTokener takes a source string and extracts characters and tokens from it. It is used by the JSONObject and JSONArray constructors to parse JSON source strings.
JSONTokener | ( | Reader | reader | ) |
Construct a JSONTokener from a Reader.
reader | A reader. |
JSONTokener | ( | InputStream | inputStream | ) | throws JSONException |
Construct a JSONTokener from an InputStream.
JSONTokener | ( | String | s | ) |
Construct a JSONTokener from a string.
s | A source string. |
void back | ( | ) | throws JSONException |
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.
|
static |
Get the hex value of a character (base16).
c | A character between '0' and '9' or between 'A' and 'F' or between 'a' and 'f'. |
boolean end | ( | ) |
boolean more | ( | ) | throws JSONException |
Determine if the source string still contains characters that next() can consume.
char next | ( | ) | throws JSONException |
Get the next character in the source string.
char next | ( | char | c | ) | throws JSONException |
Consume the next character, and check that it matches a specified character.
c | The character to match. |
JSONException | if the character does not match. |
String next | ( | int | n | ) | throws JSONException |
Get the next n characters.
n | The number of characters to take. |
JSONException | Substring bounds error if there are not n characters remaining in the source string. |
char nextClean | ( | ) | throws JSONException |
Get the next char in the string, skipping whitespace.
JSONException |
String nextString | ( | char | quote | ) | throws JSONException |
Return the characters up to the next close quote character. Backslash processing is done. The formal JSON format does not allow strings in single quotes, but an implementation is allowed to accept them.
quote | The quoting character, either " (double quote) or ' (single quote). |
JSONException | Unterminated string. |
String nextTo | ( | char | delimiter | ) | throws JSONException |
Get the text up but not including the specified character or the end of line, whichever comes first.
delimiter | A delimiter character. |
String nextTo | ( | String | delimiters | ) | throws JSONException |
Get the text up but not including one of the specified delimiter characters or the end of line, whichever comes first.
delimiters | A set of delimiter characters. |
Object nextValue | ( | ) | throws JSONException |
Get the next value. The value can be a Boolean, Double, Integer, JSONArray, JSONObject, Long, or String, or the JSONObject.NULL object.
JSONException | If syntax error. |
char skipTo | ( | char | to | ) | throws JSONException |
Skip characters until the next character is the requested character. If the requested character is not found, no characters are skipped.
to | A character to skip to. |
JSONException syntaxError | ( | String | message | ) |
Make a JSONException to signal a syntax error.
message | The error message. |
String toString | ( | ) |
Make a printable string of this JSONTokener.
