Method Details
-
skipWhiteSpace
void skipWhiteSpace()Skip white space. -
nextChar
int nextChar()returns the next character moving the file pointer or index to the next location. -
currentChar
int currentChar()returns the current character without changing the IO pointer or index. -
hasChar
boolean hasChar()Checks to see if there is a next character. -
consumeIfMatch
boolean consumeIfMatch(char[] match)Useful for finding constants in a string like true, false, etc. -
location
int location()This is mostly for debugging and testing. -
safeNextChar
int safeNextChar()Combines the operations of nextChar and hasChar. Characters is -1 if not found which signifies end of file. This might be preferable to avoid two method calls. -
findNextChar
char[] findNextChar(int ch, int esc)Used to find strings and their ilk Finds the next non-escaped char- Parameters:
ch- character to findesc- escape character to avoid next char if escaped- Returns:
- list of chars until this is found.
-
hadEscape
boolean hadEscape() -
readNumber
char[] readNumber()Reads a number from the character source. -
errorDetails
java.lang.String errorDetails(java.lang.String message)
