ClockParser

java.lang.Object
- AbstractParser

public class ClockParser extends AbstractParser

Parser for SVG Clock values, as originally defined in the SMIL spec:

Clock-val ::= Full-clock-val | Partial-clock-val
| Timecount-val
Full-clock-val ::= Hours ":" Minutes ":" Seconds ("." Fraction)?
Partial-clock-val ::= Minutes ":" Seconds ("." Fraction)?
Timecount-val ::= Timecount ("." Fraction)? (Metric)?
Metric ::= "h" | "min" | "s" | "ms"
Hours ::= DIGIT+; any positive number
Minutes ::= 2DIGIT; range from 00 to 59
Seconds ::= 2DIGIT; range from 00 to 59
Fraction ::= DIGIT+
Timecount ::= DIGIT+
2DIGIT ::= DIGIT DIGIT
DIGIT ::= [0-9]

Fields Summary
public static final int
MILLIS_PER_SECOND
Number of milliseconds in a second
public static final int
SECONDS_PER_MINUTE
Number of seconds in a minute
public static final int
MILLIS_PER_MINUTE
Number of milliseconds in a minute
public static final int

millis
Total number of milliseconds represented by this clock value.
Constructors Summary
Methods Summary
private void addHours(long hours)
Adds the given number of hours to the total clock value.
param
hours number of hours to add to the total clock value
millis += (hours * MILLIS_PER_HOUR);
private void addMillis(long ms)
Adds the given number of milliseconds to the total clock value.
param
ms number of milliseconds to add to the total clock value
millis += ms;
private void addMinutes(long minutes)
Adds the given number of minutes to the total clock value.
param
minutes number of minutes to add to the total clock value
millis += (minutes * MILLIS_PER_MINUTE);
private void addSeconds(long seconds)
Adds the given number of seconds to the total clock value.
param
seconds number of seconds to add to the total clock value
millis += (seconds * MILLIS_PER_SECOND);
public long parseClock(java.lang.String clockString)
Parses a clock value. This method throws an IllegalArgumentException if the input argument's syntax does not conform to that of a clock value, as defined by the SMIL specification.
param
clockString the value to convert to a long offset value.
return
long offset value corresponding to the input argument.
setString(clockString); current = read(); return parseClock(true);
protected long parseClock(boolean eos)
Parses a clock value, beginning at the current character.
param
eos if true, then there should be no more characters at the end of the string (excess characters will produce an IllegalArgumentException); if false, the parser will treat whitespace and ';' characters as if it marked the end of string.
return
a long offset value.
