RepeatExpression
public RepeatExpression(AbstractRegularExpression expr,
int repeat,
int mode)
- Parameters:
repeat
- number of times this expression has to be found sequentially ;mode
- EXACTLY, AT_LEAST or AT_MOST
setPattern
public void setPattern(AbstractRegularExpression expr)
- set the base-pattern to the given expression
interpret
public boolean interpret(Context c)
throws REParserException
- Description copied from class:
AbstractRegularExpression
- Parses this expression, possibly using the given Context to fetch the String to interpret
if this Expression is a leaf expression.
- Specified by:
interpret
in class AbstractRegularExpression
- Returns:
- TRUE if and only if the given "expr" has been found as many times as specified by
the "mode" given in the constructor.
If TRUE, calls action with : key="*", value=new Integer(number of effective repeat found)
- Throws:
REParserException
- if an error occur during parsing
