Set the base-pattern to the given expression

interpret

public boolean interpret(Context c)
                  throws REParserException

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:
