Constructor Detail

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

Method Detail

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

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
