Interface SearchExpression

All Known Implementing Classes:

BooleanExpression, StringExpression

public interface SearchExpression

SearchExpression defines the interface that the boolean search expressions must implement. StringExpression and BooleanExpression implement this interface. StringExpression is the base of a BooleanExpression that can be evaluated. BooleanExpression is a recursive tree structure which has either more BooleanExpressions as nodes -or- StringExpressions.

Field Summary

static int	AND
static int	NAND
static int	NONE
static int	NOT
static int	OR

Method Summary

java.lang.String[]	getData() Returns the data associated with the expression.
SearchExpression	getExpression1() Returns the expression1 in a boolean operation of the form expr1 OP expr2 (where OP is any boolean operator)
SearchExpression	getExpression2() Returns the expression2 in a boolean operation of the form expr1 OP expr2 (where OP is any boolean operator)
int	getOperator() Returns the boolean operator associated with this operand.
boolean	isCaseSensitive() Returns true if the SearchExpression is case sensitive, and false otherwise.
void	print() Prints the operands.

Method Detail

getOperator

int getOperator()

Returns the boolean operator associated with this operand.

getExpression1

SearchExpression getExpression1()

Returns the expression1 in a boolean operation of the form expr1 OP expr2 (where OP is any boolean operator)

getExpression2

SearchExpression getExpression2()

Returns the expression2 in a boolean operation of the form expr1 OP expr2 (where OP is any boolean operator)

getData

java.lang.String[] getData()

Returns the data associated with the expression. This is only useful for the base case (StringExpression).

isCaseSensitive

boolean isCaseSensitive()

Returns true if the SearchExpression is case sensitive, and false otherwise.

print

void print()

Prints the operands. This is primarily used for debugging purpose.
