                  boolean escaped,
                  char escapeChar)
           throws ParseException

Method Detail

getInstance

static JmsLike getInstance(JmsIdentifier lvalue,
                           JmsStringLiteral rvalue,
                           char escapeChar)

static JmsLike getInstance(JmsIdentifier lvalue,
                           JmsStringLiteral rvalue)
                    throws ParseException

getInstanceOfLike

private static JmsLike getInstanceOfLike(JmsIdentifier lvalue,
                                         JmsStringLiteral rvalue,
                                         boolean isEscaped,
                                         char escapeChar)

Used to determine if there were any previous LIKE(s) that were logically equivelant.

---

toString

public java.lang.String toString()

Description copied from class: java.lang.Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).

---

evaluate

JmsOperand evaluate(javax.jms.Message msg)
              throws SelectorFalseException

Description copied from class: JmsOperand

Evaluates the expression tree represented by this node.

Specified by:

---

getType

short getType()

Specified by:

getType in class JmsOperand

---

unParse

java.lang.String unParse()

Description copied from class: JmsOperand

Returns a String representing the SQL form of the filter which is logically equivilant.

Overrides:

---

isEscaped

protected boolean isEscaped()

---

escapeChar

protected char escapeChar()

---

getInstanceReflective

protected static JmsBinaryOperand getInstanceReflective(short parentType,
                                                        JmsOperand lvalue,
                                                        JmsOperand rvalue)

Called when the left and the right values can be interchanged like with an equals statement.

---

getInstanceNonReflective

protected static JmsBinaryOperand getInstanceNonReflective(short parentType,
                                                           JmsOperand lvalue,
