Negate

public Negate()

Method Detail

getExpression

public Expression getExpression()

Get expression to negate.

Returns:

Expression to negate.

setExpression

public void setExpression(Expression expression)

Set expression to negate.

Parameters:

expression - Expression to negate.

negate

public Expression negate()

Negate.

Specified by:

negate in interface Expression

Overrides:

negate in class AbstractExpression

Returns:

The Expression of query objects

toString

public StringBuilder toString(StringBuilder sb)

Append a string representation of the object to the given StringBuilder. In general, the toString method for query objects appends a string that textually represents this object. The result should be a query string that complies to EJB QL specification as long as the query object represents a syntay element of it. It is required that all subclasses override this method. The toString method defined at class Object is overwritten and calls this method.

Parameters:

sb - StringBuilder to append the string representation of this object to.

Returns:

Same instance of StringBuilder given as parameter.
