Method Detail

isNotNull

boolean isNotNull()
Returns the value of the 'Not Null' attribute.

If the meaning of the 'Not Null' attribute isn't clear, there really should be more of a description here...

Returns:
the value of the 'Not Null' attribute.
See Also:
setNotNull(boolean), SQLQueryModelPackage.getPredicateIsNull_NotNull()

setNotNull

void setNotNull(boolean value)
Sets the value of the 'Not Null' attribute.

Parameters:
value - the new value of the 'Not Null' attribute.
See Also:
isNotNull()

getValueExpr

QueryValueExpression getValueExpr()
Returns the value of the 'Value Expr' containment reference. It is bidirectional and its opposite is 'Predicate Null'.

If the meaning of the 'Value Expr' containment reference isn't clear, there really should be more of a description here...

Returns:
the value of the 'Value Expr' containment reference.
See Also:
setValueExpr(QueryValueExpression), SQLQueryModelPackage.getPredicateIsNull_ValueExpr(), QueryValueExpression.getPredicateNull()

setValueExpr

void setValueExpr(QueryValueExpression value)
Sets the value of the 'Value Expr' containment reference.

Parameters:
value - the new value of the 'Value Expr' containment reference.

getValueExpr()
