Method Detail

getValue

public java.lang.String getValue()

Get the value of this FormulaInfo.

Returns:

the value of this FormulaInfo.

getMappingName

public java.lang.String getMappingName()

Get the name of this FormulaInfo.

Returns:

the name of this FormulaInfo.

getExpression

public java.lang.String getExpression()

Get the expression of this FormulaInfo.

Returns:

the expression of this FormulaInfo.

isNonSQLCriterion

public boolean isNonSQLCriterion()

Deprecated since v6.1. Check if this formula needs to be handled or not when creating a SQL string. For a simple formula, like:

           return @"Customers_Customer ID";
        

it is easy to translate into Customers.`Customer ID` and it is also valid to form a valid SQL criterion like:

           Customers.`Customer ID` = 15;
        

So if this formula is inserted in SQL criterion, we call it a SQL criterion formula. But for other complecated formulas, for example, having "if else" statement, they can not be contained in the final SQL string. If inserting such a complected formula in SQL criterion, we call it a non SQL criterion formula. Non SQL criterion formulas are handled in JReport, so users need not to handle criteria that have non SQL criterion formulas when creating SQL string.

Returns:

true if this formula is a non SQL criterion formula and is inserted in SQL criterion, otherwise false.

toString

public java.lang.String toString()

Returns a string representing this FormulaInfo's values. The format is as follows:

  className@hashCode[ mappingName | expression | isNonSQLCriterion ]
        

Overrides:

toString in class java.lang.Object

Returns:

a string representing of this FormulaInfo.
