evaluation of type and conversion.
- Specified by:
getSampleValue
in class JavaTypeMapping
- Returns:
- The sample value.
getJavaType
public java.lang.Class getJavaType()
- Description copied from class:
JavaTypeMapping
- Accessor for the java type being mapped
- Specified by:
getJavaType
in class JavaTypeMapping
- Returns:

newLiteral
public ScalarExpression newLiteral(QueryExpression qExpr,
java.lang.Object literal)
- Description copied from class:
JavaTypeMapping
- Creates a literal from an value.
A string literal is enclosed in single quotes. for example: "literal".
A string literal that includes a single quote is represented by two
single quotes. for example: "literal''s".
An exact numeric literal is a numeric value without a decimal point,

such as 7E3, -57.9E2, or a numeric value with a decimal, such as 7.,
-95.7, +6.2.
- Specified by:
newLiteral
in class JavaTypeMapping
- Parameters:
qExpr
- The Query statementliteral
- The object
- Returns:
- A Scalar Expression
newScalarExpression
public ScalarExpression newScalarExpression(QueryExpression qExpr,
LogicSetExpression expr)
- Description copied from class:
JavaTypeMapping
- Creates a expression from a field name/table.
e.g. tablename.fieldname; tablealias.fieldalias
- Specified by:
newScalarExpression
in class JavaTypeMapping
- Parameters:
qExpr
- The Query statementexpr
- the alias for the table
