Constructor Detail

FloatingPointLiteral

public FloatingPointLiteral(QueryExpression qs,
                            JavaTypeMapping mapping,
                            java.lang.Float value)
Creates a floating point literal

Parameters:
qs - the QueryExpression
mapping - the mapping
value - the floating point value

FloatingPointLiteral

public FloatingPointLiteral(QueryExpression qs,
                            JavaTypeMapping mapping,
                            java.lang.Double value)
Creates a floating point literal

Parameters:
qs - the QueryExpression
mapping - the mapping
value - the floating point value

FloatingPointLiteral

public FloatingPointLiteral(QueryExpression qs,
                            java.math.BigDecimal value)
Creates a floating point literal

Parameters:
qs - the QueryExpression
value - the floating point value
Method Detail

getValue

public java.lang.Object getValue()
Description copied from interface: Literal
Accessor to the literal value

Specified by:
getValue in interface Literal
Returns:
the value of the literal

eq

public BooleanExpression eq(ScalarExpression expr)
Description copied from class: ScalarExpression
Equality operator (equals to)

Overrides:
eq in class NumericExpression

noteq

public BooleanExpression noteq(ScalarExpression expr)
Description copied from class: ScalarExpression
Equality operator (not equals to)

Overrides:
noteq in class NumericExpression

lt

public BooleanExpression lt(ScalarExpression expr)
Description copied from class: ScalarExpression
Relational operator (lower than)

Overrides:
lt in class NumericExpression

lteq

public BooleanExpression lteq(ScalarExpression expr)
Description copied from class: ScalarExpression
Relational operator (lower than or equals)

Overrides:
lteq in class NumericExpression

gt

public BooleanExpression gt(ScalarExpression expr)
Description copied from class: ScalarExpression
Relational operator (greater than)

Overrides:
gt in class NumericExpression

gteq

public BooleanExpression gteq(ScalarExpression expr)
Description copied from class: ScalarExpression
Relational operator (greater than or equals)

Overrides:
gteq in class NumericExpression

add

public ScalarExpression add(ScalarExpression expr)
Description copied from class: ScalarExpression
Additive Operator. The binary + operator performs addition when applied to two operands of numeric type, producing the sum of the operands. If the type of either operand of a + operator is String, then the operation is string concatenation.

Overrides:
add in class NumericExpression

sub

public ScalarExpression sub(ScalarExpression expr)
Description copied from class: ScalarExpression
Additive Operator. The binary - operator subtracts right-hand operand from left-hand operand.

Overrides:
sub in class NumericExpression

mul

public ScalarExpression mul(ScalarExpression expr)
Description copied from class: ScalarExpression
Multiplication Operator

Overrides:
mul in class NumericExpression

div

public ScalarExpression div(ScalarExpression expr)
Description copied from class: ScalarExpression
Division Operator. The left-hand operand is the dividend and the right-hand operand is the divisor.

Overrides:
div in class NumericExpression

neg

public ScalarExpression neg()
Description copied from class: ScalarExpression
Unary Minus Operator

Overrides:
neg in class NumericExpression
