Constructor Detail

ByteLiteral

public ByteLiteral(QueryExpression qs,
                   JavaTypeMapping mapping,
                   java.math.BigInteger value)

Creates a byte literal

Parameters:

qs - the QueryExpression

mapping - the mapping

value - the literal 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

mod

public ScalarExpression mod(ScalarExpression expr)

Description copied from class: NumericExpression

Method to return a modulus expression.

Overrides:

mod in class NumericExpression

Parameters:

expr - The expression to modulus against

Returns:

The modulus expression

neg

public ScalarExpression neg()

Description copied from class: ScalarExpression

Unary Minus Operator

Overrides:

neg in class NumericExpression
