                        JavaTypeMapping mapping,
                        char value)

Creates a char literal

Parameters:

qs - the QueryExpression

mapping - the mapping

value - the char value

CharacterLiteral

public CharacterLiteral(QueryExpression qs,
                        JavaTypeMapping mapping,
                        java.lang.String value)

Creates a char literal

Parameters:

qs - the QueryExpression

mapping - the mapping

value - the char 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 CharacterExpression

noteq

public BooleanExpression noteq(ScalarExpression expr)

Description copied from class: ScalarExpression

Equality operator (not equals to)

Overrides:

noteq in class CharacterExpression

lt

public BooleanExpression lt(ScalarExpression expr)

Description copied from class: ScalarExpression

Relational operator (lower than)

Overrides:

lt in class CharacterExpression

lteq

public BooleanExpression lteq(ScalarExpression expr)

Description copied from class: ScalarExpression

Relational operator (lower than or equals)

Overrides:

lteq in class CharacterExpression

gt

public BooleanExpression gt(ScalarExpression expr)

Description copied from class: ScalarExpression

Relational operator (greater than)

Overrides:

gt in class CharacterExpression

gteq

public BooleanExpression gteq(ScalarExpression expr)

Description copied from class: ScalarExpression

Relational operator (greater than or equals)

Overrides:

gteq in class CharacterExpression

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 CharacterExpression

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 CharacterExpression

mod

public ScalarExpression mod(ScalarExpression expr)

Description copied from class: CharacterExpression

Method to return a modulus expression.

Overrides:

mod in class CharacterExpression

Parameters:

expr - The expression to modulus against

Returns:

The modulus expression

toLowerCaseMethod

public CharacterExpression toLowerCaseMethod()

Converts the Character Literal to lower case

Overrides:

toLowerCaseMethod in class CharacterExpression

Returns:

the lowercased Character Literal

toUpperCaseMethod

public CharacterExpression toUpperCaseMethod()

Converts the Character Literal to upper case

Overrides:

toUpperCaseMethod in class CharacterExpression

Returns:

the uppercased Character Literal

neg

public ScalarExpression neg()

Description copied from class: ScalarExpression

Unary Minus Operator

Overrides:

neg in class CharacterExpression

com

public ScalarExpression com()

Description copied from class: ScalarExpression

Bitwise Complement Operator

Overrides:

com in class CharacterExpression
