Constructor Detail

JavaxTimeLiteral

public JavaxTimeLiteral(SQLStatement stmt,
                        org.datanucleus.store.mapped.mapping.JavaTypeMapping mapping,
                        String parameterName)

Constructor for a javax.time literal with a value.

Parameters:

stmt - the SQL statement

mapping - the mapping

parameterName - Name of the parameter that this represents if any (as JDBC "?")

Method Detail

eq

public BooleanExpression eq(SQLExpression expr)

Description copied from class: SQLExpression

Equality operator (equals to)

Overrides:

eq in class DelegatedExpression

Parameters:

expr - the right-hand operand

Returns:

The type of an equality expression is a boolean

ge

public BooleanExpression ge(SQLExpression expr)

Description copied from class: SQLExpression

Relational operator (greater than or equals)

Overrides:

ge in class DelegatedExpression

Parameters:

expr - the right-hand operand

Returns:

true if the value of the left-hand operand is greater than or equal the value of the right-hand operand, and otherwise is false.

gt

public BooleanExpression gt(SQLExpression expr)

Description copied from class: SQLExpression

Relational operator (greater than)

Overrides:

gt in class DelegatedExpression

Parameters:

expr - the right-hand operand

Returns:

true if the value of the left-hand operand is greater than the value of the right-hand operand, and otherwise is false.

le

public BooleanExpression le(SQLExpression expr)

Description copied from class: SQLExpression

Relational operator (lower than or equals)

Overrides:

le in class DelegatedExpression

Parameters:

expr - the right-hand operand

Returns:

true if the value of the left-hand operand is less than or equal to the value of the right-hand operand, and otherwise is false.

lt

public BooleanExpression lt(SQLExpression expr)

Description copied from class: SQLExpression

Relational operator (lower than)

Overrides:

lt in class DelegatedExpression

Parameters:

expr - the right-hand operand

Returns:

true if the value of the left-hand operand is less than the value of the right-hand operand, and otherwise is false.

ne

public BooleanExpression ne(SQLExpression expr)

Description copied from class: SQLExpression

Not equality operator (not equals to)

Overrides:

ne in class DelegatedExpression

Parameters:

expr - the right-hand operand

Returns:

The type of an equality expression is a boolean

isParameter

public boolean isParameter()

Overrides:

isParameter in class SQLExpression

setNotParameter

public void setNotParameter()

Description copied from interface: SQLLiteral

Method to set this literal as not being a parameter. If the literal if not currently a parameter then does nothing. Updates any underlying SQL to have the value.

Specified by:

setNotParameter in interface SQLLiteral
