Method Detail

create

public static In create(Expression columnOrExpression,
                        Expression arg)

Creates a new In Condition given left and right Expressions.

Parameters:

columnOrExpression - left hand side of the Condition must not be null.

arg - right hand side (collection Expression) must not be null.

Returns:

the In Condition.

create

public static In create(Expression columnOrExpression,
                        Collection<? extends Expression> expressions)

Creates a new In Condition given left and right Expressions.

Parameters:

columnOrExpression - left hand side of the Condition must not be null.

expressions - right hand side (collection Expression) must not be null.

Returns:

the In Condition.

create

public static In create(Expression columnOrExpression,
                        Expression... expressions)

Creates a new In Condition given left and right Expressions.

Parameters:

columnOrExpression - left hand side of the Condition must not be null.

expressions - right hand side (collection Expression) must not be null.

Returns:

the In Condition.

createNotIn

public static In createNotIn(Expression columnOrExpression,
                             Expression arg)

Creates a new In Condition given left and right Expressions.

Parameters:

columnOrExpression - left hand side of the Condition must not be null.

arg - right hand side (collection Expression) must not be null.

Returns:

the In Condition.

createNotIn

public static In createNotIn(Expression columnOrExpression,
                             Collection<? extends Expression> expressions)

Creates a new In Condition given left and right Expressions.

Parameters:

columnOrExpression - left hand side of the Condition must not be null.

expressions - right hand side (collection Expression) must not be null.

Returns:

the In Condition.

createNotIn

public static In createNotIn(Expression columnOrExpression,
                             Expression... expressions)

Creates a new In Condition given left and right Expressions.

Parameters:

columnOrExpression - left hand side of the Condition must not be null.

expressions - right hand side (collection Expression) must not be null.

Returns:

the In Condition.

not

public Condition not()

Description copied from interface: Condition

Creates a Condition that negates this Condition.

Specified by:

not in interface Condition

Returns:

the negated Condition.

hasExpressions

public boolean hasExpressions()

Returns:

true if this condition has at least one expression.

Since:

2.1

toString

public String toString()

Description copied from interface: Segment

Return a SQL string representation of this Segment.

The representation is intended for debugging purposes and an approximation to the generated SQL. While it might work in the context of a specific dialect, you should not that the Segment.toString() representation works across multiple databases.

Specified by:

toString in interface Segment

Overrides:

toString in class Object

Returns:

a SQL string representation of this Segment.

isNotIn

public boolean isNotIn()

visit

public void visit(Visitor visitor)

Description copied from interface: Visitable

Accept a Visitor visiting this Visitable and its nested Visitables if applicable.

Specified by:

visit in interface Visitable

Parameters:

visitor - the visitor to notify, must not be null.

hashCode

public int hashCode()

Description copied from interface: Segment

Generate a hash code from thisSegment.

Hashcode typically derives from the Segment.toString() representation so two Segments yield the same Segment.hashCode() if their Segment.toString() representation matches.

Specified by:

hashCode in interface Segment

Overrides:

hashCode in class Object

Returns:

a hash code value for this object.

equals

public boolean equals(Object obj)

Description copied from interface: Segment

Check whether this Segment is equal to another Segment.

Equality is typically given if the Segment.toString() representation matches.

Specified by:

equals in interface Segment

Overrides:

equals in class Object

Parameters:

obj - the reference object with which to compare.

Returns:

true if this object is the same as the other argument; false otherwise.
