Method Detail

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 MultipleCondition

Returns:

a SQL string representation of this Segment.

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.
