Constructor Detail

SubQueryConstraint

public SubQueryConstraint(AbstractValue left,
                          Query right)

Constructor for SubQueryConstraint object.

Parameters:

left - the AbstractValue on the left of the constraint

right - the Query containing the results. The query should only have one column in its results.

Method Detail

getSQLString

public java.lang.String getSQLString()

Returns a String representation of this SubQueryConstraint object, suitable for forming part of an SQL Query.

Specified by:

getSQLString in interface SQLStringable

Specified by:

getSQLString in class AbstractConstraint

Returns:

the String representation

compare

public int compare(AbstractConstraint obj,
                   java.util.Map<AbstractTable,AbstractTable> tableMap,
                   java.util.Map<AbstractTable,AbstractTable> reverseTableMap)

Compare this SubQueryConstraint with another AbstractConstraint, ignoring aliases in member fields and tables. Compare this AbstractConstraint with another, ignoring aliases in member fields and tables.

Specified by:

compare in class AbstractConstraint

Parameters:

obj - an AbstractConstraint to compare to

tableMap - a Map from tables in this constraint to tables in obj

reverseTableMap - a reverse of tableMap

Returns:

INDEPENDENT, IMPLIED_BY, IMPLIES, EQUAL, OPPOSITE, EXCLUDES, or OR, depending on the constraints.

hashCode

public int hashCode()

Overrides Object.hashCode().

Specified by:

hashCode in class AbstractConstraint

Returns:

an arbitrary integer based on the contents of the Constraint
