IndexCondition

A index condition object is made for each condition that can potentially use an index. This class does not extend expression, but in general there is one expression that maps to each index condition.

Methods
static IndexCondition	get(int compareType, ExpressionColumn column, Expression expression) Create an index condition with the given parameters.
static IndexCondition	get(int compareType, ExpressionColumn column, Expression expression) Create an index condition with the given parameters. Parameters: compareType - the comparison type, see constants in {@link Comparison} column - the column expression - the expression Returns: the index condition
static IndexCondition	getInList(ExpressionColumn column, List list) Create an index condition with the compare type IN_LIST and with the given parameters.
static IndexCondition	getInList(ExpressionColumn column, List list) Create an index condition with the compare type IN_LIST and with the given parameters. Parameters: column - the column list - the expression list Returns: the index condition
static IndexCondition	getInQuery(ExpressionColumn column, Query query) Create an index condition with the compare type IN_QUERY and with the given parameters.
static IndexCondition	getInQuery(ExpressionColumn column, Query query) Create an index condition with the compare type IN_QUERY and with the given parameters. Parameters: column - the column query - the select statement Returns: the index condition
Column	getColumn() Get the referenced column.
Column	getColumn() Get the referenced column. Returns: the column
int	getCompareType()
int	getCompareType()
ResultInterface	getCurrentResult() Get the current result of the expression.
ResultInterface	getCurrentResult() Get the current result of the expression. The rows may not be of the same type, therefore the rows may not be unique. Returns: the result
Value	getCurrentValue(Session session) Get the current value of the expression.
Value	getCurrentValue(Session session) Get the current value of the expression. Parameters: session - the session Returns: the value
Value[]	getCurrentValueList(Session session) Get the current value list of the expression.
Value[]	getCurrentValueList(Session session) Get the current value list of the expression. The value list is of the same type as the column, distinct, and sorted. Parameters: session - the session Returns: the value list
Expression	getExpression() Get expression.
Expression	getExpression() Get expression. Returns: Expression.
List	getExpressionList() Get expression list.
List	getExpressionList() Get expression list. Returns: Expression list.
Query	getExpressionQuery() Get expression query.
Query	getExpressionQuery() Get expression query. Returns: Expression query.
int	getMask(ArrayList indexConditions) Get the comparison bit mask.
int	getMask(ArrayList indexConditions) Get the comparison bit mask. Parameters: indexConditions - all index conditions Returns: the mask
String	getSQL() Get the SQL snippet of this comparison.
String	getSQL() Get the SQL snippet of this comparison. Returns: the SQL snippet
boolean	isAlwaysFalse() Check if the result is always false.
boolean	isAlwaysFalse() Check if the result is always false. Returns: true if the result will always be false
boolean	isEnd() Check if this index condition is of the type column smaller or equal to value.
boolean	isEnd() Check if this index condition is of the type column smaller or equal to value. Returns: true if this is a end condition
boolean	isEvaluatable() Check if the expression can be evaluated.
boolean	isEvaluatable() Check if the expression can be evaluated. Returns: true if it can be evaluated
boolean	isSpatialIntersects() Check if this index condition is of the type spatial column intersects value.
boolean	isSpatialIntersects() Check if this index condition is of the type spatial column intersects value. Returns: true if this is a spatial intersects condition
boolean	isStart() Check if this index condition is of the type column larger or equal to value.
boolean	isStart() Check if this index condition is of the type column larger or equal to value. Returns: true if this is a start condition
