public class QualifierInfo

extends java.lang.Object

implements IARQualifierOperand, java.lang.Cloneable

The QualifierInfo class is composed of a set of zero or more conditions that limit the set of entries retrieved. Each individual condition by using a tree structure comprised of an operation and one or two operands IARQualifierOperand (depending on the type of operation). Specific implementations of this interface are QualifierInfo and RelationalOperationInfo

Field Summary

static int	AR_COND_OP_AND A qualification using the AND operator.
static int	AR_COND_OP_FROM_FIELD A dynamic qualification using a value from a field.
static int	AR_COND_OP_MAX Indicates the number of currently used possible values (which is 5).
static int	AR_COND_OP_NONE No qualification.
static int	AR_COND_OP_NOT A qualification using the NOT operator.
static int	AR_COND_OP_OR A qualification using the OR operator.
static int	AR_COND_OP_REL_OP A qualification using a relational operator.

Constructor Summary

QualifierInfo(int operation, QualifierInfo op1, QualifierInfo op2)
Constructor to represent operations between QualifierInfo objects

QualifierInfo(QualifierFromFieldInfo fid)
Constructor to allow dynamic qualifier

QualifierInfo(RelationalOperationInfo op1)
Constructor to allow relational operation

Method Summary
