Class QualifierInfo

java.lang.Object
  |
  +--com.remedy.arsys.api.QualifierInfo

All Implemented Interfaces:

java.lang.Cloneable, IARQualifierOperand

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

java.lang.Object	clone() Clone implementation that returns an Object with data cloned from self
boolean	equals(java.lang.Object anObject) Use this method for checking equality.
QualifierFromFieldInfo	getFromFieldInfo() Returns field ID/value pair information.
QualifierInfo	getLeftOperand() Returns value of left operand.
QualifierInfo	getNotOperand() Helper function to return the operand associated in NOT operation
int	getOperation() Returns operation used in qualification.
RelationalOperationInfo	getRelationalOperationInfo() Helper function to return RelationalOperationInfo object
QualifierInfo	getRightOperand() Returns value of right operand.
int	hashCode() This method can be used to populate a hash table.
void	setOperation(int op) Sets operation used in qualification.

Method Detail

getOperation

public int getOperation()

Returns operation used in qualification.

setOperation

public void setOperation(int op)

Sets operation used in qualification. The following operation constant values can be set:

• Constants.AR_COND_OP_NONE
• Constants.AR_COND_OP_AND
• Constants.AR_COND_OP_OR
• Constants.AR_COND_OP_NOT
• Constants.AR_COND_OP_REL_OP

getLeftOperand

public QualifierInfo getLeftOperand()

Returns value of left operand.

getRightOperand

public QualifierInfo getRightOperand()

Returns value of right operand.

getNotOperand

public QualifierInfo getNotOperand()

Helper function to return the operand associated in NOT operation

getRelationalOperationInfo

public RelationalOperationInfo getRelationalOperationInfo()

Helper function to return RelationalOperationInfo object

getFromFieldInfo

public QualifierFromFieldInfo getFromFieldInfo()

Returns field ID/value pair information.

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

Clone implementation that returns an Object with data cloned from self

Overrides:

clone in class java.lang.Object

equals

public boolean equals(java.lang.Object anObject)

Use this method for checking equality. The result is true if and only if the argument is not null, is of same type and represents the same content.

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

This method can be used to populate a hash table. Implicitly used method to test equality of objects.

Overrides:

hashCode in class java.lang.Object
