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()
Default Constructor

QualifierInfo(int operation, QualifierInfo op1, QualifierInfo op2)

                     QualifierInfo op2)
              throws java.lang.IllegalArgumentException

Constructor to represent operations between QualifierInfo objects

Throws:

java.lang.IllegalArgumentException - if invalid operation

QualifierInfo

public QualifierInfo(RelationalOperationInfo op1)

Constructor to allow relational operation

QualifierInfo

public QualifierInfo(QualifierFromFieldInfo fid)

Constructor to allow dynamic qualifier

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

setLeftOperand

public void setLeftOperand(QualifierInfo left)

Sets value of left operand.

setRightOperand

public void setRightOperand(QualifierInfo right)

Sets value of right operand.

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

Throws:

java.lang.CloneNotSupportedException

equals

public boolean equals(java.lang.Object anObject)

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

hashCode

public int hashCode()

Returns the hash code value for this instance of the current class. This method is supported as required by the general contract of Object.hashCode, for the benefit of hash tables such as those provided by java.util.Hashtable.
