Class RelationalOperationInfo

java.lang.Object
  com.remedy.arsys.api.RelationalOperationInfo

All Implemented Interfaces:

java.lang.Cloneable, IARQualifierOperand

public class RelationalOperationInfo

extends java.lang.Object

implements IARQualifierOperand, java.lang.Cloneable

The RelationalOperationInfo class represents any relational operation between any ArithmeticOrRelationalOperand objects. It consists of a tag identifying the operation type and two operands specifying the values to compare.

Note This operand can be used in ArithmeticOperationInfo operations as well.

Field Summary

static int	AR_REL_OP_EQUAL Constants.AR_REL_OP_EQUAL tests whether the left operand is equal to the right operand.
static int	AR_REL_OP_GREATER Constants.AR_REL_OP_GREATER tests whether the left operand is greater than the right operand.
static int	AR_REL_OP_GREATER_EQUAL Constants.AR_REL_OP_GREATER_EQUAL tests whether the left operand is greater than or is equal to the right operand.
static int	AR_REL_OP_IN Constants.AR_REL_OP_IN tests whether the left operand is equal to the right operand.
static int	AR_REL_OP_LESS Constants.AR_REL_OP_LESS tests whether the left operand is less than the right operand.
static int	AR_REL_OP_LESS_EQUAL Constants.AR_REL_OP_LESS_EQUAL tests whether the left operand is less than or is equal to the right operand.
static int	AR_REL_OP_LIKE Constants.AR_REL_OP_LIKE tests whether the left operand is LIKE the pattern defined by the right operand.
static int	AR_REL_OP_NOT_EQUAL Constants.AR_REL_OP_NOT_EQUAL tests whether the left operand is not equal to the right operand.

Constructor Detail

RelationalOperationInfo

public RelationalOperationInfo(int operation,
                               ArithmeticOrRelationalOperand op1,
                               ArithmeticOrRelationalOperand op2)
                        throws java.lang.IllegalArgumentException

Throws:

java.lang.IllegalArgumentException - if invalid operation

Method Detail

setOperation

public void setOperation(int operation)

Sets conditional operation used.

setLeftOperand

public void setLeftOperand(ArithmeticOrRelationalOperand op)

Sets value of left operand.

setRightOperand

public void setRightOperand(ArithmeticOrRelationalOperand op)

Sets value of right operand.

getLeftOperand

public ArithmeticOrRelationalOperand getLeftOperand()

Returns value of left operand.

getRightOperand

public ArithmeticOrRelationalOperand getRightOperand()

Returns value of right operand.

getOperation

public int getOperation()

Returns conditional operation used.

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.
