Class NumberActionCondition

java.lang.Object

oracle.ifs.utils.action.AbstractActionCondition

oracle.ifs.utils.action.NumberActionCondition

All Implemented Interfaces:

ActionCondition

public class NumberActionCondition
extends AbstractActionCondition

An ActionCondition type that operates on doubles. The left and right operands are first parsed as doubles before one of the valid operations are executed on them. Valid operations and their semantics are defined as static member variables of the class. Those operations are:

• EQUAL
• NOT_EQUAL
• GREATER_THAN
• LESS_THAN
• GREATER_THAN_EQUAL
• LESS_THAN_EQUAL

Field Summary

Fields

Modifier and Type	Field and Description
static String	EQUAL Returns true if the left and right operands are equal
static String	GREATER_THAN Returns true if the left operand is greater than the right operand
static String	GREATER_THAN_EQUAL Returns true if the left operand is greater than or equal to the right operand
static String	LESS_THAN Returns true if the left operand is less than the right operand
static String	LESS_THAN_EQUAL Returns true if the left operand is less than or equal to the right operand
static String	NOT_EQUAL Returns true if the left and right operands are not equal

Constructor Summary

Constructors

Constructor and Description
NumberActionCondition() Creates a NumberActionException that compares two double operands and registers the valid operations that can be performed on the operands.

Method Summary

Modifier and Type	Method and Description
boolean	evaluate() Parses the left and right operands as doubles, if possible, and returns true if (left_operand operation right_operand) is successful.

Constructor Detail

NumberActionCondition

public NumberActionCondition()

Creates a NumberActionException that compares two double operands and registers the valid operations that can be performed on the operands. Initializes the default operation to EQUAL and the left and right operands to zero.

Method Detail

evaluate

public boolean evaluate()

Parses the left and right operands as doubles, if possible, and returns true if (left_operand operation right_operand) is successful. Valid operations are defined as static final members of the class. The semantics of success for each operation are documented with the corrosponding member variable declarations.

Returns:

true if (left_operand operation right_operand) is successful.

Throws:

NumberFormatException - If the left or right operands cannot be be parsed as doubles.
