Class ValueDiscriminator

java.lang.Object oracle.dss.rules.discriminator.ValueDiscriminator

All Implemented Interfaces:: java.io.Serializable, java.lang.Cloneable, Discriminator, DiscriminatorXML

Direct Known Subclasses:: DateValueDiscriminator, NumberValueDiscriminator, StringValueDiscriminator

public abstract class ValueDiscriminator

extends java.lang.Object

implements DiscriminatorXML

Abstract Discriminator for a rule that applies based on a comparison of two values. Concrete subclasses of this class specify the kind of value and how the value from the DataView must relate to this value for the DiscriminatorRule to apply. For example, a NumberValueDiscriminator can specify that a DiscriminatorRule should apply to data values greater than 500,000.

This class defines constants for the following relational operators: =, <, <=, >, >=, >, and !=. This class is abstract because it does not define the applies method from the Discriminator interface. Discriminators that extend this class must implement the method.

Field Detail

m_relOperator

protected int m_relOperator

For internal use only. Application developers should not use this

EQ

public static final int EQ

Equals (=). The left operand (from the RuleContext) must equal the right operand (from this ValueDiscriminator).

See Also:: Constant Field Values

LT

public static final int LT

Less than (<). The left operand (from the RuleContext) must be less than the right operand (from this ValueDiscriminator). For dates, the left operand must be earlier than the right operand.

See Also:: Constant Field Values

LE

public static final int LE

Less than or equal to (<=). The left operand (from the RuleContext) must be less than or equal to the right operand (from this ValueDiscriminator). For dates, the left operand must be earlier than or equal to the right operand.

See Also:: Constant Field Values

GT

public static final int GT

Greater than (>). The left operand (from the RuleContext) must be greater than the right operand (from this ValueDiscriminator). For dates, the left operand must be later than the right operand.

See Also:: Constant Field Values

GE

public static final int GE

Greater than or equal to (>=). The left operand (from the RuleContext) must be greater than or equal to the right operand (from this ValueDiscriminator). For dates, the left operand must be later than or equal to the right operand.
