Class JmlFPNumber

java.lang.Object
oracle.jsp.jml.JmlFPNumber

All Implemented Interfaces:

java.io.Serializable

public final class JmlFPNumber

extends java.lang.Object

implements java.io.Serializable

JmlFPNumber wraps the primitive type double in a Java bean. It has a single property, value that represents the bean's typed value. It is designed to work more effectively in JSPs than Java primitive types or their corresponding wrapper java.lang.* objects. Specifically, JmlFPNumber overcomes:

• inability to attach Java primitive types on JSP scope (objects).
• inability to declare most java.lang.* objects using <jsp:useBean>
• inability to modify a java.lang.* object's value after created.

Constructor Detail

JmlFPNumber

public JmlFPNumber()

Constructs a default JmlFPNumber object. The object's default value is 0.

JmlFPNumber

public JmlFPNumber(java.lang.String num)

Constructs a JmlFPNumber object whose value is java.lang.Integer.

JmlFPNumber

public JmlFPNumber(int num)

Constructs a JmlFPNumber object whose value is int.

JmlFPNumber

public JmlFPNumber(java.lang.Float num)

Constructs a JmlFPNumber object whose value is java.lang.Float.

JmlFPNumber

public JmlFPNumber(float num)

Constructs a JmlFPNumber object whose value is float.

JmlFPNumber

public JmlFPNumber(java.lang.Double num)

Constructs a JmlFPNumber object whose value is java.lang.Double.

JmlFPNumber

public JmlFPNumber(double num)

Constructs a JmlFPNumber object whose value is double.

JmlFPNumber

public JmlFPNumber(JmlFPNumber num)

Constructs a JmlFPNumber object whose value is JmlFPNumber.

Method Detail

getValue

public double getValue()

Returns the beans's value property as a double.

setValue

public void setValue(double num)

Sets the beans's value property to the double.

setTypedValue

public void setTypedValue(java.lang.String num)

Sets the beans's value property to the java.lang.String. Conversion occurs according to the same rules as java.lang.Double.valueOf().

setTypedValue

public void setTypedValue(java.lang.Integer num)

Sets the beans's value property to the java.lang.Integer.

setTypedValue

public void setTypedValue(int num)

Sets the beans's value property to the int.

setTypedValue

public void setTypedValue(java.lang.Float num)

Sets the beans's value property to the java.lang.Float.

setTypedValue

public void setTypedValue(float num)

Sets the beans's value property to the float.

setTypedValue

public void setTypedValue(java.lang.Double num)

Sets the beans's value property to the java.lang.Double.

setTypedValue

public void setTypedValue(double num)

Sets the beans's value property to the double.

setTypedValue

public void setTypedValue(JmlFPNumber num)

Sets the beans's value property to the JmlFPNumber.

equals

public boolean equals(double num)

Tests whether the beans's value property is equal to double.

typedEquals

public boolean typedEquals(java.lang.Integer num)

Tests whether the beans's value property is equal to java.lang.Integer.
