                            java.lang.IllegalAccessException

Returns the value of the field represented by this Field, on

the specified object. The value is automatically wrapped in an

object if it has a primitive type.

The underlying field's value is obtained as follows:

If the underlying field is a static field, the obj argument

is ignored; it may be null.

Otherwise, the underlying field is an instance field. If the

specified obj argument is null, the method throws a

NullPointerException. If the specified object is not an

instance of the class or interface declaring the underlying

field, the method throws an IllegalArgumentException.

If this Field object is enforcing Java language access control, and

the underlying field is inaccessible, the method throws an

IllegalAccessException.

If the underlying field is static, the class that declared the

field is initialized if it has not already been initialized.

Otherwise, the value is retrieved from the underlying instance

or static field. If the field has a primitive type, the value

is wrapped in an object before being returned, otherwise it is

returned as is.

If the field is hidden in the type of obj,

the field's value is obtained according to the preceding rules.

set

public void set(java.lang.Object obj,
                java.lang.Object value)
         throws java.lang.IllegalArgumentException,
                java.lang.IllegalAccessException

Sets the field represented by this Field object on the

specified object argument to the specified new value. The new

value is automatically unwrapped if the underlying field has a

primitive type.

The operation proceeds as follows:

If the underlying field is static, the obj argument is

ignored; it may be null.

Otherwise the underlying field is an instance field. If the

specified object argument is null, the method throws a

NullPointerException. If the specified object argument is not

an instance of the class or interface declaring the underlying

field, the method throws an IllegalArgumentException.

If this Field object is enforcing Java language access control, and

the underlying field is inaccessible, the method throws an

IllegalAccessException.

If the underlying field is final, the method throws an

IllegalAccessException unless setAccessible(true)

has succeeded for this Field object

and the field is non-static. Setting a final field in this way

is meaningful only during deserialization or reconstruction of

instances of classes with blank final fields, before they are

made available for access by other parts of a program. Use in

any other context may have unpredictable effects, including cases

in which other parts of a program continue to use the original

value of this field.

If the underlying field is of a primitive type, an unwrapping

conversion is attempted to convert the new value to a value of

a primitive type. If this attempt fails, the method throws an

IllegalArgumentException.

If, after possible unwrapping, the new value cannot be

converted to the type of the underlying field by an identity or

widening conversion, the method throws an

IllegalArgumentException.

If the underlying field is static, the class that declared the

field is initialized if it has not already been initialized.

The field is set to the possibly unwrapped and widened new value.

If the field is hidden in the type of obj,

the field's value is set according to the preceding rules.

Parameters:

obj - the object whose field should be modified

value - the new value for the field of obj

being modified

Throws:

java.lang.IllegalAccessException - if this Field object

is enforcing Java language access control and the underlying

field is either inaccessible or final.

java.lang.IllegalArgumentException - if the specified object is not an

instance of the class or interface declaring the underlying

field (or a subclass or implementor thereof),

or if an unwrapping conversion fails.

java.lang.NullPointerException - if the specified object is null

and the field is an instance field.

java.lang.ExceptionInInitializerError - if the initialization provoked

by this method fails.

                   int i)
            throws java.lang.IllegalArgumentException,
                   java.lang.IllegalAccessException

Sets the value of a field as an int on the specified object.

This method is equivalent to

set(obj, iObj),

where iObj is a Integer object and

iObj.intValue() == i.

Parameters:

obj - the object whose field should be modified

i - the new value for the field of obj

being modified

Throws:

java.lang.IllegalAccessException - if this Field object

is enforcing Java language access control and the underlying

field is either inaccessible or final.

java.lang.IllegalArgumentException - if the specified object is not an

instance of the class or interface declaring the underlying

field (or a subclass or implementor thereof),

or if an unwrapping conversion fails.

java.lang.NullPointerException - if the specified object is null

and the field is an instance field.

java.lang.ExceptionInInitializerError - if the initialization provoked

by this method fails.

             throws java.lang.IllegalArgumentException,
                    java.lang.IllegalAccessException

Sets the value of a field as a long on the specified object.

This method is equivalent to

set(obj, lObj),

where lObj is a Long object and

lObj.longValue() == l.

Parameters:

obj - the object whose field should be modified

l - the new value for the field of obj

being modified

Throws:

java.lang.IllegalAccessException - if this Field object

is enforcing Java language access control and the underlying

field is either inaccessible or final.

java.lang.IllegalArgumentException - if the specified object is not an

instance of the class or interface declaring the underlying

field (or a subclass or implementor thereof),

or if an unwrapping conversion fails.

java.lang.NullPointerException - if the specified object is null

and the field is an instance field.

java.lang.ExceptionInInitializerError - if the initialization provoked

by this method fails.

                     java.lang.IllegalAccessException

Sets the value of a field as a float on the specified object.

This method is equivalent to

set(obj, fObj),

where fObj is a Float object and

fObj.floatValue() == f.

Parameters:

obj - the object whose field should be modified

f - the new value for the field of obj

being modified

Throws:

java.lang.IllegalAccessException - if this Field object

is enforcing Java language access control and the underlying

field is either inaccessible or final.

java.lang.IllegalArgumentException - if the specified object is not an

instance of the class or interface declaring the underlying

field (or a subclass or implementor thereof),

or if an unwrapping conversion fails.

java.lang.NullPointerException - if the specified object is null

and the field is an instance field.

java.lang.ExceptionInInitializerError - if the initialization provoked

by this method fails.

                      java.lang.IllegalAccessException

Sets the value of a field as a double on the specified object.

This method is equivalent to

set(obj, dObj),

where dObj is a Double object and

dObj.doubleValue() == d.

Parameters:

obj - the object whose field should be modified

d - the new value for the field of obj

being modified

Throws:

java.lang.IllegalAccessException - if this Field object

is enforcing Java language access control and the underlying

field is either inaccessible or final.
