Specified by:

getFieldNumber in class ISOComponent

setValue

public void setValue(java.lang.Object obj)
              throws ISOException

Specified by:

setValue in class ISOComponent

Throws:

ISOException

set

public void set(ISOComponent c)
         throws ISOException

Description copied from class: ISOComponent

Set a field within this message

Overrides:

set in class ISOComponent

c - - a component

Throws:

ISOException

unset

public void unset(int fldno)
           throws ISOException

Unset a field

Overrides:

unset in class ISOComponent

Parameters:

fldno - - the field number

Throws:

getComposite

public ISOComponent getComposite()

Description copied from class: ISOComponent

In order to interchange Composites and Leafs we use getComposite(). A Composite component returns itself and a Leaf returns null. The base class ISOComponent provides Leaf functionality.

Overrides:

getComposite in class ISOComponent

Returns:

ISOComponent

getKey

public java.lang.Object getKey()
                        throws ISOException

Description copied from class: ISOComponent

valid on Leafs only. The value returned is used by ISOMsg as a key to this field.

Overrides:

getKey in class ISOComponent

Returns:

object representing the field number

Throws:

ISOException

getValue

public java.lang.Object getValue()
                          throws ISOException

Description copied from class: ISOComponent

valid on Leafs only.

Overrides:

getValue in class ISOComponent

Returns:

object representing the field value

Throws:

ISOException

getBytes

public byte[] getBytes()
                throws ISOException

Description copied from class: ISOComponent

get Value as bytes (when possible)

Overrides:

getBytes in class ISOComponent

Returns:

byte[] representing this field

Throws:

ISOException

getMaxField

public int getMaxField()

Description copied from class: ISOComponent

a Composite must override this function

Overrides:

getMaxField in class ISOComponent

Returns:

the max field number associated with this message

getChildren

Description copied from class: ISOComponent

dummy behaviour - return empty map

Overrides:

getChildren in class ISOComponent

Returns:

children (in this case 0 children)
