public interface IEpcEncoder : INotifyPropertyChanged, 
	INotifyDataErrorInfo

Public Interface IEpcEncoder
	Inherits INotifyPropertyChanged, INotifyDataErrorInfo

public interface class IEpcEncoder : INotifyPropertyChanged, 
	INotifyDataErrorInfo

type IEpcEncoder =  
    interface
        interface INotifyPropertyChanged
        interface INotifyDataErrorInfo
    end

The IEpcEncoder type exposes the following members.

Properties

	Name	Description
	HasErrors	Gets a value that indicates whether the entity has validation errors. (Inherited from INotifyDataErrorInfo.)
	Header	Gets the header byte used by this encoder.
	Scheme	Gets the name of the encoding scheme implemented by this encoder.
	WordCount	Gets the number of words this encoder produces when encoding (VARIABLE if not fixed).

Methods

	Name	Description
	Decode	Decodes an EPC hexadecimal string and sets the fields of the encoder accordingly.
	DecodeField	Decodes a field, reading its value from a word array and setting the corresponding property.
	Encode	Encode EPC fields into corresponding words.
	EncodeField	Encodes a field returning the number of bits used.
	GetErrors	Gets the validation errors for a specified property or for the entire entity. (Inherited from INotifyDataErrorInfo.)
	SetFromTagUriString	Set encoder fields from a Tag URI.
	ToIdUriString	Method to generate the EPC Identity URI, e.g. urn:epc:id:sgtin:0614141.812345.6789
	ToTagUriString	Method to generate the EPC Tag URI, e.g. urn:epc:tag:sgtin-96:3.0614141.812345.6789

Events

	Name	Description
	ErrorsChanged	Occurs when the validation errors have changed for a property or for the entire entity. (Inherited from INotifyDataErrorInfo.)
	PropertyChanged	Occurs when a property value changes. (Inherited from INotifyPropertyChanged.)

Remarks

In addition, to implementing this interface, EPC encoders should also implement the following static fields: a string called SCHEME, e.g. "sgtin-96", a byte called HEADER e.g. 0x30 and a display name called NAME e.g. EpcStrings.Sgtin96 (referencing a property within a resource file). EPC fields should be implemented as properties annotated by an EpcFieldAttribute.
