Interface ModelClassFactory

All Superinterfaces:

Serializable

All Known Implementing Classes:

CanonicalModelClassFactory, CustomModelClassFactory, DefaultModelClassFactory

public interface ModelClassFactory
extends Serializable

Looks up classes for message model components (e.g. concrete implementations of Message, Group, Segment). A custom factory can be used to point to custom model components.

Method Detail

getMessageClass

Class<? extends Message> getMessageClass(String theName,
                                         String theVersion,
                                         boolean isExplicit)
                                         throws HL7Exception

Parameters:

theName - name of message

theVersion - HL7 version

isExplicit - true if the structure was specified explicitly in MSH-9-3, false if it was inferred from MSH-9-1 and MSH-9-2. If false, a lookup may be performed to find an alternate structure corresponding to that message type and event.

Returns:

a class that implements the specified message

Throws:

HL7Exception - if the version if not recognized or an appropriate class can not be found

getMessageClassInASpecificPackage

Class<? extends Message> getMessageClassInASpecificPackage(String theName,
                                                           String theVersion,
                                                           boolean isExplicit,
                                                           String packageName)
                                                           throws HL7Exception

Retrieves and instantiates a message class by looking in a specific java package for the message type.

Parameters:

theName - The message structure type (e.g. "ADT_A01")

theVersion - The HL7 version (e.g. "2.3.1")

isExplicit - If false, the message structure is looked up using Parser.getMessageStructureForEvent(String, String) and converted to the appropriate structure type. For example, "ADT_A04" would be converted to "ADT_A01" because the A04 trigger uses the A01 message structure according to HL7.

packageName - The package name to use. Note that if the message type can't be found in this package, HAPI will return the standard type returned by getMessageClass(String, String, boolean)

Throws:

HL7Exception

Since:

1.3

getGroupClass

Class<? extends Group> getGroupClass(String theName,
                                     String theVersion)
                                     throws HL7Exception

Parameters:

theName - name of group

theVersion - HL7 version

Returns:

a class that implements the specified group

Throws:

HL7Exception - if the version if not recognized or an appropriate class can not be found

getSegmentClass

Class<? extends Segment> getSegmentClass(String theName,
                                         String theVersion)
                                         throws HL7Exception

Parameters:

theName - name of segment

theVersion - HL7 version

Returns:

a class that implements the specified segment

Throws:

HL7Exception - if the version if not recognized or an appropriate class can not be found

getTypeClass

Class<? extends Type> getTypeClass(String theName,
                                   String theVersion)
                                   throws HL7Exception

Parameters:

theName - name of type

theVersion - HL7 version

Returns:

a class that implements the specified type

Throws:

HL7Exception - if the version if not recognized or an appropriate class can not be found
