Method Details

initCaches

protected void initCaches()

getPrimitiveRules

public Collection<PrimitiveTypeRule> getPrimitiveRules(String theVersion,
 String theTypeName,
 Primitive theType)

Specified by:

getPrimitiveRules in interface ValidationContext

Parameters:

theType - ignored

theVersion - an HL7 version (eg "2.1")

theTypeName - a primitive datatype name (eg "ST")

Returns:

active rules for checking the given type in the given version

See Also:

• ValidationContext.getPrimitiveRules(String, String, Primitive)

getPrimitiveRuleBindings

public List<RuleBinding<PrimitiveTypeRule>> getPrimitiveRuleBindings()

Returns:

a List of RuleBindings for PrimitiveTypeRules.

getMessageRules

public Collection<MessageRule> getMessageRules(String theVersion,
 String theMessageType,
 String theTriggerEvent)

Specified by:

getMessageRules in interface ValidationContext

Parameters:

theVersion - an HL7 version (eg "2.1")

theMessageType - a value valid for MSH-9-1

theTriggerEvent - a value valid fro MSH-9-2

Returns:

the active rules that apply to message of the given version, message type, and trigger event

getMessageRuleBindings

public List<RuleBinding<MessageRule>> getMessageRuleBindings()

Returns:

a List of RuleBindings for MessageRules.

getEncodingRules

public Collection<EncodingRule> getEncodingRules(String theVersion,
 String theEncoding)

Specified by:

getEncodingRules in interface ValidationContext

Parameters:

theVersion - an HL7 version (eg "2.1")

theEncoding - an encoding name (eg "VB", "XML)

Returns:

the active encoding rules that apply to the given version and encoding
