Constructor Details

DefaultValidator

public DefaultValidator()

Creates a new instance of DefaultValidator

DefaultValidator

public DefaultValidator(HapiContext context)

Method Details

setValidateChildren

public void setValidateChildren(boolean validateChildren)

If set to false (default is true), each testXX and validateXX method will only test the direct object it is responsible for, not its children.

setCodeStore

public void setCodeStore(CodeStore theCodeStore)

Provides a code store to use to provide the code tables which will be used to validate coded value types. If a code store has not been set (which is the default), ProfileStoreFactory will be checked for an appropriate code store, and if none is found then coded values will not be validated.

validate

public HL7Exception[] validate(Message message,
 StaticDef profile)
                        throws ProfileException,
HL7Exception

Description copied from interface: Validator

Validates the given message against the given static definition from a conformance profile. Conformance profiles are XML representations of domain-specific constraints on a message (see HL7 2.5 section 2.12).

Specified by:

validate in interface Validator

Returns:

a list of exceptions representing points of non-conformance (may not be a complete list)

Throws:

ProfileException - if a problem is encountered that interferes with evaluation

HL7Exception

checkEventType

protected void checkEventType(String evType,
 StaticDef profile,
 List<HL7Exception> exList)

checkMessageType

protected void checkMessageType(String msgType,
 StaticDef profile,
 List<HL7Exception> exList)

checkMessageStructure

protected void checkMessageStructure(String msgStruct,
 StaticDef profile,
 List<HL7Exception> exList)

testGroup

public List<HL7Exception> testGroup(Group group,
 SegGroup profile,
 String profileID)
                             throws ProfileException

Tests a group against a group section of a profile.

Throws:

ProfileException

doTestGroup

protected List<HL7Exception> doTestGroup(Group group,
 AbstractSegmentContainer profile,
 String profileID,
 boolean theValidateChildren)
                                  throws ProfileException

Throws:

ProfileException

checkForExtraStructures

protected void checkForExtraStructures(Group group,
 List<String> allowedStructures,
 List<HL7Exception> exList)
                                throws ProfileException

Checks a group's children against a list of allowed structures for the group (ie those mentioned in the profile with usage other than X). Returns a list of exceptions representing structures that appear in the message but are not supposed to.

Throws:

ProfileException

testCardinality

protected HL7Exception testCardinality(int reps,
 int min,
 int max,
 String usage,
 String name,
 List<HL7Exception> exList)

Checks cardinality and creates an appropriate exception if out of bounds. The usage code is needed because if min cardinality is > 0, the min # of reps is only required if the usage code is 'R' (see HL7 v2.5 section 2.12.6.4).

Parameters:

reps - the number of reps

min - the minimum number of reps

max - the maximum number of reps (-1 means *)

usage - the usage code

name - the name of the repeating structure (used in exception msg)

Returns:

null if cardinality OK, exception otherwise

testStructure

public List<HL7Exception> testStructure(Structure s,
 ProfileStructure profile,
 String profileID)
                                 throws ProfileException

Tests a structure (segment or group) against the corresponding part of a profile.

Throws:

ProfileException

testSegment

public List<HL7Exception> testSegment(Segment segment,
 Seg profile,
 String profileID)
                               throws ProfileException

Tests a segment against a segment section of a profile.

Throws:

ProfileException

doTestSegment

protected List<HL7Exception> doTestSegment(Segment segment,
 Seg profile,
 String profileID,
 boolean theValidateChildren)
                                    throws ProfileException

Throws:

ProfileException

checkForExtraFields

protected void checkForExtraFields(Segment segment,
 List<Integer> allowedFields,
 List<HL7Exception> exList)
                            throws ProfileException

Checks a segment against a list of allowed fields (ie those mentioned in the profile with usage other than X). Returns a list of exceptions representing field that appear but are not supposed to.

Parameters:

allowedFields - an array of Integers containing field #s of allowed fields

Throws:

ProfileException

testType

public List<HL7Exception> testType(Type type,
 AbstractComponent<?> profile,
 String encoded,
 String profileID)

Tests a Type against the corresponding section of a profile.

Parameters:

encoded - optional encoded form of type (if you want to specify this -- if null, default pipe-encoded form is used to check length and constant val)

 String encoded,
 List<HL7Exception> exList)

protected void checkLength(long length,
 String name,
 String encoded,
 List<HL7Exception> exList)

Returns:

null of OK, an HL7Exception otherwise

testUsage

protected void testUsage(String encoded,
 String usage,
 String name,
 List<HL7Exception> exList)

Tests an element against the corresponding usage code. The element is required in its encoded form.

Parameters:

encoded - the pipe-encoded message element

usage - the usage code (e.g. "CE")

name - the name of the element (for use in exception messages)

testTypeAgainstTable

protected void testTypeAgainstTable(Type type,
