Method Detail

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

testGroup

public HL7Exception[] testGroup(Group group,
                                AbstractSegmentContainer profile,
                                java.lang.String profileID)
                         throws ProfileException

Tests a group against a group section of a profile.

Throws:

ProfileException

testCardinality

protected HL7Exception testCardinality(int reps,
                                       int min,
                                       int max,
                                       java.lang.String usage,
                                       java.lang.String name)

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 HL7Exception[] testStructure(Structure s,
                                    ProfileStructure profile,
                                    java.lang.String profileID)
                             throws ProfileException

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

Throws:

ProfileException

testSegment

public HL7Exception[] testSegment(Segment segment,
                                  Seg profile,
                                  java.lang.String profileID)
                           throws ProfileException

Tests a segment against a segment section of a profile.

Throws:

ProfileException

testType

public HL7Exception[] testType(Type type,
                               AbstractComponent profile,
                               java.lang.String encoded,
                               java.lang.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)

testLength

public HL7Exception testLength(Type type,
                               int maxLength)

Tests whether the given type falls within a maximum length.

Returns:

null of OK, an HL7Exception otherwise

testField

public HL7Exception[] testField(Type type,
                                Field profile,
                                boolean escape,
                                java.lang.String profileID)
                         throws ProfileException

Throws:

ProfileException

testComponent

public HL7Exception[] testComponent(Type type,
                                    Component profile,
                                    java.lang.String profileID)
                             throws ProfileException

Throws:

ProfileException
