Method Detail

fromArray

public static FieldAccessor fromArray(String name,
                                      FieldAccessor[] fieldAccessors)

Gets the FieldAccessor for the field with the given name from the given array of FieldAccessors.

Parameters:

name - ASN.1 name of the field, after any @rename adaptation

fieldAccessors - FieldAccessor[]

Returns:

FieldAccessor having the given name, or null if none

getSequenceFieldsMap

public static Map<String,Object> getSequenceFieldsMap(AbstractFieldsObject object,
                                                            FieldAccessor[] fieldAccessors,
                                                            boolean withAbsents)

Gets a Map from field-name to field-value for the fields of a sequence. For a field of primitive type, the field-value is boxed. For an absent optional field, the field-value is AbstractFieldsObject.FIELD_ABSENT. For an uninitialised mandatory field, the field-value is AbstractFieldsObject.FIELD_UNINITIALISED. For a field of String type, the encoded form is used if the String cannot be decoded. For a type that represents an OCTET STRING that cannot be decoded, a map from "encodedValue" to the byte array value is returned.

Parameters:

object - that whose fields are to be accessed

fieldAccessors - FieldAccessor[]

withAbsents - whether to put absent optional fields into Map

Returns:

Map from field-name to field-value

getChoiceFieldsMap

public static Map<String,Object> getChoiceFieldsMap(AbstractFieldsObject object,
                                                          FieldAccessor[] fieldAccessors)

Gets a Map from :discriminant-name to field-value. If choice is not set, returns a Map from : to AbstractFieldsObject.FIELD_UNINITIALISED. For a field of primitive type, the field-value is boxed. For a field of String type, the encoded form is used if the String cannot be decoded. For a type that represents an OCTET STRING that cannot be decoded, a map from "encodedValue:" to the byte array value is returned.

Parameters:

object - that whose fields are to be accessed

fieldAccessors - FieldAccessor[]

Returns:

Map from :discriminant-name to field-value
