Method Detail

generateSearchContent

public String generateSearchContent(ExtensionDefinition extensionDefinition,
                                    String documentTypeName,
                                    WorkflowAttributeDefinition attributeDefinition)

Description copied from interface: SearchableAttribute

Allows for generation of custom XML for this searchable attribute. The trigger for invocation of custom XML generation happens via the workflow API whenever a document action is taken and a request is submitted to update document XML based on searchable attribute definitions (see DocumentContentUpdate). This XML is ultimately included as part of the document's content.

It is intended that this XML can be used by the extractDocumentAttributes method in order to pull values out for indexing, though this method is free to use any source available to it for extracting data for indexing alongside a document.

A null or blank value may be returned from this method to indicate that no XML was generated.

Specified by:

generateSearchContent in interface SearchableAttribute

Parameters:

extensionDefinition - the extension definition which was used to locate and load this searchable attribute implementation

documentTypeName - the name of the document type for which this method is being invoked

attributeDefinition - contains parameters and properties that can be used to inform generation of the XML, these are supplied by the user of the workflow API when the document's searchable XML content is requested to be updated

Returns:

a String containing valid XML that should be included in the searchable attribute XML section of the document's XML content

extractDocumentAttributes

public List<DocumentAttribute> extractDocumentAttributes(ExtensionDefinition extensionDefinition,
                                                         DocumentWithContent documentWithContent)

Description copied from interface: SearchableAttribute

Extracts and returns document attributes for the given document in order to allow indexing of those values for association with the document and use in document searches. The document and it's XML content is passed to this method as that is a common source of data for indexing purposes, though implementations are free to pull data for indexing from any readily accessible source.

There are a finite set of DocumentAttribute implementations which can be returned and interpreted correctly. Client application's should not create custom extensions of the DocumentAttribute abstract class but should preferably use the DocumentAttributeFactory to construct strongly-typed document attribute instances for indexing.

Specified by:

extractDocumentAttributes in interface SearchableAttribute

Parameters:

extensionDefinition - the extension definition which was used to locate and load this searchable attribute implementation

documentWithContent - the workflow document and it's XML content

Returns:

a list of document attribute values that should be indexed for the given document, or a null or empty list if no attributes should be indexed

DocumentAttributeFactory

getSearchFields

public List<RemotableAttributeField> getSearchFields(ExtensionDefinition extensionDefinition,
                                                     String documentTypeName)

Description copied from interface: SearchableAttribute

Returns a list of RemotableAttributeField objects which define which searchable attribute criteria fields should be included in the criteria section of the document search user interface for this searchable attribute.

Specified by:

getSearchFields in interface SearchableAttribute

Parameters:

extensionDefinition - the extension definition which was used to locate and load this searchable attribute implementation

documentTypeName - the name of the document type for which this method is being invoked

Returns:

a list of remotable attribute fields which define the search fields that should be included in the document search criteria, or a null or empty list if no criteria should be included for this searchable attribute

getSearchingRows

protected List<Row> getSearchingRows(String documentTypeName)

Produces legacy KNS rows to use for search attributes. This method was left intact to help ease conversion until KNS is replaced with KRAD.

validateDocumentAttributeCriteria

public List<RemotableAttributeError> validateDocumentAttributeCriteria(ExtensionDefinition extensionDefinition,
                                                                       DocumentSearchCriteria documentSearchCriteria)

Description copied from interface: SearchableAttribute

Performs custom validation of document attribute values that come from this searchable attribute whenever a document search is performed against a document type which uses this searchable attribute. This hook allows for any desired validation of this searchable attributes custom document attribute values to be performed prior to the execution of the document search.

The entire DocumentSearchCriteria is passed to this method, though it's intended that implementing code will pull out the document attribute values on the criteria which are managed by this searchable attribute and perform any desired validation. However, there are certainly no restrictions on this method that would prevent it from performing validations outside of this scope and in relation to other portions of the criteria, though this is certainly not the intent of this validation hook.

Note that this method is invoked when performing a document search from the user interface as well as via the WorkflowDocumentService api.

Specified by:

validateDocumentAttributeCriteria in interface SearchableAttribute

Parameters:

extensionDefinition - the extension definition which was used to locate and load this searchable attribute implementation

documentSearchCriteria - the criteria that was submitted to the document search and against which validation is requested

Returns:

a list of attribute errors containing and validation failure errors messages for the relevant document attributes, if this returns a null or empty list it means that validation was successful

retrieveValidationErrorsFromGlobalVariables

protected void retrieveValidationErrorsFromGlobalVariables(List<RemotableAttributeError> validationErrors)

Retrieves validation errors from GlobalVariables MessageMap and appends to the given list of RemotableAttributeError

Parameters:

validationErrors - list to append validation errors
