createOrUpdateImportArea

Create or update an import area -- necessary before any tasks can be executed

Parameters

• envCtx EnvironmentContext an environment context from ibm-iis-commons
• name string name of the import area
• description string description of the import area
• bridgeName string name of the bridge to use for the import area
• dcnParams Array<Object> array of data connection parameters (each object having an 'id', 'displayName', and 'value')
• bridgeParams Array<Object> array of bridge-specific parameters (each object having an 'id', 'displayName', and 'value')

getImportAreaList

Get a list of import areas and their various last update dates

Parameters

• envCtx EnvironmentContext an environment context from ibm-iis-commons

Returns Object an object with import area names as keys, and then within each of these a sub-object of timestamps 'importTS', 'analysisTS', 'previewTS', 'shareTS'

getTemplateForBridge

Returns a template (list of headers) for the bridge specified

Parameters

• bridgeName string
• wb Workbook? an optional workbook into which to add this template

Returns any Workbook an Excel Workbook with the template

buildParameterXML

Builds the parameter XML needed by imam.sh

Parameters

• envCtx EnvironmentContext an environment context from ibm-iis-commons
• filename string name of the XML file to produce
• bridgeName string name of the bridge for which the XML file needs to be created
• dcnParamList Array<Object> array of objects describing the data connection, each with 'id', 'displayName' and 'value' properties
• paramList Array<Object> array of objects describing bridge-specific options, each with 'id', 'displayName', and 'value' properties

loadMetadata

Loads metadata from all of the sources listed in the specified Excel file -- which should have been produced first by the getTemplateForBridge function

Parameters

• envCtx EnvironmentContext an environment context from ibm-iis-commons
• filename string name of the .xlsx file containing host details, credentials, etc
• callback processCallback callback that handles the response of processing

getColumnDefinitionsFromDDL

Given DDL for defining one or more database tables, converts these into their corresponding IMAM-recognisable data formats

Parameters

• ddlFile string path to the DDL file containing one or more CREATE TABLE statements

Returns any FieldDefinitions with table names as keys, each being a sub-object with a 'header' (String) and 'columns' (String[]) properties

getHeaderLineForTable

Retrieves the header line for a given table name, from a set of converted field definitions

Parameters

• tablesToFields FieldDefinitions the set of converted field definitions from getColumnDefinitionsFromDDL
• tblName string the name of the table for which to get the header line
• delimiter string? an optional delimiter to use (by default a |)

Returns any String with the header line for a data file that will be IMAM-importable

getOSHSchemaForTable

Creates the contents for an OSH schema file for a given table name, from a set of converted field definitions

Parameters

• tablesToFields FieldDefinitions the set of converted field definitions from getColumnDefinitionsFromDDL
• tblName string the name of the table for which to create the OSH schema file
• delimiter string? an optional delimiter to use (by default a |)
• bHeader boolean? true if there is a header in the data file, false otherwise
• escape string? the string that should be treated as an escape sequence for the delimiter (e.g. a double-quote)

Returns any String with the contents for an OSH schema file that will be IMAM-importable

processCallback

This callback is invoked as the result of processing an Excel file.

Type: Function

Parameters

• result Object the result object, as returned by module:shelljs~exec
• bridgeName string name of the metadata bridge used for the load
• dcnParams Array<Object> array of data connection parameter objects that were used to load metadata, each with an 'id', 'displayName' and 'value'
• bridgeParams Array<Object> array of bridge-specific parameter objects that were used to load metadata, each with an 'id', 'displayName' and 'value'

getImplementedBridges

Retrieves a list of the bridges that can currently be handled by this module

Returns Array<string> a list of the bridge names that are currently implemented in the module

FileSchemaFactory

FileSchemaFactory class -- for encapsulating information about creating a schema heading for files

ImportParameters

ImportParameters class -- for encapsulating parameters for creating an import area in IMAM

getImportParametersDoc
