                                       ListBean LB,
                                       java.lang.Boolean validate)

This method builds a JDOM Document from the input XML file.
This method uses the JDOM libraries to parse the input document and create a valid JDOM document.
The input file is retrieved using the PB.getXmlFileName

Parameters:

PB - PropertyBean

MB - mainBean

LB - ListBean

mesBn - MessageBean

validate - A boolean: true to validate

Returns:

A valid JDom Document

getRoot

public org.jdom.Element getRoot(PropertyBean PB,
                                MainBean MB,
                                MessageBean mesBn,
                                ListBean LB,
                                org.jdom.Document doc)

This method retrieves the root element of XML input file.
The doc parameter is the XML document parsed in the parseDocument method

Parameters:

PB - PropertyBean

MB - MainBean

mesBn - MessageBean

LB - ListBean

doc - The JDOM document

Returns:

The root element or null

isNotPresent

private java.lang.Boolean isNotPresent(java.util.ArrayList list,
                                       java.lang.String supp)

This method checks whether the string supp is already in the list list

Parameters:

list - The checked list

supp - The input string

Returns:

true if the string supp is in the list list

loadNode

public void loadNode(PropertyBean PB,
                     MainBean MB,
                     MessageBean mesBn,
                     ListBean LB,
                     TableBean tabBn,
                     org.jdom.Element elem,
                     java.lang.Integer deep)

This method loads the node and parse it. This method performs the following steps:

• check the deep of input element. If deep is 1 (root element) do nothing. If deep is greater than 1 (XIF-XML significant elements):
  1. check if the father-deep-element has been already found
  2. for each new triple create the main element
  3. manage elements and attributes depending on their bitMap
• setup the TheElement bean with information about tables, sql strings...
• switch on bitMap to call the findAttribute method
• add the element to the theCore object
• iterate on XIF-XML elements

Parameters:

PB - PropertyBean

MB - MainBean

mesBn - MessageBean

LB - ListBean

tabBn - TableBean

elem - The element

deep - The indentation of the input element

findAttribute

public void findAttribute(java.lang.String[][] lObj,
                          java.lang.String[][] fatlObj,
                          PropertyBean PB,
                          MainBean MB,
                          MessageBean mesBn,
                          ListBean LB,
                          org.jdom.Element elem,
                          org.jdom.Element theParent,
                          org.jdom.Element theGranParent,
                          java.lang.String theFile,
                          java.lang.String theRelFile,
                          java.lang.Integer deep,
                          java.lang.Integer bitMap)

This method extracts attributes along with their values from XIF-XML elements.
Depending on bitMap value, element attributes are concatenate with father and/or granfather attributes. This method fills an hashTable whose key is the file containing data to load into staging and correspondence tables. The value of the hashTable is the content of such files.

• bitMap 0: the lObj input parameter contains the granfather details, while the fatlObj contains the father details. if lObj is null, this method concatenates the father identifier(s) with the element attribute values. If lObj in not null, the method concatenates granfather identifier(s) with father identifier(s) and element attribute values
• bitMap 1: input element has a simple identifier. The lObj is not null. This method concatenates the identifier with element attribute values
• bitMap 2: impossible
• bitMap 3: same behaviour as for bitMap 1
• bitMap 4: input element has no identifier but it has a relation file. The lObj is not null. This method concatenates identifier(s) of the father with element attribute values
• bitMap 5: bitMap 1 and bitMap 5
• bitMap 6: impossible
• bitMap 7: bitMap 3 and bitMap 4

Parameters:

lObj - The object which shapes the element. This parameter is linked to records in the WORK_DITMAP_ID_TABLE. If bitMap is 0, this object contains data about the granparent of the element.

fatlObj - The object which shapes the father element. This parameter is linked to records in the WORK_DITMAP_ID_TABLE

PB - The PropertyBean

MB - The MainBean

mesBn - The MessageBean

LB - The ListBean

elem - The input element

theParent - The parent of input element

theGranParent - The granparent of input element

theFile - Input file containing data for staging tables. File name is equal to element name

theRelFile - Input file containing data for correndondence staging tables. File name is equal to table name

deep - The indentation of element elem

bitMap - The bitMap of element elem

extractFromBitMap

private java.lang.String[] extractFromBitMap(java.lang.String[][] lObj,
                                             java.lang.Integer pos)

This method returns an array with values contained at column position pos.
The array is the pos-th column of lObj.

Parameters:

lObj - The input object

pos - The column, the method will extract from lObj

Returns:

an array with values contained at column position pos
