Class OasisXmlHandler

java.lang.Object

org.xml.sax.helpers.DefaultHandler

com.mmm.cms.homehealth.io.OasisXmlHandler

All Implemented Interfaces:

org.xml.sax.ContentHandler, org.xml.sax.DTDHandler, org.xml.sax.EntityResolver, org.xml.sax.ErrorHandler

public class OasisXmlHandler
extends org.xml.sax.helpers.DefaultHandler

In conjunction with SAX XML parsing, this collects the tags with values and then creates a record, either C or C1, based on the M0090 and the version identifier. This actually allows the XML to have more than one record, so the getRecords() may return more than one record, but according to the OASIS spec, most likely there will only be one record in the list.

void	characters(char[] chars, int startIdx, int endIdx)
void	endElement(java.lang.String uri, java.lang.String localName, java.lang.String qualifiedName) This collects the tag/values until it hits the ASSESSMENT end tag, at which point is creates the internal HH record and converts the data to the fields in the record.
void	fillInRecord(HomeHealthRecordIF record) this loops through the keys in the tagValues and applies their values to the supplied record.
void	fillInRecordValue(HomeHealthRecordIF record, java.lang.String tag, java.lang.String value) Given a specific record, it associates the named (tag) value to the related field.
java.util.List<HomeHealthRecordIF>	getRecords()
protected java.lang.reflect.Method	getSetMethod(java.lang.Object obj, java.lang.String fieldName, java.lang.Class[] params) This assumes that the methods are overloaded, so there is only one per field name.

Method Detail

getRecords

public java.util.List<HomeHealthRecordIF> getRecords()

characters

public void characters(char[] chars,
              int startIdx,
              int endIdx)
                throws org.xml.sax.SAXException

Specified by:

characters in interface org.xml.sax.ContentHandler

Overrides:

characters in class org.xml.sax.helpers.DefaultHandler

Throws:

org.xml.sax.SAXException

endElement

public void endElement(java.lang.String uri,
              java.lang.String localName,
              java.lang.String qualifiedName)
                throws org.xml.sax.SAXException

This collects the tag/values until it hits the ASSESSMENT end tag, at which point is creates the internal HH record and converts the data to the fields in the record.

Specified by:

endElement in interface org.xml.sax.ContentHandler

Overrides:

endElement in class org.xml.sax.helpers.DefaultHandler

Parameters:

uri -

localName -

qualifiedName -

Throws:

org.xml.sax.SAXException

fillInRecord

public void fillInRecord(HomeHealthRecordIF record)

this loops through the keys in the tagValues and applies their values to the supplied record.

Parameters:

record -

fillInRecordValue

public void fillInRecordValue(HomeHealthRecordIF record,
                     java.lang.String tag,
                     java.lang.String value)

Given a specific record, it associates the named (tag) value to the related field. Some fields are known to be non-String, and they are automatically converted to internal data types, such as DiagnosisCode, Calendar, or integer. In order to find the field name within the record, the "M----_" prefix of the tag is removed, which should match with the field and the get/set methods within the record object.

Parameters:

record -

tag -

value -

startElement

public void startElement(java.lang.String uri,
                java.lang.String localName,
                java.lang.String qualifiedName,
                org.xml.sax.Attributes arg3)
                  throws org.xml.sax.SAXException

Specified by:

startElement in interface org.xml.sax.ContentHandler

Overrides:

startElement in class org.xml.sax.helpers.DefaultHandler

Throws:

org.xml.sax.SAXException

                                    java.lang.Class[] params)
                                         throws java.lang.NoSuchMethodException

This assumes that the methods are overloaded, so there is only one per field name.

Parameters:

fieldName -

params -

Returns:

Throws:

java.lang.NoSuchMethodException
