 org.apache.xmlbeans.samples.enumeration.SchemaEnum
| SchemaEnum | | public class SchemaEnum (Code) | | This sample illustrates how you can access XML values that are
defined in schema as enumerations. When a schema containing
enumerations is compiled, the generated Java types represent the
schema enumerations with Java enumerations. You can access these through
their constants and corresponding int values.
The schemas used by this sample are defined in PriceSummary.xsd and
EasyPO.xsd.

| Method Summary | |
| public static void | main(String[] args)
Receives an PO XML instance and uses its data to create an XML
document based another schema, and which summarizes the items
in the PO by price. | | public PurchaseOrderDocument | parseXml(String xmlFilePath)
Creates a File from the XML path provided in main arguments, then
parses the file's contents into a type generated from schema.
Note that this work might have been done in main. | | public String | sortByThreshold(PriceSummaryDocument summaryDoc)
This method loops through a price summary XML document to
create a string that lists the items grouped by threshold. | | public PriceSummaryDocument | summarizeItems(PurchaseOrderDocument poDoc)
This method uses values in the incoming XML to construct
a new XML document of a different schema. | | public boolean | validateXml(XmlObject xml)
Validates the XML, printing error messages when the XML is invalid. |
| main | | public static void main(String[] args)(Code) | | Receives an PO XML instance and uses its data to create an XML
document based another schema, and which summarizes the items
in the PO by price.
Parameters:
args - An array containing one argument: the path to an XML instanceconforming to the schema in EasyPO.xsd. |
| parseXml | | public PurchaseOrderDocument parseXml(String xmlFilePath)(Code) | | Creates a File from the XML path provided in main arguments, then
parses the file's contents into a type generated from schema.
Note that this work might have been done in main. Isolating it here
makes the code separately available from outside this class.
Parameters:
xmlFilePath - A path to XML based on the schema in inventory.xsd. An instance of a generated schema type that contains the parsedXML. |
| sortByThreshold | | public String sortByThreshold(PriceSummaryDocument summaryDoc)(Code) | | This method loops through a price summary XML document to
create a string that lists the items grouped by threshold.
Unlike the summarizeItems method, which creates a new XML
document that contains an attribute whose value is enumerated,
this method retrieves values from an enumeration.
This method illustrates how you can use the int value corresponding
to enumerations to specify them in Java switch statements.
|
| summarizeItems | | public PriceSummaryDocument summarizeItems(PurchaseOrderDocument poDoc)(Code) | | This method uses values in the incoming XML to construct
a new XML document of a different schema. PriceSummary.xsd, the schema
for the new document, defines XML enumerations for a price
threshold attribute. Items whose price is between $10 and $20 receive
a threshold value of "Between10And20Dollars"; items above 20 get a threshold
value of "Above20Dollars".
This method loops through the purchase order items, creating a summary
document that specifies their threshold value.
You can verify this method's work by comparing the resulting XML with
the XML in PriceSummary.xml. You can also use this method's return value
to test the sortByThreshold method.
|
| validateXml | | public boolean validateXml(XmlObject xml)(Code) | | Validates the XML, printing error messages when the XML is invalid. Note
that this method will properly validate any instance of a compiled schema
type because all of these types extend XmlObject.
Note that in actual practice, you'll probably want to use an assertion
when validating if you want to ensure that your code doesn't pass along
invalid XML. This sample prints the generated XML whether or not it's
valid so that you can see the result in both cases.
Parameters:
xml - The XML to validate. true if the XML is valid; otherwise, false |
