All Implemented Interfaces:

Direct Known Subclasses:

ValidatingInfoXMLStreamReader

public class ValidatingXMLStreamReader
extends StreamReaderDelegate
implements XMLStreamReader

This class is a wrapper over a generic XMLStreamReader that provides validation. There are 3 cases:
1) the XMLStreamReader represents a document, it contains only one element document - in this case the user schema type should be null or it should be a document SchemaType
2) the XMLStreamReader represents an xml-fragment (content only) - must have at least one user type or xsi:type
a) it has an xsi:type - if user schema type is available it has to be a base type of xsi:type
b) it doesn't have xsi:type - user must provide a schema type otherwise will error and will not do validation
3) the XMLStreamReader represents a global attribute - i.e. user schema type is null and only one attribute

Constructor Details

ValidatingXMLStreamReader

public ValidatingXMLStreamReader()

Default constructor. Use init(...) to set the params. See init(javax.xml.stream.XMLStreamReader, boolean, org.apache.xmlbeans.SchemaType, org.apache.xmlbeans.SchemaTypeLoader, org.apache.xmlbeans.XmlOptions, java.util.Collection<org.apache.xmlbeans.XmlError>)

Method Details

init

public void init(XMLStreamReader xsr,
 boolean startWithCurrentEvent,
 SchemaType contentType,
 SchemaTypeLoader stl,
 XmlOptions options,
 Collection<XmlError> errorListener)

Used in case of reusing the same ValidatinXMLStreamReader object

Parameters:

xsr - The stream to be validated

startWithCurrentEvent - Validation will start if true with the current event or if false with the next event in the stream

contentType - The schemaType of the content. This can be null for document and global Att validation

stl - SchemaTypeLoader context of validation

options - Validator options

errorListener - Errors and warnings listener

getProperty

public Object getProperty(String s)
                   throws IllegalArgumentException

Specified by:

getProperty in interface XMLStreamReader

Overrides:

getProperty in class StreamReaderDelegate

Throws:

IllegalArgumentException

next

public int next()
         throws XMLStreamException

Specified by:

next in interface XMLStreamReader

Overrides:

next in class StreamReaderDelegate

Throws:

XMLStreamException

isValid

public boolean isValid()

Returns:

Returns the validation state up to this point. NOTE: At least one START ELEMENT should have been consumed for a valid value to be returned.
