Class ValidatingXMLStreamReader

java.lang.Object

javax.xml.stream.util.StreamReaderDelegate

org.apache.xmlbeans.impl.validator.ValidatingXMLStreamReader

All Implemented Interfaces:

XMLStreamConstants, XMLStreamReader

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 Detail

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)

Method Detail

init

public void init(XMLStreamReader xsr,
                 boolean startWithCurrentEvent,
                 SchemaType contentType,
                 SchemaTypeLoader stl,
                 XmlOptions options,
                 Collection 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

validate_attributes

protected void validate_attributes(int attCount)

validate_attribute

protected void validate_attribute(int attIndex)

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.
