java.lang.Objectorg.codehaus.stax2.validation.XMLValidator
com.ctc.wstx.msv.RelaxNGValidator
public class RelaxNGValidator
Actual non-shareable validator instance, that is bound to an XML document, or document subset.
Some notes about implementation: (a) Some properties of RelaxNG model are used for optimization: for example, since text content in mixed-content models is not really validated for content, we only combine text segments between start and end tags (in any combination) -- full textual content between matching start and end tags is not necessarily collected (or rather, if there are child elements, is NEVER collected).

Method Summary | |
---|---|
java.lang.String |
getAttributeType(int index)
Method for getting schema-specified type of an attribute, if information is available. |
int |
getIdAttrIndex()
Method for finding out the index of the attribute that is of type ID; derived from DTD, W4C Schema, or some other validation source. |
int |
getNotationAttrIndex()
Method for finding out the index of the attribute (collected using the attribute collector; having DTD/Schema-derived info in same order) that is of type NOTATION. |
XMLValidationSchema |
getSchema()
Returns the schema instance that created this validator object, if known (and applicable). |
java.lang.String |
validateAttribute(java.lang.String localName,
java.lang.String uri,
java.lang.String prefix,
char[] valueChars,
int valueStart,
int valueEnd)
Callback method called on validator to give it a chance to validate the value of an attribute, as well as to normalize its value if appropriate (remove leading/trailing/intervening white space for certain token types etc.). |
java.lang.String |
validateAttribute(java.lang.String localName,
java.lang.String uri,
java.lang.String prefix,
java.lang.String value)
Callback method called on validator to give it a chance to validate the value of an attribute, as well as to normalize its value if appropriate (remove leading/trailing/intervening white space for certain token types etc.). |
int |
validateElementAndAttributes()
Method called after calling XMLValidator.validateAttribute(java.lang.String, java.lang.String, java.lang.String, java.lang.String) on all
attributes (if any), but before starting to handle element
content. |
int |
validateElementEnd(java.lang.String localName,
java.lang.String uri,
java.lang.String prefix)
Method called right after encountering an element close tag. |
void |
validateElementStart(java.lang.String localName,
java.lang.String uri,
java.lang.String prefix)
Method called to update information about the newly encountered (start) element. |
void |
validateText(char[] cbuf,
int textStart,
int textEnd,
boolean lastTextSegment)
Method called to validate textual content. |
void |
validateText(java.lang.String text,
boolean lastTextSegment)
Method called to validate textual content. |
void |
validationCompleted(boolean eod)
Method called when the validation is completed; either due to the input stream ending, or due to an explicit 'stop validation' request by the application (via context object). |

will return null since it 'contains' multiple validators
and generally does not have just one parent or owner schema.

valueChars
- Character array that contains value (possibly

- Index of the first character of the value in

- Index of the character AFTER the last character;
so that the length of the value String is

XMLValidator
Note: this method is only guaranteed to be called when
XMLValidator.validateElementAndAttributes()
for the currently open
element returned XMLValidator.CONTENT_ALLOW_VALIDATABLE_TEXT
(or,
in case of mixed content, XMLValidator.validateElementEnd(java.lang.String, java.lang.String, java.lang.String)
, for the
last enclosed element). Otherwise, validator context may choose
not to call the method as an optimization.
validateText
in class XMLValidator
text
- Text content to validatelastTextSegment
- Whether this text content is the last text
segment before a close element; true if it is, false if it is not,
or no determination can be made. Can be used for optimizing
validation -- if this is true, no text needs to be buffered since
no more will be sent before the current element closes.

validateText
in class XMLValidator
cbuf
- Character array that contains text content to validatetextStart
- Index of the first character of the content to
validatetextEnd
- Character following the last character of the
content to validate (that is, length of content to validate is
textEnd - textStart
).lastTextSegment
- Whether this text content is the last text
segment before a close element; true if it is, false if it is not,

validationCompleted
in class XMLValidator
eod
- Flag that indicates whether this method was called by the
context due to the end of the stream (true); or by an application
requesting end of validation (false).
