java.lang.Objectorg.codehaus.stax2.validation.XMLValidator
com.ctc.wstx.dtd.DTDValidatorBase
public abstract class DTDValidatorBase
Shared abstract for Woodstox implementations of XMLValidator
.
Since there are 2 sub-types -- full actual DTD validator, and a dummy
one that only adds type information and default values, with no actual
validation -- common functionality was refactored into this base
class.
Field Summary | |
---|---|
protected static java.util.HashMap |
EMPTY_MAP
Let's actually just reuse a local Map... |
protected int |
mAttrCount
Number of attribute specification Objects in mAttrSpecs ; needed to store in case type information
is requested later on. |
protected DTDAttribute[] |
mAttrSpecs
List of attribute declarations/specifications, one for each attribute of the current element, for which there is a matching value (either explicitly defined, or assigned via defaulting). |
protected java.util.HashMap |
mCurrAttrDefs
Attribute definitions for attributes the current element may have |
protected DTDElement |
mCurrElem
This is the element that is currently being validated; valid during validateElementStart ,
validateAttribute ,
validateElementAndAttributes calls. |
protected int |
mElemCount
Number of elements in mElems . |
protected DTDElement[] |
mElems
Stack of element definitions matching the current active element stack. |
protected int |
mIdAttrIndex
Index of the attribute of type ID, within current element's attribute list. |
protected boolean |
mNormAttrs
Flag that indicates whether parser wants the attribute values to be normalized (according to XML specs) or not (which may be more efficient, although not compliant with the specs) |

Method Summary | |
---|---|
void |
checkNsDefaults(InputElementStack nsStack)
Method called by the input element stack to indicate that it has just added local namespace declarations from the current element, and is about to start resolving element and attribute namespace bindings. |
protected void |
doAddDefaultValue(DTDAttribute attr)
|
protected void |
doReportProblem(java.lang.String msg,
javax.xml.stream.Location loc)
|
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 (collected using the attribute collector; having DTD-derived info in same order) that is of type ID. |
protected abstract com.ctc.wstx.dtd.ElementIdMap |
getIdMap()
|
int |
getNotationAttrIndex()
Method for finding out the index of the attribute (collected using the attribute collector; having DTD-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). |
boolean |
hasNsDefaults()
|
boolean |
mayHaveNsDefaults(java.lang.String elemPrefix,
java.lang.String elemLN)
Calling this method before checkNsDefaults(com.ctc.wstx.sr.InputElementStack) is necessary
to pass information regarding the current element; although
it will become available later on (via normal XMLValidator interface),
that's too late (after namespace binding and resolving). |
abstract boolean |
reallyValidating()
|
void |
setAttrValueNormalization(boolean state)
Method that allows enabling/disabling attribute value normalization. |
abstract 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.). |
abstract 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.). |
abstract 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. |
abstract int |
validateElementEnd(java.lang.String localName,
java.lang.String uri,
java.lang.String prefix)
Method called right after encountering an element close tag. |
abstract 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. |
abstract 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). |

valueChars
- Character array that contains value (possibly
along with some other text)valueStart
- Index of the first character of the value in
in valueChars
arrayvalueEnd
- 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.

cbuf
- Character array that contains text content to validatetextStart
- Index of the first character of the content to

textEnd - textStart
).lastTextSegment
- Whether this text content is the last text
