public class DTDTypingNonValidator
extends DTDValidatorBase

This class is a "non-validating validator"; a validator-like object that handles DTD-based non-validation functionality: determining type information and default values. This instance does NOT implement any actual DTD-validation, and is to be used in DTD-aware non-validating mode.


Field Summary
protected  java.util.BitSet mCurrDefaultAttrs
          Bitset used for keeping track of defaulted attributes for which values have been found.
protected  boolean mHasAttrDefaults
          Flag that indicates if current element has any attributes that have default values.
protected  boolean mHasNormalizableAttrs
          Flag that indicates whether any of the attributes is potentially normalizable, and we are in attribute-normalizing mode.

Field Detail

mHasAttrDefaults

protected boolean mHasAttrDefaults
Flag that indicates if current element has any attributes that have default values.


mCurrDefaultAttrs

protected java.util.BitSet mCurrDefaultAttrs
Bitset used for keeping track of defaulted attributes for which values have been found. Only non-null when current element does have such attributes


mHasNormalizableAttrs

protected boolean mHasNormalizableAttrs
Flag that indicates whether any of the attributes is potentially normalizable, and we are in attribute-normalizing mode.

Constructor Detail

DTDTypingNonValidator

public DTDTypingNonValidator(DTDSubset schema,
                             ValidationContext ctxt,
                             boolean hasNsDefaults,
                             java.util.Map elemSpecs,
                             java.util.Map genEntities)
Method Detail

reallyValidating

public final boolean reallyValidating()
Specified by:
reallyValidating in class DTDValidatorBase
Returns:
False, since this is not a real validator

setAttrValueNormalization

public void setAttrValueNormalization(boolean state)
This 'validator' will not normalize any attributes, so let's implement this as no-op.

Overrides:
setAttrValueNormalization in class DTDValidatorBase

validateElementStart

public void validateElementStart(java.lang.String localName,
                                 java.lang.String uri,
                                 java.lang.String prefix)
                          throws XMLValidationException
Description copied from class: DTDValidatorBase
Method called to update information about the newly encountered (start) element. At this point namespace information has been resolved, but no DTD validation has been done. Validator is to do these validations, including checking for attribute value (and existence) compatibility.

Specified by:
validateElementStart in class DTDValidatorBase
Throws:
XMLValidationException

validateAttribute

public java.lang.String validateAttribute(java.lang.String localName,
                                          java.lang.String uri,
                                          java.lang.String prefix,
                                          java.lang.String value)
                                   throws XMLValidationException
Description copied from class: XMLValidator
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.).

Specified by:
validateAttribute in class DTDValidatorBase
Returns:
Null, if the passed value is fine as is; or a String, if it needs to be replaced. In latter case, caller will replace the value before passing it to other validators. Also, if the attribute value is accessible via caller (as is the case for stream readers), caller should return this value, instead of the original one.
Throws:
XMLValidationException

validateAttribute

public java.lang.String validateAttribute(java.lang.String localName,
                                          java.lang.String uri,
                                          java.lang.String prefix,
                                          char[] valueChars,
                                          int valueStart,
                                          int valueEnd)
                                   throws XMLValidationException
Description copied from class: XMLValidator
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.).

Specified by:
validateAttribute in class DTDValidatorBase
valueChars - Character array that contains value (possibly along with some other text)
valueStart - Index of the first character of the value in in valueChars array
valueEnd - Index of the character AFTER the last character; so that the length of the value String is valueEnd - valueStart
Returns:
Null, if the passed value is fine as is; or a String, if it needs to be replaced. In latter case, caller will replace the value before passing it to other validators. Also, if the attribute value is accessible via caller (as is the case for stream readers), caller should return this value, instead of the original one.
Throws:
XMLValidationException

validateElementAndAttributes

public int validateElementAndAttributes()
                                 throws XMLValidationException
Description copied from class: XMLValidator
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.

Specified by:
validateElementAndAttributes in class DTDValidatorBase
Returns:
One of CONTENT_ALLOW_ constants, to indicate what kind of textual content is allowed at the scope returned to after the element has closed.
Throws:
XMLValidationException

validateElementEnd

public int validateElementEnd(java.lang.String localName,
                              java.lang.String uri,
                              java.lang.String prefix)
                       throws XMLValidationException
Description copied from class: XMLValidator
Method called right after encountering an element close tag.

Specified by:
validateElementEnd in class DTDValidatorBase
Returns:
Validation state that should be effective for the parent element state
Throws:
XMLValidationException

validationCompleted

public void validationCompleted(boolean eod)
                         throws XMLValidationException
Description copied from class: XMLValidator
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).

Specified by:
validationCompleted in class DTDValidatorBase
Parameters:
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).
Throws:
XMLValidationException

getIdMap

protected com.ctc.wstx.dtd.ElementIdMap getIdMap()
Specified by:
getIdMap in class DTDValidatorBase
