java.lang.Object | +--org.apache.xerces.validators.common.DFAContentModel
DFAContentModel is the derivative of ContentModel that does all of the non-trivial element content validation. This class does the conversion from the regular expression to the DFA that it then uses in its validation algorithm.
| Constructor Summary | |
|---|---|
DFAContentModel(CMNode syntaxTree,
int leafCount)
Constructs a DFA content model. |
|
DFAContentModel(CMNode syntaxTree,
int leafCount,
boolean dtd,
boolean mixed)
Constructs a DFA content model. |

|

isFinalState(int state)
check whether the given state is one of the final states |
int |
oneTransition(QName curElem,
int[] stateStack,
int curPos)
one transition only |
void |
setSubstitutionGroupComparator(SubstitutionGroupComparator comparator)
The setter method to pass in the SubstitutionGroupComparator. |
int |
validateContent(QName[] children,
int offset,
int length)
Check that the specified content is valid according to this content model. |
int |
validateContentSpecial(QName[] children,
int offset,
int length)
This method is different from "validateContent" in that it will try to use the SubstitutionGroupComparator to match children against the content model. |
int |
whatCanGoHere(boolean fullyValid,
InsertableElementsInfo info)
Returns information about which elements can be placed at a particular point in the passed element's content model. |

A value of -1 in the children array indicates a PCDATA node. All other indexes will be positive and represent child elements. The count can be zero, since some elements have the EMPTY content model and that must be confirmed.

the StringPool of the child element name. An index
of -1 is used to indicate an occurrence of non-whitespace character

throws CMException
Note that the incoming content model to test must be valid at least up to the insertion point. If not, then -1 will be returned and the info object will not have been filled in.
If, on return, the info.isValidEOC flag is set, then the 'insert after' element is a valid end of content. In other words, nothing needs to be inserted after it to make the parent element's content model valid.
whatCanGoHere in interface XMLContentModelfullyValid - Only return elements that can be inserted and still
maintain the validity of subsequent elements past the
insertion point (if any). If the insertion point is at
the end, and this is true, then only elements that can
be legal final states will be returned.info - An object that contains the required input data for the method,
and which will contain the output information if successful.InsertableElementsInfopublic ContentLeafNameTypeVector getContentLeafNameTypeVector()
