Field Detail

DEBUG_IDENTITY_CONSTRAINTS

protected static final boolean DEBUG_IDENTITY_CONSTRAINTS

Compile to true to debug identity constraints.

DEBUG_VALUE_STORES

protected static final boolean DEBUG_VALUE_STORES

Compile to true to debug value stores.

fMatcherStack

protected XMLValidator.XPathMatcherStack fMatcherStack

Stack of active XPath matchers for identity constraints. All active XPath matchers are notified of startElement, characters and endElement callbacks in order to perform their matches.

For each element with identity constraints, the selector of each identity constraint is activated. When the selector matches its XPath, then all the fields of the identity constraint are activated.

Note: Once the activation scope is left, the XPath matchers are automatically removed from the stack of active matchers and no longer receive callbacks.

fValueStoreCache

protected XMLValidator.ValueStoreCache fValueStoreCache

Cache of value stores for identity constraint fields.

fSGComparator

protected SubstitutionGroupComparator fSGComparator

UPACheckedGrammarURIs

protected java.util.Hashtable UPACheckedGrammarURIs

fgNullObject

protected static java.lang.Object fgNullObject

Constructor Detail

XMLValidator

public XMLValidator(StringPool stringPool,

whatCanGoHere

protected int whatCanGoHere(int elementIndex,
                            boolean fullyValid,
                            InsertableElementsInfo info)
                     throws java.lang.Exception

Returns information about which elements can be placed at a particular point in the passed element's content model.

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' elemement is a valid end of content, i.e. nothing needs to be inserted after it to make the parent element's content model valid.

Parameters:

elementIndex - The index within the ElementDeclPool of the element which is being querying.

fullyValid - 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.

Returns:

The value -1 if fully valid, else the 0 based index of the child that first failed before the insertion point. If the value returned is equal to the number of children, then the specified children are valid but additional content is required to reach a valid ending state.

Throws:

java.lang.Exception - Thrown on error.
