startContentModel
public int[] startContentModel()This methods to be called on entering a first element whose type has this content model. It will return the initial state of the content model- Specified by:
startContentModel
in interfaceXSCMValidator
- Returns:
- Start state of the content model
-
oneTransition
public Object oneTransition(org.apache.xerces.xni.QName elementName, int[] currentState, SubstitutionGroupHandler subGroupHandler) The method corresponds to one transition in the content model.- Specified by:
oneTransition
in interfaceXSCMValidator
- Parameters:
elementName
-currentState
- Current state- Returns:
- an element decl object
-
endContentModel
public boolean endContentModel(int[] currentState) The method indicates the end of list of children- Specified by:
endContentModel
in interfaceXSCMValidator
- Parameters:
currentState
- Current state of the content model- Returns:
- true if the last state was a valid final state
-
checkUniqueParticleAttribution
public boolean checkUniqueParticleAttribution(SubstitutionGroupHandler subGroupHandler) throws XMLSchemaException check whether this content violates UPA constraint.- Specified by:
checkUniqueParticleAttribution
in interfaceXSCMValidator
- Parameters:
subGroupHandler
- the substitution group handler- Returns:
- true if this content model contains other or list wildcard
- Throws:
XMLSchemaException
-
whatCanGoHere
Check which elements are valid to appear at this point. This method also works if the state is in error, in which case it returns what should have been seen.- Specified by:
whatCanGoHere
in interfaceXSCMValidator
- Parameters:
state
- the current state- Returns:
- a Vector whose entries are instances of either XSWildcardDecl or XSElementDecl.
-
occurenceInfo
public int[] occurenceInfo(int[] state) Description copied from interface:XSCMValidator
Returns an array containing information about the current repeating term or
null
if no occurrence counting was being performed at the current state.If an array is returned it will have a length == 4 and will contain:
- a[0] :: min occurs
- a[1] :: max occurs
- a[2] :: current value of the counter
- a[3] :: identifier for the repeating term
- Specified by:
occurenceInfo
in interfaceXSCMValidator
- Parameters:
state
- the current state- Returns:
- an array containing information about the current repeating term
-
getTermName
Description copied from interface:XSCMValidator
Returns the name of the term (element or wildcard) for the given identifier.- Specified by:
getTermName
in interfaceXSCMValidator
- Parameters:
termId
- identifier for the element declaration or wildcard- Returns:
- the name of the element declaration or wildcard
-
isCompactedForUPA
public boolean isCompactedForUPA()Description copied from interface:XSCMValidator
Checks if this content model has had its min/maxOccurs values reduced for purposes of speeding up UPA. If so, this content model should not be used for any purpose other than checking unique particle attribution- Specified by:
isCompactedForUPA
in interfaceXSCMValidator
- Returns:
- a boolean that says whether this content has been compacted for UPA
-
