- All Implemented Interfaces:
- XSCMValidator
- public class XSEmptyCM
- extends java.lang.Object
- implements XSCMValidator
XSEmptyCM is a derivative of the abstract content model base class that
handles a content model with no children (elements).
This model validated on the way in.

XSEmptyCM
public XSEmptyCM()
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 interface XSCMValidator
- Returns:
- Start state of the content model
oneTransition
public java.lang.Object oneTransition(org.apache.xerces.xni.QName elementName,
int[] currentState,
SubstitutionGroupHandler subGroupHandler)
- The method corresponds to one transaction in the content model.
- Specified by:
oneTransition
in interface XSCMValidator
- Parameters:
elementName
- the qualified name of the elementcurrentState
- Current statesubGroupHandler
- the substitution group handler- Returns:
- element index corresponding to the element from the Schema grammar
endContentModel
public boolean endContentModel(int[] currentState)
- The method indicates the end of list of children
- Specified by:
endContentModel
in interface XSCMValidator
- 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 interface XSCMValidator
- Parameters:
subGroupHandler
- the substitution group handler- Returns:
- true if this content model contains other or list wildcard
whatCanGoHere
public java.util.Vector whatCanGoHere(int[] state)
- 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 interface XSCMValidator
- Parameters:
state
- the current state- Returns:
- a Vector whose entries are instances of
either XSWildcardDecl or XSElementDecl.
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 interface XSCMValidator
- Following copied from interface:
org.apache.xerces.impl.xs.models.XSCMValidator
- Returns:
- a boolean that says whether this content has been compacted for UPA
