Constructor Detail

### XSAllCM

    public XSAllCM(boolean hasOptionalContent,
                   int size)

Method Detail

### addElement

    public void addElement(XSElementDecl element,
                           boolean isOptional)

### 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 transition in the content model.

  Specified by:
    `oneTransition` in interface `XSCMValidator`
  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 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
  Throws:
    `XMLSchemaException`

### 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`
  Returns:
    a boolean that says whether this content has been compacted for UPA
