public List<String> checkMinMaxBounds()

Implements com.sun.org.apache.xerces.internal.impl.xs.models.XSCMValidator.checkMinMaxBounds.

Doc from com.sun.org.apache.xerces.internal.impl.xs.models.XSCMValidator.checkMinMaxBounds.

Used by constant space algorithm for a{n,m} for n > 1 and m <= unbounded. Called by a validator if validation of countent model succeeds after subsuming a{n,m} to a* (or a+) to check the n and m bounds.

checkUniqueParticleAttributionback to summary
public boolean checkUniqueParticleAttribution(SubstitutionGroupHandler subGroupHandler) throws XMLSchemaException

Implements com.sun.org.apache.xerces.internal.impl.xs.models.XSCMValidator.checkUniqueParticleAttribution.

check whether this content violates UPA constraint.

Parameters
subGroupHandler:SubstitutionGroupHandler

the substitution group handler

Returns:boolean

true if this content model contains other or list wildcard

endContentModelback to summary
public boolean endContentModel(int[] currentState)

Implements com.sun.org.apache.xerces.internal.impl.xs.models.XSCMValidator.endContentModel.

The method indicates the end of list of children

Parameters
currentState:int[]

Current state of the content model

Returns:boolean

true if the last state was a valid final state

public String getTermName(int termId)

Implements com.sun.org.apache.xerces.internal.impl.xs.models.XSCMValidator.getTermName.

Doc from com.sun.org.apache.xerces.internal.impl.xs.models.XSCMValidator.getTermName.

Returns the name of the term (element or wildcard) for the given identifier.

public boolean isCompactedForUPA()

Implements com.sun.org.apache.xerces.internal.impl.xs.models.XSCMValidator.isCompactedForUPA.

Doc from com.sun.org.apache.xerces.internal.impl.xs.models.XSCMValidator.isCompactedForUPA.

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

Implements com.sun.org.apache.xerces.internal.impl.xs.models.XSCMValidator.occurenceInfo.

Doc from com.sun.org.apache.xerces.internal.impl.xs.models.XSCMValidator.occurenceInfo.

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

whatCanGoHereback to summary
public List<Object> whatCanGoHere(int[] state)

Implements com.sun.org.apache.xerces.internal.impl.xs.models.XSCMValidator.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.
