Method Detail

startContentModel

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

Returns:

Start state of the content model

oneTransition

Object oneTransition(QName elementName,
                   int[] state,
                   SubstitutionGroupHandler subGroupHandler)

The method corresponds to one transaction in the content model.

Parameters:

elementName -

state - Current state

Returns:

element decl or wildcard decl that corresponds to the element from the Schema grammar

endContentModel

boolean endContentModel(int[] state)

The method indicates the end of list of children

Parameters:

state - Current state of the content model

Returns:

true if the last state was a valid final state

checkUniqueParticleAttribution

boolean checkUniqueParticleAttribution(SubstitutionGroupHandler subGroupHandler)
                                       throws XMLSchemaException

check whether this content violates UPA constraint.

Parameters:

subGroupHandler - the substitution group handler

Returns:

true if this content model contains other or list wildcard

Throws:

XMLSchemaException

whatCanGoHere

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.

Parameters:

state - the current state

Returns:

a Vector whose entries are instances of either XSWildcardDecl or XSElementDecl.

checkMinMaxBounds

ArrayList 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. Returns null if validation of bounds is successful. Returns a list of strings with error info if not. Even entries in list returned are error codes (used to look up properties) and odd entries are parameters to be passed when formatting error message. Each parameter is associated with the error code that preceeds it in the list.
