ContentModelAcceptor
protected ContentModelAcceptor(REDocumentDeclaration docDecl,
Expression exp,
boolean ignoreUndeclaredAttributes)
stepForward
public boolean stepForward(Acceptor child,
StringRef errRef)
- Description copied from interface:
Acceptor
- eats a child element
A child acceptor created by the createChildAcceptor
method
will be ultimately consumed by the parent through this method.
It is the caller's responsibility to make sure that child acceptor
is in the accept state. If it's not, that indicates that some required
elements are missing (in other words, contents are not allowed to end here).
It is the callee's responsibility to recover from error of
unsatisified child acceptor. That is, even if the caller finds that
there are missing elements, it is possible to call this method
as if there was no such error.
- Returns:
- false
if an error happens. For example, if the implementation passes
an acceptor which is NOT a child of this acceptor, then
the callee can return false.
createAcceptor
protected Acceptor createAcceptor(Expression combined,
Expression continuation,
ElementExp[] primitives,
int numPrimitives)
- creates actual Acceptor object from the computed result.
- Specified by:
createAcceptor
in class ExpressionAcceptor
getOwnerType
public Object getOwnerType()
- Description copied from interface:
Acceptor
- gets the "type" object for which this acceptor is working.
This method is used for type assignment. Actual Java type of
return value depends on the implementation.
- Returns:
- null
the callee should return null when it doesn't support
type-assignment feature, or type-assignment is impossible
for this acceptor (for example by ambiguous grammar).
