ElementDeclPool elementDeclPool,
StringPool stringPool,
int childIndex)
validateContent
public int validateContent(int childCount,
int[] children)
throws java.lang.Exception
- Check that the specified content is valid according to this
content model. This method can also be called to do 'what if'
testing of content models just to see if they would be valid.
A value of -1 in the children array indicates a PCDATA node. All other
indexes will be positive and represent child elements. The count can be
zero, since some elements have the EMPTY content model and that must be
confirmed.
- Specified by:
- validateContent in interface XMLContentModel
- Parameters:
childCount
- The number of entries in the children
array.children
- The children of this element. Each integer is an index within
the StringPool
of the child element name. An index
of -1 is used to indicate an occurrence of non-whitespace character
data.- Returns:
- The value -1 if fully valid, else the 0 based index of the child
that first failed. If the value returned is equal to the number
of children, then the specified children are valid but additional
content is required to reach a valid ending state.
- Throws:
- java.lang.Exception - Thrown on error.
whatCanGoHere
public int whatCanGoHere(boolean fullyValid,
InsertableElementsInfo info)
throws java.lang.Exception
- Returns information about which elements can be placed at a particular point
in the passed element's content model.
Note that the incoming content model to test must be valid at least up to
the insertion point. If not, then -1 will be returned and the info object
will not have been filled in.
If, on return, the info.isValidEOC flag is set, then the 'insert after'
element is a valid end of content. In other words, nothing needs to be
inserted after it to make the parent element's content model valid.
- Specified by:
- whatCanGoHere in interface XMLContentModel
- Parameters:
fullyValid
- Only return elements that can be inserted and still
maintain the validity of subsequent elements past the
insertion point (if any). If the insertion point is at
the end, and this is true, then only elements that can
be legal final states will be returned.info
- An object that contains the required input data for the method,
and which will contain the output information if successful.- Returns:
- The value -1 if fully valid, else the 0 based index of the child
that first failed before the insertion point. If the value
returned is equal to the number of children, then the specified
children are valid but additional content is required to reach a
valid ending state.
