 org.apache.xerces.impl.dtd.models.MixedContentModel
| MixedContentModel | | public class MixedContentModel implements ContentModelValidator(Code) | | MixedContentModel is a derivative of the abstract content model base
class that handles the special case of mixed model elements. If an element
is mixed model, it has PCDATA as its first possible content, followed
by an alternation of the possible children. The children cannot have any
numeration or order, so it must look like this:
<!ELEMENT Foo ((#PCDATA|a|b|c|)*)>
So, all we have to do is to keep an array of the possible children and
validate by just looking up each child being validated by looking it up
in the list.

| Constructor Summary | |
| public | MixedContentModel(QName[] children, int[] type, int offset, int length, boolean ordered)
Constructs a mixed content model. |
| Method Summary | |
| public int | validate(QName[] children, int offset, int length)
Check that the specified content is valid according to this
content model. |
| MixedContentModel | | public MixedContentModel(QName[] children, int[] type, int offset, int length, boolean ordered)(Code) | | Constructs a mixed content model.
Parameters:
children - The list of allowed children.
Parameters:
type - The list of the types of the children.
Parameters:
offset - The start offset position in the children.
Parameters:
length - The child count.
Parameters:
ordered - True if content must be ordered. |
| validate | | public int validate(QName[] children, int offset, int length)(Code) | | 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.
Parameters:
children - The children of this element. Each integer is an index withinthe StringPool of the child element name. An indexof -1 is used to indicate an occurrence of non-whitespace characterdata.
Parameters:
offset - Offset into the array where the children starts.
Parameters:
length - The number of entries in the children array. The value -1 if fully valid, else the 0 based index of the childthat first failed. If the value returned is equal to the numberof children, then the specified children are valid but additionalcontent is required to reach a valid ending state. |
