Method Summary | |
---|---|
int | validate(QName[] children, int offset, int length)
Check that the specified content is valid according to this
content model. |
Parameters: children The list of allowed children. type The list of the types of the children. offset The start offset position in the children. length The child count. ordered True if content must be ordered.
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 within
the StringPool
of the child element name. An index
of -1 is used to indicate an occurrence of non-whitespace character
data. offset Offset into the array where the children starts. length The number of entries in the children
array.
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.
