This abstract class provides the interface for all validators.
This is the simple amount of API that all validators must honor, in order for the scanner to use them to do validation. All validators will actually contain much more functionality than is accessible via this common API, but that functionality requires that you know what type of validator you are dealing with.
Basically, at this level, the primary concern is to be able to query core information about elements and attributes. Adding decls to the validator requires that you go through the derived interface because they all have their own decl types. At this level, we can return information via the base decl classes, from which each validator derives its own decl classes.
The derived class should look up its declaration of the passed element from its element pool.
It should then use the content model description contained in that element declaration to validate that the passed list of child elements are valid for that content model. The count can be zero, indicating no child elements.
Note that whitespace and text content are not validated here. Those are handled by the scanner. So only element ids are provided here.
- Parameters
-
elemDecl | The element whose content is to be checked. |
children | An array of element QName which represent the elements found within the parent element, i.e. the content to be validated. |
childCount | The number of elements in the childIds array. It can be zero if the element had none. |
indexFailingChild | On return, it will contain the index of the children failing validation, if the retun value is false |
This call is a convenience by which validators can emit errors.
Most of the grunt work of loading the text, getting the current source location, ect... is handled here.
If the loaded text has replacement parameters, then text strings can be passed. These will be used to replace the tokens {0}, {1}, {2}, and {3} in the order passed. So text1 will replace {0}, text2 will replace {1}, and so forth.
textX Up to four replacement parameters. They can be provided as either XMLCh strings, or local code page strings which will be transcoded internally.
- Parameters
-
toEmit | The error code to emit. it must be one of the defined validator error codes. |

The derived class should apply any rules to the passed attribute value that are above and beyond those defined by XML 1.0.
The scanner itself will impose XML 1.0 rules, based on the type of the attribute. This will generally be used to check things such as range checks and other datatype related validation.
If the value breaks any rules as defined by the derived class, it should just issue errors as usual.
