Class | Description |
---|---|
AllElementValidator |
This class is validator used to check the content of an element whose complex type
uses the "xs:all" construction in XML Schema.
|
AnyTypeValidator |
Validator to validate an element against the class xs:anyType
|
AssertionTreeBuilder |
This class sits in the validation pipeline, ready (when requested) to build subtrees of the validated
document for use in testing assertions against complex types.
|
AttributeValidator |
This class is an abstract superclass for all the receivers that do element content
validation.
|
CatchingReceiver |
This class catches all errors thrown by a Receiver pipeline, and reports them to a specified
ErrorListener; after an error has occurred, all further events are ignored.
|
Checker |
A Checker is a Receiver used to check the content of elements and attributes, especially those
that participate in uniqueness, key, and keyref constraints
|
CompactStringValue |
A compact representation of an atomic xs:string value used in saved tables for key and keyref constraints,
designed to economize on space.
|
ComplexContentValidator |
This class is a filter that is used to validate the content of an element with a
complex type.
|
ConstraintChecker |
This class handles the checking of Schema-defined unique, key, and keyref
constraints.
|
ContentValidator |
This class is an abstract superclass for all the validators.
|
EmptyContentValidator |
This class is a filter that is used to validate that an element has empty content.
|
EntityValidator |
This class validates that elements and attributes of type ENTITY or ENTITIES have values are
declared in the DOCTYPE declaration of the instance document as unparsed entities.
|
FieldChecker |
A FieldChecker is instantiated when a field in an identity constraint is matched; it receives
notification of all events until the end of the element (or attribute) that matched the selector.
|
FieldWatch |
A FieldWatch is a class that is looking for nodes that match a field
selector within a uniqueness or key constraint.
|
IdValidator |
This class validates that ID elements and attributes have unique values and that
IDREF and IDREFS elements and attributes refer to an ID in the same document.
|
InSituValidator |
This class performs in-situ validation of a tree represented in memory as a NodeInfo
object.
|
InvalidityReportGeneratorEE |
This class
InvalidityReportGenerator extends the standard error handler for errors found during validation
of an instance document against a schema, used if user specifies -report option on validate. |
KeySelectorWatch |
This class watches the selector for a key or unique constraint
|
LaxValidator |
This class performs lax validation on an element.
|
RefSelectorWatch |
This class watches the selector for a keyref constraint
|
SchemaAttributeTest |
A NodeTest of the form schema-attribute(attribute-name)
|
SchemaElementTest |
A NodeTest of the form schema-element(element-name)
|
SelectorWatch |
A Watch represents a class that is interested in looking at nodes for the purpose
of evaluating uniqueness and key constraints.
|
SimpleContentValidator |
This class is a filter that is used to validate that an element has simple content
conforming to a given simple type.
|
SkipValidator |
This class is a filter that passes all Receiver events through unchanged,
except that it removes all type annotations from element and attribute nodes.
|
StartTagBufferEE |
This class handles attribute inheritance.
|
StatisticsReporter |
Generates statistics relating to a validation episode
|
ValidatingFilter |
This class is used for a filter on the validation pipeline.
|
ValidationContext |
This class defines information about a validation episode
|
ValidationStack |
This class manages the receivers that do element content
validation.
|
XSIAttributeHandler |
This class processes attributes such as xsi:schemaLocation and xsi:type.
|
The validation package contains classes used to validate document instances against a schema.
This validation is all performed "on-the-fly", by a collection of classes that implement Saxon's (SAX-like) Receiver interface, which is notified of start/end element events, attributes, and text nodes, as they occur. A pipeline of such classes is used both while processing input documents and while writing output documents, and in both cases, validation classes can be added to the pipeline.
Local validation of elements is controlled using the ValidationStack class, which manages a stack of validators for each element that is currently open. The most interesting of these is the ComplexContentValidator, which makes use of a finite state machine created by compiling a ComplexType in the schema. The finite state machine is represented by the AutomatonState object corresponding to the initial (entry) state of the machine.
Global validation of uniqueness and referential constraints is controlled using the ConstraintChecker class. The maintains a set of Watch classes that are interested in elements matching particular (restricted) XPath expressions. The restricted XPath expression used in XML Schema (which is similar to, but not identical to, an XPath pattern) is represented by a Selection object. Implementations of the Watch class are used to handle the different kinds of constraint that a schema can specify.
None of the classes in this package will normally be used directly by user applications.
