Methods

Modifier and Type	Method and Description
void	append(Item item, int locationId, int copyNamespaces) Append an arbitrary item (node or atomic value) to the output

protected void	reportValidationError(ValidationException err, boolean issueComment, int locationId) Report a validation error
void	setConstraintChecker(ConstraintChecker checker) Set the constraint checker used in this pipeline
void	setStartTagBuffer(StartTagBufferEE startTag) Set the StartTagBuffer, which buffers attributes on the element start tag, and also acts as the namespaceResolver to be used for resolving QName-valued attributes

Method Detail

getValidationContext

public ValidationContext getValidationContext()

Get the validation context for this validation episode

Returns:

the validation context

setValidationContext

public void setValidationContext(ValidationContext validationContext)

Set the validation context for this validation episode

Parameters:

validationContext -

setConstraintChecker

public void setConstraintChecker(ConstraintChecker checker)

Set the constraint checker used in this pipeline

Parameters:

checker - the constraint checker

getConstraintChecker

protected ConstraintChecker getConstraintChecker()

Get the constraint checker used in this pipeline

Returns:

the constraint checker

setStartTagBuffer

public void setStartTagBuffer(StartTagBufferEE startTag)

Set the StartTagBuffer, which buffers attributes on the element start tag, and also acts as the namespaceResolver to be used for resolving QName-valued attributes

Parameters:

startTag - the namespace resolver

getStartTagBuffer

public StartTagBufferEE getStartTagBuffer()

Get the startTagBuffer

Returns:

the startTagBuffer

usesTypeAnnotations

public boolean usesTypeAnnotations()

Ask whether this Receiver (or the downstream pipeline) makes any use of the type annotations supplied on element and attribute events

Specified by:

usesTypeAnnotations in interface Receiver

Overrides:

usesTypeAnnotations in class ProxyReceiver

Returns:

true if the Receiver makes any use of this information. If false, the caller may supply untyped nodes instead of supplying the type annotation. Validation filters overwrite any type annotations arriving in the input event stream, so this instance of the method returns false.

append

public void append(Item item,
          int locationId,
          int copyNamespaces)
            throws XPathException

Description copied from class: ProxyReceiver

Append an arbitrary item (node or atomic value) to the output

Overrides:

append in class ProxyReceiver

Parameters:

item - the item to be appended

locationId - the location of the calling instruction, for diagnostics

copyNamespaces - if the item is an element node, this indicates whether its namespaces need to be copied. Values are NodeInfo.ALL_NAMESPACES, NodeInfo.LOCAL_NAMESPACES, NodeInfo.NO_NAMESPACES

Throws:

XPathException - if the operation fails

reportValidationError

protected void reportValidationError(ValidationException err,
                         boolean issueComment,
                         int locationId)
                              throws XPathException

Report a validation error

Parameters:

err - The validation exception

issueComment - true if the validation error message is to be written as an XML comment to the result document

locationId - identifies the location in the source document or stylesheet/query where the validation error was detected

Throws:

XPathException - if reporting the error fails

reportIfInvalid

protected void reportIfInvalid()
                        throws ValidationException

Throws:

ValidationException
