Detailed Description

A SchemaValidator represents a factory for validating instance documents against a schema.

Constructor & Destructor Documentation

SchemaValidator() [1/3]

SchemaValidator::SchemaValidator

(

)

Default constructor.

Creates Schema Validator

Exceptions

SaxonApiException

SchemaValidator() [2/3]

SchemaValidator::SchemaValidator	(	SaxonProcessor *	proc,
		std::string	cwd = ""
	)

A constructor with a SaxonProcessor.

The supplied processor should have license flag set to true for the Schema Validator to operate.

Parameters

proc	- the SaxonProcessor
cwd	- set the current working directory

Exceptions

SaxonApiException

SchemaValidator() [3/3]

SchemaValidator::SchemaValidator

(

const SchemaValidator &

other

)

Copy constructor.

Creates Schema Validator

~SchemaValidator()

SchemaValidator::~SchemaValidator

(

)

Destructor method. At the end of the program call the release() method to clear the JVM.

Member Function Documentation

checkException()

const char * SchemaValidator::checkException

(

)

Check for exception thrown.

Returns

char*. Returns the main exception message if thrown otherwise return nullptr

clearParameters()

void SchemaValidator::clearParameters

(

bool

deleteValues = false

)

Clear parameter values set.

Default behaviour (false) is to leave XdmValues in memory. Individual pointers to XdmValue objects have to be deleted in the calling program.

Parameters

deleteValues

- if true then XdmValues are deleted

exceptionOccurred()

bool SchemaValidator::exceptionOccurred

(

)

Checks for pending exceptions without creating a local reference to the exception object

Returns

bool - true when there is a pending exception; otherwise return false

exportSchema()

void SchemaValidator::exportSchema

(

const char *

fileName

)

Export a precompiled Schema Component Model containing all the components (except built-in components) that have been loaded by using the register methods.

Parameters

fileName

- The file name where the exported schema will be stored

Exceptions

SaxonApiException

getErrorCode()

const char * SchemaValidator::getErrorCode

(

)

Get error code if an error is reported.

Validation error are reported as exceptions. All errors can be retrieved.

Returns

char* - The error code of the exception.

getErrorMessage()

const char * SchemaValidator::getErrorMessage

(

)

Get number of errors during validation of the source against the schema.

Returns

int - Count of the exceptions reported during validation Get the error message if there are any validation errors May have a number of validation errors reported against it the source.

char* - The message of the exception thrown

getValidationReport()

XdmNode * SchemaValidator::getValidationReport

(

)

Get the Validation report.

The validation-report option must have been set to true in the properties to use this feature.

Returns

XdmNode - Pointer to XdmNode. Return nullptr if validation reporting feature has not been enabled

Exceptions

SaxonApiException

operator=()

SchemaValidator & SchemaValidator::operator=

(

const SchemaValidator &

other

)

The copy assignment= operator.

Create a copy of the SchemaValidator.

Parameters

other

- SchemaValidator object

registerSchemaFromFile()

void SchemaValidator::registerSchemaFromFile

(

const char *

xsd

)

Register the schema from file name.

The schema components derived from this schema document are added to the cache of schema components maintained by this SchemaManager

Parameters

xsd	- File name of the schema relative to the cwd or full path if cwd is null. The document may be either a schema document in source XSD format, or a compiled schema in Saxon-defined SCM format (as produced using the method exportSchema)

Exceptions

SaxonApiException

registerSchemaFromNode()

void SchemaValidator::registerSchemaFromNode

(

XdmNode *

node

)

Register the schema supplied as an XDM Node Object.

Parameters

schemaStr

- The schema document supplied as an XdmNode object

Exceptions

SaxonApiException

registerSchemaFromString()

void SchemaValidator::registerSchemaFromString	(	const char *	schemaStr,
		const char *	systemID = nullptr
	)

Register the schema supplied as a string.

Parameters

schemaStr

- The schema document supplied as a string

Exceptions

SaxonApiException

removeParameter()

bool SchemaValidator::removeParameter

(

const char *

name

)

Remove a parameter (name, value) pair.

Parameters

name	of the parameter

Returns

bool - outcome of the removal

setcwd()

void SchemaValidator::setcwd

(

const char *

cwd

)

Set the Current working Directory.

Set the current working directory for the Schema Validator

Parameters

cwd	- Supplied working directory which replaces any set cwd. Ignore if cwd is NULL.

setLax()

void SchemaValidator::setLax

(

bool

l

)

The validation mode may be either strict or lax.

The default is strict; this method may be called to indicate that lax validation is required. With strict validation, validation fails if no element declaration can be located for the outermost element. With lax validation, the absence of an element declaration results in the content being considered valid.

Parameters

l	- true if validation is to be lax, false if it is to be strict

setOutputFile()

void SchemaValidator::setOutputFile

(

const char *

outputFile

)

Set the name of the output file that will be used by the validator.

Parameters

outputFile

the output file name for later use

setParameter()

void SchemaValidator::setParameter	(	const char *	name,
		XdmValue *	value
	)

Set a parameter value used in the validator.

Parameters

name	of the parameter, as a string. For namespaced parameter use the JAXP solution i.e. "{uri}name"
value	of the query parameter, or nullptr to clear a previously set value

setProperty()

void SchemaValidator::setProperty	(	const char *	name,
		const char *	value
	)

Set a property.

Parameters

name	of the property
value	of the property

setSourceNode()

void SchemaValidator::setSourceNode

(

XdmNode *

source

)

Set the source node for validation.

Parameters

source

- The source document supplied as an XdmNode, which will be used to validate against the schema using the validate methods. The deletion of allocated memory associated with the source node is the document is the responsbility of the caller.

validate()

void SchemaValidator::validate

(

const char *

sourceFile = nullptr

)

Validate an instance document by a registered schema.

Parameters

sourceFile

Name of the file to be validated. Allow nullptr when source document is supplied with other method

Exceptions

SaxonApiException

validateToNode()

XdmNode * SchemaValidator::validateToNode

(

const char *

sourceFile = nullptr

)

Validate an instance document supplied as a Source object.

Parameters

sourceFile

The name of the file to be validated. Default is nullptr

Returns

XdmNode - the validated document returned to the calling program

Exceptions

SaxonApiException
