Class RelaxNGDataModel

java.lang.Object

com.adobe.xmp.schema.rng.parser.RelaxNGDataModel

public class RelaxNGDataModel
extends Object

This class models a RelaxNG schema's data model as described by RelaxNG spec. This model can describe either a XMP packet composed of multiple XMP schemas or a single XMP schema. This class provides functionality to traverse the RelaxNG data model to construct the XMP schemas represeted by the model.

Method Detail

newInstance

public static RelaxNGDataModel newInstance(URI rngFile,
                                           EntityResolver er)
                                    throws RNGParseException,
                                           RNGInvalidSchemaException,
                                           MalformedURLException,
                                           IOException

Construct a RelaxNGDataModel which models the input RelaxNG schema.

Parameters:

rngFile - File representing the RelaxNG schema

er - A RelaxNG schema references and includes multiple other files. This enity resolver should define how these dependecies should be located by RelaxNG schema parser.

Returns:

RelaxNGDataModel

Throws:

RNGParseException - If a exception occured while

RNGInvalidSchemaException - If the input RelaxNg schema voilates RNG spec

IOException - if rngFile cannot be resolved or loaded

MalformedURLException - If URI is malformed

newInstance

public static RelaxNGDataModel newInstance(URI rngFile,
                                           EntityResolver er,
                                           ErrorHandler eh)
                                    throws RNGInvalidSchemaException,
                                           MalformedURLException,
                                           IOException

Construct a RelaxNGDataModel which models the input RelaxNG schema.

Parameters:

rngFile - File representing the RelaxNG schema

er - A RelaxNG schema references and includes multiple other files. This entity resolver should define how these dependencies should be located by RelaxNG schema parser.

eh - ErrorHandler to handle error call backs generated by RelaxNG schema parser

Returns:

RelaxNGDataModel

Throws:

RNGInvalidSchemaException - If the input RelaxNg schema violates RNG spec

MalformedURLException - If URI is malformed

IOException - if rngFile cannot be resolved or loaded

newInstance

public static RelaxNGDataModel newInstance(InputSource is,
                                           EntityResolver er)
                                    throws RNGInvalidSchemaException

Construct a RelaxNGDataModel which models the input RelaxNG schema.

Parameters:

is - InputSource representing the RelaxNG schema

er - A RelaxNG schema references and includes multiple other files. This entity resolver should define how these dependencies should be located by RelaxNG schema parser.

Returns:

RelaxNGDataModel

Throws:

RNGInvalidSchemaException - If the input RelaxNg schema violates RNG spec

newInstance

public static RelaxNGDataModel newInstance(InputSource is,
                                           EntityResolver er,
                                           ErrorHandler eh)
                                    throws RNGInvalidSchemaException

Construct a RelaxNGDataModel which models the input RelaxNG schema.

Parameters:

is - InputSource representing the RelaxNG schema

er - A RelaxNG schema references and includes multiple other files. This enity resolver should define how these dependecies should be located by RelaxNG schema parser.

eh - ErrorHandler to handle error call backs generated by RelaxNG schema parser

Returns:

RelaxNGDataModel

constructXMPSchema

public SchemaDescription constructXMPSchema(SchemaGenerationHandler handler)
                                     throws RNGParseException,
                                            XMPSchemaException

Gets the schema which is represented by this RelaxNGDataModel

Parameters:

handler - This handler provides notifications for various events such as start, end of parsing a ref, start of property parsing, errors recieved while parsing property. This should not be null.

Returns:

First XMP schema from the list of XMP schemas represented by this RelaxNG schema

Throws:

RNGParseException - If a problem occured while traversing RelaxNGDataModel to form a SchemaDescription object. This can happen if the input Relax NG schema does not correctly model a XMP schema.

XMPSchemaException - Exception thrown for SchemaDescription is propogated
