Interface BinXMLMetadataProvider

All Known Subinterfaces:

DBBinXMLMetadataProvider

public interface BinXMLMetadataProvider

This interface defines APIs for users to plug in a metadata repository used for encoding and decoding. A database implementation of this API is provided , see DBBinXMLMetadataProvider interface.

Method Summary

java.io.Reader	getCompiledSchema(BinXMLVocabId schemaId) Fetches the schema as a binary stream from the metadata repository based on the vocabulary id.
java.io.Reader	getCompiledSchema(java.lang.String schemaURL) Fetches the schema as a binary stream from the metadata repository based on the schema URL.
BinXMLStream	getDTD(BinXMLVocabId dtdId) Fetches the DTD as a binary stream from the metadata repository based on the vocabulary id.
BinXMLStream	getDTD(java.lang.String dtdURL) Fetches the DTD as a binary stream from the metadata repository based on the DTD URL.
BinXMLStream	getTokenSet(long tokenId)
BinXMLStream	getTokenSet(long tokenId, boolean isNS) Fetches the Token Set as a binary stream in the metadata repository based on the namespace of the input token Id.
BinXMLStream	getTokenSet(java.lang.String namespaceURL, boolean isAttr) Fetches the Token Set as a binary stream in the metadata repository based on the namespace URL.
boolean	isSchemaAnnotationAvailable() Specifies whether the repository performs schema annotations or not.
BinXMLVocabId	saveCompiledSchema(java.lang.String schemaURL) Saves the annotated schema as a binary stream in the metadata repository.
BinXMLVocabId	saveDTD(java.lang.String dtdURL) Saves the DTD as a binary stream in the metadata repository.
BinXMLVocabId	saveSchema(java.lang.String schemaURL) The repository accepts a non-annotated schema, annotates it and saves it as a binary stream in the metadata repository.
BinXMLVocabId	saveTokenSet(java.lang.String namespaceURL) Saves the Token Set as a binary stream in the metadata repository.

Method Detail

isSchemaAnnotationAvailable

boolean isSchemaAnnotationAvailable()
                                    throws BinXMLException

Specifies whether the repository performs schema annotations or not. For example for the database (DBBinXMLMetadataProvider) will return true here. The Binary XML Processor calls this API to determine whether to call saveSchema for registering a schema in the repository where the annotations are performed by the repository or call saveCompiledSchema for saving a already annotated schema to the repository. Non-database repositories might typically return false here.

Returns:

true if the repository does schema annotations while saving schemas otherwise the repository returns false

Throws:

BinXMLException

getCompiledSchema

java.io.Reader getCompiledSchema(BinXMLVocabId schemaId)
                                 throws BinXMLException

Fetches the schema as a binary stream from the metadata repository based on the vocabulary id.

Parameters:

schemaId - - vocabulary id of the schema to be fetched

Returns:

binary stream version of the annotated schema doc

Throws:

BinXMLException

getCompiledSchema

java.io.Reader getCompiledSchema(java.lang.String schemaURL)
                                 throws BinXMLException

Fetches the schema as a binary stream from the metadata repository based on the schema URL.

Parameters:

schemaURL - - URL of the schema to be fetched

Returns:

binary stream version of the annotated schema doc

Throws:

BinXMLException

saveSchema

BinXMLVocabId saveSchema(java.lang.String schemaURL)
                         throws BinXMLException

The repository accepts a non-annotated schema, annotates it and saves it as a binary stream in the metadata repository.

Parameters:

schemaURL - - URL of the schema to be saved

Returns:

Returns:

the vocabulary id saved schema

Throws:

BinXMLException

getDTD

BinXMLStream getDTD(BinXMLVocabId dtdId)
                    throws BinXMLException

Parameters:

dtdId - - vocabulary id of the DTD to be fetched

Returns:

binary stream version of the DTD

Throws:

BinXMLException

getDTD

BinXMLStream getDTD(java.lang.String dtdURL)
                    throws BinXMLException

getTokenSet

BinXMLStream getTokenSet(java.lang.String namespaceURL,
                         boolean isAttr)
