getTokenId

long getTokenId(java.lang.String namespace,
                java.lang.String localName,
                boolean isAttr)
                throws BinXMLException

Fetch a token based on the namespace and localName provided by the user. Check local vocabulary cache; if the token is not available we fetch it from the metadata repository. If token is not found then it will throw a BinXMLException.

Parameters:

namespace - - namespace URL of the token to be fetched

localName - - local name of the token to be fetched

isAttr - - if true will return attribute id else returns element id

Returns:

token id

Throws:

BinXMLException - Raised for any errors encountered

getTokenName

javax.xml.namespace.QName getTokenName(long tokenId)
                                       throws BinXMLException

Fetch a token name based on the tokenId provided by the user. Check local vocabulary cache, if there is no match, then fetch it from metadata repository. If tokenId is not found then throw a BinXMLException.

Returns:

token QName, with name and namespace, based on input tokenId

Throws:

BinXMLException - Raised for any errors encountered

setMetadataRepository

void setMetadataRepository(BinXMLMetadataProvider provider)
                           throws BinXMLException

Users can plug in their own metadata repository that defines the MetadataProvider interface. The DBMetadataProvider implementation to use the Oracle database as a metadata storage repository is available as part of this package. If a non-database repository is needed the user will need to define their own.

provider - - metdata provider implementation
