public SQLFunctionSet()

Method Detail

setConfiguration

public void setConfiguration(Configuration config)

Description copied from interface: FunctionLibrary

Supply details of the configuration in use.

Parameters:

config - the configuration. The default implementation does nothing (many function libraries do not need to know any configuration details)

sqlQueryResult

public static java.util.List<MapItem> sqlQueryResult(java.sql.ResultSet rs)
                                              throws java.sql.SQLException

Throws:

java.sql.SQLException

setSqlStatementParam

public static void setSqlStatementParam(java.sql.PreparedStatement ps,
                                        int index,
                                        Sequence value,
                                        XPathContext context)
                                 throws XPathException

Throws:

XPathException

supplyParameters

public static void supplyParameters(java.sql.ParameterMetaData metaData,
                                    SequenceType[] parameterTypes)
                             throws java.sql.SQLException

Throws:

java.sql.SQLException

expectConnection

public static java.sql.Connection expectConnection(Sequence arg,
                                                   XPathContext context)
                                            throws XPathException

Throws:

XPathException

getNamespace

public NamespaceUri getNamespace()

Return the namespace URI for the functions local to this function set.

Overrides:

getNamespace in class BuiltInFunctionSet

Returns:

the namespace URI of the functions local to this function set. Note that functions imported from another function set may have a different namespace URI.

getConventionalPrefix

public java.lang.String getConventionalPrefix()

Description copied from class: BuiltInFunctionSet

Return a conventional prefix for use with this namespace, typically the prefix used in the documentation of these functions.

Overrides:

getConventionalPrefix in class BuiltInFunctionSet

Returns:

the string "fn"
