Method Detail

addRecognizedOption

public void addRecognizedOption(String option,
                                int optionProperties,
                                String helpText)

Set the permitted options.

Parameters:

option - A permitted option.

setPermittedValues

public void setPermittedValues(String option,
                               String[] values,
                               String defaultValue)

Set the permitted values for an option

Parameters:

option - the option keyword

values - the set of permitted values

defaultValue - the default value if the option is supplied but no value is given. May be null if no default is defined.

setActualOptions

public void setActualOptions(String[] args)
                      throws XPathException

Set the actual options

Throws:

XPathException

definesParameterValues

public boolean definesParameterValues()

Test whether there is any keyword=value option present

testIfSchemaAware

public boolean testIfSchemaAware()

Prescan the command line arguments to see if any of them imply use of a schema-aware processor

Returns:

true if a schema-aware processor is needed

applyToConfiguration

public void applyToConfiguration(Configuration config)
                          throws TransformerException

Apply options to the Configuration

Parameters:

config - the Configuration

Throws:

TransformerException

displayPermittedOptions

public String displayPermittedOptions()

Display the list the permitted options

Returns:

the list of permitted options, as a string

getOptionValue

public String getOptionValue(String option)

Get the value of a named option. Returns null if the option was not present on the command line. Returns "" if the option was present but with no value ("-x" or "-x:").

Parameters:

option - the option keyword

Returns:

the option value, or null if not specified.

getPositionalOptions

public List<String> getPositionalOptions()

Get the options specified positionally, that is, without a leading "-"

setParams

public void setParams(Configuration config,
                      Controller controller,
                      DynamicQueryContext qcontext,
                      Properties outputProperties)
               throws TransformerException

Apply requested parameters to a controller, a query context, or a set of output properties, as appropriate

Parameters:

controller - The controller to be used for a transformation. May be null.

qcontext - The dynamic query context. May be null.

outputProperties - the serialization properties. May be null.

Throws:

TransformerException

loadDocuments

public static Object loadDocuments(String sourceFileName,
                                   boolean useURLs,
                                   Configuration config,
