Constructor Details

LabelValidator

public LabelValidator()
               throws ParserConfigurationException,
TransformerConfigurationException

Default constructor.

Throws:

ParserConfigurationException - If there was an error setting up the configuration of the parser that is reposnible for doing the label validation.

TransformerConfigurationException - If there was an error setting up the Transformer responsible for doing the transformations of the schematrons.

Method Details

getFilesProcessed

public long getFilesProcessed()

Returns the number of files processed by the validation function.

getTotalTimeElapsed

public double getTotalTimeElapsed()

Returns the duration it took to run the validation function.

setSchema

public void setSchema(List<URL> schemaFiles)

Pass in a list of schemas to validate against.

Parameters:

schemaFiles - A list of schema URLs.

setSchematrons

public void setSchematrons(List<String> schematrons)

Pass in a list of transformed schematrons to validate against.

Parameters:

schematrons - A list of transformed schematrons.
