All Implemented Interfaces:

Module

public class EpubModule
extends ModuleBase

Module for validation and metadata extraction on EPUB files. Validation is performed by EPUBCheck https://github.com/w3c/epubcheck/ This module uses the metadata produced by EPUBCheck to produce a JHOVE report.

Method Details

initializeInstance

protected void initializeInstance(Agent moduleAgent)

Initialize core properties - module Agent, format specification Document, and format Signature

Parameters:

agentName -

agentType -

agentAddress -

agentTelephone -

agentEmail -

setupDataStream

protected void setupDataStream(InputStream stream,
 RepInfo info)

Overrides:

setupDataStream in class ModuleBase

checkSignatures

public void checkSignatures(File file,
 InputStream stream,
 RepInfo info)
                     throws IOException

Specified by:

checkSignatures in interface Module

Overrides:

checkSignatures in class ModuleBase

Throws:

IOException

parse

public int parse(InputStream stream,
 RepInfo info,
 int parseIndex)
          throws IOException

Parse the content of a purported EPUB file and store the results in RepInfo.

Specified by:

parse in interface Module

Overrides:

parse in class ModuleBase

Parameters:

stream - An InputStream, positioned at its beginning, which is generated from the object to be parsed. If multiple calls to parse are made on the basis of a nonzero value being returned, a new InputStream must be provided each time.

info - A fresh (on the first call) RepInfo object which will be modified to reflect the results of the parsing If multiple calls to parse are made on the basis of a nonzero value being returned, the same RepInfo object should be passed with each call.

parseIndex - Must be 0 in first call to parse. If parse returns a nonzero value, it must be called again with parseIndex equal to that return value.

Returns:

Throws:

IOException

parse

public void parse(RandomAccessFile file,
 RepInfo info)
           throws IOException

Specified by:

parse in interface Module

Overrides:

parse in class ModuleBase

Throws:

IOException

toUtf8

public static String toUtf8(String inputString)

Make sure the string contains valid UTF-8 characters

Parameters:

inputString -

Returns:

escaped String

initParse

protected void initParse()

Overrides:

initParse in class ModuleBase
