Constructor Details

JNLPMatcher

public JNLPMatcher(InputStream appTemplate,
 InputStream launchJNLP,
 boolean isTemplate,
 ParserSettings p)
            throws JNLPMatcherException

Public constructor

Parameters:

appTemplate - the reader stream of the signed APPLICATION.jnlp or APPLICATION_TEMPLATE.jnlp

launchJNLP - the reader stream of the launching JNLP file

isTemplate - a boolean that specifies if appTemplateFile is a template

p - settings of parser

Throws:

JNLPMatcherException - if IOException, XMLParseException is thrown during parsing; Or launchJNLP/appTemplate is null

Method Details

isMatch

public boolean isMatch()

Compares both JNLP files

Returns:

true if both JNLP files are 'matched', otherwise false

matchNodes

private boolean matchNodes(XmlNode appTemplate,
 XmlNode launchJNLP)

Compares two Nodes regardless of the order of their children/attributes

Parameters:

appTemplate - signed application or template's Node

launchJNLP - launching JNLP file's Node

Returns:

true if both Nodes are 'matched', otherwise false

matchAttributes

private boolean matchAttributes(XmlNode templateNode,
 XmlNode launchNode)

Compares attributes of two Nodes regardless of order

Parameters:

templateNode - signed application or template's XmlNode with attributes

launchNode - launching JNLP file's XmlNode with attributes

Returns:

true if both Nodes have 'matched' attributes, otherwise false

closeInputStream

private void closeInputStream(InputStream stream)

Closes an input stream

Parameters:

stream - The input stream that will be closed

closeOutputStream

private void closeOutputStream(OutputStream stream)

Closes an output stream

Parameters:

stream - The output stream that will be closed
