@ThreadSafe
public abstract class AbstractAnalyzer
extends java.lang.Object
implements Analyzer

Base class for analyzers to avoid code duplication of prepare and close as most analyzers do not need these methods.

Method Detail

isEnabled

public boolean isEnabled()

Get the value of enabled.

Specified by:

isEnabled in interface Analyzer

Returns:

the value of enabled

setEnabled

public void setEnabled(boolean enabled)

Set the value of enabled.

Parameters:

enabled - new value of enabled

getSettings

protected Settings getSettings()

Returns the configured settings.

Returns:

the configured settings

initialize

public void initialize(Settings settings)

Initializes the analyzer with the configured settings.

Specified by:

initialize in interface Analyzer

Parameters:

settings - the configured settings to use

prepare

public final void prepare(Engine engine)
                   throws InitializationException

Initialize the abstract analyzer.

Specified by:

prepare in interface Analyzer

Parameters:

engine - a reference to the dependency-check engine

Throws:

InitializationException - thrown if there is an exception

prepareAnalyzer

protected void prepareAnalyzer(Engine engine)
                        throws InitializationException

Prepares a given Analyzer. This will be skipped if the analyzer is disabled.

Parameters:

engine - a reference to the dependency-check engine

Throws:

InitializationException - thrown if there is an exception

analyze

public final void analyze(Dependency dependency,
                          Engine engine)
                   throws AnalysisException

Analyzes a given dependency. If the dependency is an archive, such as a WAR or EAR, the contents are extracted, scanned, and added to the list of dependencies within the engine.

Specified by:

analyze in interface Analyzer

Parameters:

dependency - the dependency to analyze

engine - the engine scanning

Throws:

AnalysisException - thrown if there is an analysis exception

analyzeDependency

protected abstract void analyzeDependency(Dependency dependency,
                                          Engine engine)
                                   throws AnalysisException

Analyzes a given dependency. If the dependency is an archive, such as a WAR or EAR, the contents are extracted, scanned, and added to the list of dependencies within the engine.

Parameters:

dependency - the dependency to analyze

engine - the engine scanning

Throws:

AnalysisException - thrown if there is an analysis exception

close

public final void close()
                 throws java.lang.Exception

The close method does nothing for this Analyzer.
