Constructor Detail

SingleFileCodeBase

public SingleFileCodeBase(ICodeBaseLocator codeBaseLocator,
                          java.lang.String fileName)

Method Detail

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getCodeBaseLocator

public ICodeBaseLocator getCodeBaseLocator()

Description copied from interface: ICodeBase

Get the codebase locator describing the location of this codebase.

Specified by:

getCodeBaseLocator in interface ICodeBase

Returns:

the ICodeBaseLocator

containsSourceFiles

public boolean containsSourceFiles()
                            throws java.lang.InterruptedException

Description copied from interface: ICodeBase

Return whether or not this code base contains any source files.

Specified by:

containsSourceFiles in interface ICodeBase

Returns:

true if the code base contains source file(s), false if it does not contain source files

Throws:

java.lang.InterruptedException

iterator

public ICodeBaseIterator iterator()
                           throws java.lang.InterruptedException

Description copied from interface: IScannableCodeBase

Get an iterator over the resources in the this code base.

Specified by:

iterator in interface IScannableCodeBase

Returns:

ICodeBaseIterator over the resources in the code base

Throws:

java.lang.InterruptedException

lookupResource

public ICodeBaseEntry lookupResource(java.lang.String resourceName)

Description copied from interface: ICodeBase

Look up a resource in this code base.

Specified by:

lookupResource in interface ICodeBase

Parameters:

resourceName - name of the resource to look up

Returns:

ICodeBaseEntry representing the resource or null if the resource cannot be found in this code base

setApplicationCodeBase

public void setApplicationCodeBase(boolean isAppCodeBase)

Description copied from interface: ICodeBase

Designate this code base as an application codebase.

Specified by:

setApplicationCodeBase in interface ICodeBase

Parameters:

isAppCodeBase - true if this is an application codebase, false if not

isApplicationCodeBase

public boolean isApplicationCodeBase()

Description copied from interface: ICodeBase

Return whether or not this codebase is an application codebase.

Specified by:

isApplicationCodeBase in interface ICodeBase

Returns:

true if this is an application codebase, false if not

setHowDiscovered

public void setHowDiscovered(ICodeBase.Discovered howDiscovered)

Description copied from interface: ICodeBase

Set how this codebase was discovered.

Specified by:

setHowDiscovered in interface ICodeBase

Parameters:

howDiscovered - one of the constants SPECIFIED, NESTED, IN_JAR_MANIFEST, or IN_SYSTEM_CLASSPATH

getHowDiscovered

public ICodeBase.Discovered getHowDiscovered()

Description copied from interface: ICodeBase

Return how this codebase was discovered.

Specified by:

getHowDiscovered in interface ICodeBase

Returns:

one of the constants SPECIFIED, NESTED, IN_JAR_MANIFEST, or IN_SYSTEM_CLASSPATH

setLastModifiedTime

public void setLastModifiedTime(long lastModifiedTime)

Description copied from interface: ICodeBase

Set timestamp indicating the most recent time when any of the files in the codebase were modified.

Specified by:

setLastModifiedTime in interface ICodeBase

Parameters:

lastModifiedTime - timestamp when any codebase files were most-recently modified

getLastModifiedTime

public long getLastModifiedTime()

Description copied from interface: ICodeBase

Get timestamp indicating the most recent time when any of the files in the codebase were modified. This information is only likely to be accurate if an ICodeBaseIterator has been used to scan the resources in the codebase (scannable codebases only, obviously).

Specified by:

getLastModifiedTime in interface ICodeBase

Returns:

timestamp when any codebase files were most-recently modified, -1 if unknown

getPathName

public java.lang.String getPathName()

Description copied from interface: ICodeBase

Get the filesystem pathname of this codebase.

Specified by:

getPathName in interface ICodeBase

Returns:

the filesystem pathname of this codebase, or null if this codebase is not accessible via the filesystem

close

public void close()

Description copied from interface: ICodeBase

This method should be called when done using the code base.

Specified by:

close in interface ICodeBase
