Class DiskSource

java.lang.Object

org.rhq.enterprise.server.plugins.disk.DiskSource

All Implemented Interfaces:

ContentProvider, PackageSource, RepoSource

public class DiskSource
extends Object
implements ContentProvider, PackageSource, RepoSource

This is the most basic reference implementation of a content source. It provides primative package synchronization with file-system based source. It is anticipated that more content aware subclasses will provide more useful functionality.

Throws:

Exception

getRootDirectory

protected File getRootDirectory()

setRootDirectory

protected void setRootDirectory(File path)

getSupportedPackageTypes

protected Map<String,DiskSource.SupportedPackageType> getSupportedPackageTypes()

setSupportedPackageTypes

protected void setSupportedPackageTypes(Map<String,DiskSource.SupportedPackageType> supportedPackageTypes)

syncPackages

protected void syncPackages(PackageSyncReport report,
                String repoName,
                List<ContentProviderPackageDetails> packages,
                File directory)
                     throws SyncException

Recursive function that drills down into subdirectories and builds up the report of packages for all files found. As files are found, their associated packages are removed from packages if they exist - leaving only packages remaining that do not exist on the file system.

Parameters:

report - the report that we are building up

packages - existing packages not yet found on the file system but exist in server inventory

directory - the directory (and its subdirectories) to scan

Throws:

Exception - if the sync fails

SyncException

Throws:

SyncException

getRelativePath

protected String getRelativePath(File file)

initializePackageTypes

protected void initializePackageTypes()

determinePackageType

protected DiskSource.SupportedPackageType determinePackageType(File file)

generateRepoDetails

protected void generateRepoDetails(RepoImportReport report,
                       File base,
