Method Detail

performSubstitution

public static void performSubstitution(java.util.Dictionary properties)

Perform substitution on a property set

Parameters:

properties - the property set to perform substitution on

substVars

public static java.lang.String substVars(java.lang.String val,
                                         java.lang.String currentKey,
                                         java.util.Map cycleMap,
                                         java.util.Dictionary configProps)
                                  throws java.lang.IllegalArgumentException

This method performs property variable substitution on the specified value. If the specified value contains the syntax ${<prop-name>}, where <prop-name> refers to either a configuration property or a system property, then the corresponding property value is substituted for the variable placeholder. Multiple variable placeholders may exist in the specified value as well as nested variable placeholders, which are substituted from inner most to outer most. Configuration properties override system properties.

Parameters:

val - The string on which to perform property substitution.

currentKey - The key of the property being evaluated used to detect cycles.

cycleMap - Map of variable references used to detect nested cycles.

configProps - Set of configuration properties.

Returns:

The value of the specified string after system property substitution.

Throws:

java.lang.IllegalArgumentException - If there was a syntax error in the property placeholder syntax or a recursive variable reference.

log

public static void log(org.osgi.framework.BundleContext context,
                       long debug,
                       java.lang.String message,
                       java.lang.Throwable e)

Log a message and optional throwable. If there is a log service we use it, otherwise we log to the console

Parameters:

message - The message to log

e - The throwable to log

jarDir

public static void jarDir(java.io.File directory,
                          java.io.File zipName)
                   throws java.io.IOException

Jar up a directory

Parameters:

directory -

zipName -

Throws:

java.io.IOException

jarDir

public static void jarDir(java.io.File directory,
                          java.io.OutputStream os)

Throws:

java.io.IOException

zipDir

public static void zipDir(java.io.File directory,
                          java.util.zip.ZipOutputStream zos,
                          java.lang.String path,
                          java.util.Set exclusions)
                   throws java.io.IOException

Zip up a directory path

Parameters:

directory -

zos -

path -

exclusions -

Throws:

java.io.IOException

storeChecksum

public static void storeChecksum(org.osgi.framework.Bundle b,
                                 long checksum,
                                 org.osgi.framework.BundleContext bc)

Stores the checksum into a bundle data file.

Parameters:

b - The bundle whose checksum must be stored

checksum - the lastModified date to be stored in bc

bc - the FileInstall's bundle context where to store the checksum.

loadChecksum

public static long loadChecksum(org.osgi.framework.Bundle b,
                                org.osgi.framework.BundleContext bc)

Returns the stored checksum of the bundle.

Parameters:

b - the bundle whose checksum must be returned

bc - the FileInstall's bundle context.

Returns:
