Method Detail

retrieveOsSpecificProperty

public String retrieveOsSpecificProperty(String prefix,
                                         String defaultValue)

Retrieves the best available configuration/property value instead of just retrieving the best matching key.

Specified by:

retrieveOsSpecificProperty in interface OsConfigurationService

Parameters:

prefix - the common prefix of all property keys to obey

defaultValue - the default value to return is no such property exists

Returns:

the property value of the best matching key or the given defaultValue if no such key exists.

See Also:

OsConfigurationService.retrieveOsSpecificProperty(String, String)

retrieveOsConfigurationKey

public String retrieveOsConfigurationKey(String prefix)
                                  throws NoSuchConfigurationKeyException

Retrieves the best available configuration/property key for the given prefix. This method behaves exactly the same as OsConfigurationService.retrieveOsDirectory(File), but operates on the ConfigurationService properties instead of file system directories.

Specified by:

retrieveOsConfigurationKey in interface OsConfigurationService

Parameters:

prefix - the common prefix of all property keys to obey

Returns:

the property key matching best this system

Throws:

NoSuchConfigurationKeyException - if no configuration keys for the given prefix exist

See Also:

OsConfigurationService.retrieveOsConfigurationKey(java.lang.String)

doRetrieveOsConfigurationKey

protected String doRetrieveOsConfigurationKey(String prefix)
                                       throws NoSuchConfigurationKeyException

Does the actual property key resolution (without the cache).

Parameters:

prefix - the prefix of the configuration key in question

Returns:

the os specific configuration key

Throws:

NoSuchConfigurationKeyException - if no such configuration key exists

See Also:

OsConfigurationService.retrieveOsConfigurationKey(String)

retrieveOsDirectory

public File retrieveOsDirectory(File rootDirectory)

Evaluates the directory structure of the given rootDirectory and return the best matching os specific folder.

Specified by:

retrieveOsDirectory in interface OsConfigurationService

Parameters:

rootDirectory - the base directory containing the two level folder hierarchy of os.name/os.arch

Returns:

the directory matching best to the system.

See Also:

OsConfigurationService.retrieveOsDirectory(File)

doRetrieveOsDirectory

protected File doRetrieveOsDirectory(File root)

Resolves the os specific directory (without the caching).

Parameters:

root - the root directory to analyse.

Returns:

the best matching directory within the given root for the current operation system and architecture.

getConfigurationService

public ConfigurationService getConfigurationService()

Accesses the ConfigurationService to use for property (key) resolution.

Returns:

the ConfigurationService to use

setConfigurationService

public void setConfigurationService(ConfigurationService configurationService)

Sets the ConfigurationService to use for property (key) resolution. This setter is for Spring IoC wiring.

Parameters:

configurationService - the ConfigurationService to use

getOsName

public String getOsName()

Accesses this systems operation system name. This property is preset to System.getProperty("os.name") , but can be overwritten through spring configuration.

Returns:

this systems operation system name.

See Also:

System.getProperties()

setOsName

public void setOsName(String osName)

Sets this systems operation system name. This property is preset to System.getProperty("os.name"), but can be overwritten through spring configuration.

Parameters:

osName - the name of this systems operation system.

See Also:

System.getProperties()

getOsArch

public String getOsArch()

Accesses this systems operation system architecture. This property is preset to System.getProperty("os.arch"), but can be overwritten through spring configuration.

Returns:

this systems operation system architecture name.

See Also:

System.getProperties()

setOsArch

public void setOsArch(String osArch)

Sets this systems operation system architecture name. This property is preset to System.getProperty("os.arch"), but can be overwritten through spring configuration.

Parameters:

osArch - the name of this systems operation system architecture.
