Method Detail

getCarbonConfigHome

public static Path getCarbonConfigHome()

This method will return the carbon configuration directory path. i.e ${carbon.home}/conf

Returns:

returns the Carbon Configuration directory path

getCarbonHome

public static Path getCarbonHome()

Returns the Carbon Home directory path. If carbon.home system property is not found, gets the CARBON_HOME_ENV system property value and sets to the carbon home.

Returns:

returns the Carbon Home directory path

getRuntimePath

public static Path getRuntimePath()

Returns the Runtime Home directory path. If wso2.runtime.path system property is not found, gets the RUNTIME_PATH_ENV system property value and sets to the runtime home.

Returns:

the Runtime Home directory path

getRuntimeConfigPath

public static Path getRuntimeConfigPath()

Get the conf path of the runtime.

Returns:

Path to the conf dir of runtime

getRuntimeName

public static String getRuntimeName()

get the current Runtime name.

Returns:

the Runtime name

substituteVariables

public static String substituteVariables(String value)

Replace system property holders in the property values. e.g. Replace ${carbon.home} with value of the carbon.home system property.

Parameters:

value - string value to substitute

Returns:

String substituted string

getSystemVariableValue

public static String getSystemVariableValue(String variableName,
                                            String defaultValue)

A utility which allows reading variables from the environment or System properties. If the variable in available in the environment as well as a System property, the System property takes precedence.

Parameters:

variableName - System/environment variable name

defaultValue - default value to be returned if the specified system variable is not specified.

Returns:

value of the system/environment variable

getSystemVariableValue

public static String getSystemVariableValue(String variableName,
                                            String defaultValue,
                                            Class constantClass)

A utility which allows reading variables from the environment or System properties. If the variable in available in the environment as well as a System property, the System property takes precedence.

Parameters:

variableName - System/environment variable name

defaultValue - default value to be returned if the specified system variable is not specified.

constantClass - Class from which the Predefined value should be retrieved if system variable and default value is not specified.

Returns:

value of the system/environment variable

checkSecurity

public static void checkSecurity()

When the java security manager is enabled, the checkSecurity method can be used to protect/prevent methods being executed by unsigned code.

getCarbonRuntimes

public static List<String> getCarbonRuntimes()
                                      throws IOException

Returns a list of WSO2 Carbon Runtime names.

Returns:

WSO2 Carbon Runtime names

Throws:

IOException - if an I/O error occurs
