parseString

public static java.lang.Object parseString(java.lang.String value,

getValueFromEnvironment

public static java.lang.String getValueFromEnvironment(java.lang.String key)

Looks up a value by a key from java properties and the system environment. Looks up the provided key first in the java system properties prefixed with SYSTEM_PROPERTY_PREFIX and returns the value if present. If it is not present, looks it up in the system environment prefixed with ENV_VARIABLE_PREFIX and returns this one if present. Returns null if the key is neither found in the properties nor in the environment.

Parameters:

key - the key to look up

Returns:

the found value or null if the key is not available
