Method Detail

reset

public void reset()

initialize

public void initialize()

readString

public String readString(String key)

readString

public String readString(String key,
                         String defaultValue)

readStringOptional

public Optional<String> readStringOptional(String key)

readStringOptional

public Optional<String> readStringOptional(TigerConfigurationKey key)

instantiateConfigurationBean

public <T> Optional<T> instantiateConfigurationBean(Class<T> configurationBeanClass,
                                                    String... baseKeys)

Instantiates a bean of the given class. The base-keys denote the point from which the keys are taken. If values can not be substituted (e.g. ${key.that.does.not.exist}) they are simply returned as a string. This behaviour is more relaxed towards input errors but might delay failures from startup to runtime.

If the base-keys lead to a non-defined (i.e. empty) node in the tree (no values have been read) an empty optional is returned.

Type Parameters:

T -

Parameters:

configurationBeanClass - The class of the configuration bean

baseKeys - Where in the configuration tree should the values be taken from?

Returns:

An instance of configurationBeanClass filled with values taken from the configuration tree

instantiateConfigurationBeanStrict

public <T> Optional<T> instantiateConfigurationBeanStrict(Class<T> configurationBeanClass,
                                                          String... baseKeys)

Instantiates a bean of the given class. The base-keys denote the point from which the keys are taken. If values can not be substituted (e.g. ${key.that.does.not.exist}) an empty value is returned. This behaviour follows the "fail fast, fail early" approach.

If the base-keys lead to a non-defined (i.e. empty) node in the tree (no values have been read) an empty optional is returned.

Type Parameters:

T -

Parameters:

configurationBeanClass - The class of the configuration bean

baseKeys - Where in the configuration tree should the values be taken from?

Returns:

An instance of configurationBeanClass filled with values taken from the configuration tree
