public ParametersService()

Method Details

init

public void init(ParametersConfig parametersConfig,
 String applicationId)

Initialize the cache and parameters client

Parameters:

parametersConfig - the parameters management configuration

getValue

public <T> T getValue(String propertyName,
 Class<T> propertyType,
 String defaultValue)

Return the resolved property value with the specified type for the specified property name from the underlying configuration sources.

The configuration value is not guaranteed to be cached by the implementation, and may be expensive to compute; therefore, if the returned value is intended to be frequently used, callers should consider storing rather than recomputing it.

Type Parameters:

T - The property type

Parameters:

propertyName - The configuration property name

propertyType - The type into which the resolved property value should get converted

defaultValue - The default value to return if the property value could not get resolved

Returns:

the resolved property value as an instance of the requested type

Throws:

IllegalArgumentException - if the property cannot be converted to the specified type

NoSuchElementException - if the property isn't present in the configuration

getValue

public <T> T getValue(String propertyName,
 Class<T> propertyType)

Return the resolved property value with the specified type for the specified property name from the underlying configuration sources.

The configuration value is not guaranteed to be cached by the implementation, and may be expensive to compute; therefore, if the returned value is intended to be frequently used, callers should consider storing rather than recomputing it.

This is a shortcut to the getValue method using null as defaultValue.

Type Parameters:

T - The property type

Parameters:

propertyName - The configuration property name

propertyType - The type into which the resolved property value should get converted

Returns:

the resolved property value as an instance of the requested type

Throws:

IllegalArgumentException - if the property cannot be converted to the specified type

NoSuchElementException - if the property isn't present in the configuration
