Constructor Detail

Configuration

public Configuration(FeedIdStrategy feedIdStrategy,

                     Map<String,String> implementationConfiguration)

Method Detail

getFeedIdStrategy

public FeedIdStrategy getFeedIdStrategy()

getResultFilter

public ResultFilter getResultFilter()

Returns:

the result filter to be used to filter the query results or null if none necessary

getProperty

public String getProperty(Configuration.Property property,
                          String defaultValue)

Returns the value of the property.

If there is a system property with the name from Configuration.Property.getSystemPropertyNames() ()}, then its value is returned, otherwise if the property defines an environment variable and that env variable exists, then its value is returned otherwise the value of a property with a name from Configuration.Property.getPropertyName() from the values loaded using Configuration.Builder.withConfiguration(Map) or Configuration.Builder.withConfiguration(Properties) is returned.

Parameters:

property - the property to obtain

Returns:

the value or null if none found

getImplementationConfiguration

public Map<String,String> getImplementationConfiguration(Collection<? extends Configuration.Property> overridableProperties)

Returns the implementation configuration with the values changed to conform the provided properties. I.e. if a system property defined by some of the provided property objects overrides a property in the implementation configuration, the value of the system property is used instead for that property (i.e. the key stays the same but the value gets overridden to the value of the system property).

Parameters:

overridableProperties - the properties to override the implementation configuration with.

Returns:

an overridden implementation configuration
