Configuration

@Deprecated
public Configuration()

Deprecated

Use ConfigurationBuilder and ConfigurationSource that allow to provide all properties before creating configuration and keep it immutable.

Constructs a configuration containing the known Azure properties constants.

Method Details

get

public T get(ConfigurationProperty property)

Gets property value from all available sources in the following order:

Property value is converted to specified type. If property value is missing and not required, default value is returned.

ConfigurationProperty<String> property = ConfigurationPropertyBuilder.ofString("http.proxy.hostname")
     .shared(true)
     .logValue(true)
     .systemPropertyName("http.proxyHost")
     .build();

 // attempts to get local `azure.sdk.<client-name>.http.proxy.host` property and falls back to
 // shared azure.sdk.http.proxy.port
 System.out.println(configuration.get(property));

Parameters:

property - instance.

Returns:

The value of the property if it exists, otherwise the default value of the property.

get

public T get(String name, T defaultValue)

Gets the value of system property or environment variable converted to given primitive T using corresponding parse method on this type. Use get(ConfigurationProperty<T> property) overload to get explicit configuration or environment configuration from specific source.

This method first checks the values previously loaded from the environment, if the configuration is found there it will be returned. Otherwise, this will attempt to load the value from the environment.

If no configuration is found, the defaultValue is returned.

Following types are supported:

  • Byte
  • Short
  • Integer
  • Long
  • Float
  • Double
  • Boolean

Parameters:

name - Name of the configuration.
defaultValue - Value to return if the configuration isn't found.

Returns:

The converted configuration if found, otherwise the default value is returned.

get

public T get(String name, Function converter)

Gets the value of system property or environment variable and converts it with the converter.

This method first checks the values previously loaded from the environment, if the configuration is found there it will be returned. Otherwise, this will attempt to load the value from the environment.

If no configuration is found the converter won't be called and null will be returned.

Parameters:

name - Name of the configuration.
converter - Converter used to map the configuration to T.

Returns:

The converted configuration if found, otherwise null.

contains

public boolean contains(ConfigurationProperty property)

Checks if configuration contains the property. If property can be shared between clients, checks this Configuration and falls back to shared section. If property has aliases, system property or environment variable defined, checks them as well.

Value is not validated.

Parameters:

property - instance.

Returns:

true if property is available, false otherwise.

contains

public boolean contains(String name)

Determines if the system property or environment variable is defined.

Use contains(ConfigurationProperty<?> property) overload to get explicit configuration or environment configuration from specific source.

This only checks against values previously loaded into the Configuration object, this won't inspect the environment for containing the value.

Parameters:

name - Name of the configuration.

Returns:

True if the configuration exists, otherwise false.

get

public String get(String name)

Gets the value of system property or environment variable. Use get(ConfigurationProperty<T> property) overload to get explicit configuration or environment configuration from specific source.

Parameters:

name - Name of the configuration.

Returns:

Value of the configuration if found, otherwise null.

Returns:

The global configuration store.

put

@Deprecated

This will overwrite the previous configuration value if it existed.

Parameters:

name - Name of the configuration.
value - Value of the configuration.
