Enum Constant Detail

SYNC_HTTP_SERVICE_IMPL

public static final SdkSystemSetting SYNC_HTTP_SERVICE_IMPL

Explicitly identify the default synchronous HTTP implementation the SDK will use. Useful when there are multiple implementations on the classpath or as a performance optimization since implementation discovery requires classpath scanning.

ASYNC_HTTP_SERVICE_IMPL

public static final SdkSystemSetting ASYNC_HTTP_SERVICE_IMPL

Explicitly identify the default Async HTTP implementation the SDK will use. Useful when there are multiple implementations on the classpath or as a performance optimization since implementation discovery requires classpath scanning.

Method Detail

values

public static SdkSystemSetting[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (SdkSystemSetting c : SdkSystemSetting.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static SdkSystemSetting valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

property

public String property()

Description copied from interface: SystemSetting

The system property of the setting (or null if there is no property for this setting).

Specified by:

property in interface SystemSetting

environmentVariable

public String environmentVariable()

Description copied from interface: SystemSetting

The environment variable of the setting (or null if there is no environment variable for this setting).

Specified by:

environmentVariable in interface SystemSetting

defaultValue

public String defaultValue()

Description copied from interface: SystemSetting

The default value of the setting (or empty if there is no default). This value will be applied if the customer did not specify a setting.

Specified by:

defaultValue in interface SystemSetting
