LongDef

  • Cmn
    @Retention(value = AnnotationRetention.SOURCE)
    @Target(allowedTargets = [AnnotationTarget.ANNOTATION_CLASS])
    annotation LongDef

Denotes that the annotated long element represents a logical type and that its value should be one of the explicitly named constants. If the LongDef#flag() attribute is set to true, multiple constants can be combined.

Example:

@Retention(SOURCE)
@LongDef({NAVIGATION_MODE_STANDARD, NAVIGATION_MODE_LIST, NAVIGATION_MODE_TABS})
public @interface NavigationMode {}
public static final long NAVIGATION_MODE_STANDARD = 0;
public static final long NAVIGATION_MODE_LIST = 1;
public static final long NAVIGATION_MODE_TABS = 2;
...
public abstract void setNavigationMode(@NavigationMode long mode);
@NavigationMode
public abstract long getNavigationMode();

For a flag, set the flag attribute:

@LongDef(
    flag = true,
    value = {NAVIGATION_MODE_STANDARD, NAVIGATION_MODE_LIST, NAVIGATION_MODE_TABS}
)

LongDef(vararg value: Long = [], flag: Boolean = false, open: Boolean = false)

Public properties

flag

Cmn 
val flag: Boolean

Defines whether the constants can be used as a flag, or just as an enum (the default)

open

Cmn 
val open: Boolean

Whether any other values are allowed. Normally this is not the case, but this allows you to specify a set of expected constants, which helps code completion in the IDE and documentation generation and so on, but without flagging compilation warnings if other values are specified.

value

Cmn 
val value: LongArray

Defines the allowed constants for this element
