LongDef

@Retention(value = SOURCE)  @Target(value = ) 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})

Summary

Public methods

abstract @NonNull boolean

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

abstract @NonNull boolean

Whether any other values are allowed.

abstract @NonNull long[]

Defines the allowed constants for this element

Public methods

flag

@NonNull
public abstract boolean flag()

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

open

@NonNull
public abstract boolean open()

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

@NonNull
public abstract long[] value()

Defines the allowed constants for this element
