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 boolean

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

abstract boolean

Whether any other values are allowed.

abstract long[]

Public methods

flag

public abstract boolean flag()

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

open

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

public abstract long[] value()

Defines the allowed constants for this element
