IntDef

public abstract @interface IntDef
implements Annotation

android.support.annotation.IntDef

---

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

Example:

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

For a flag, set the flag attribute:

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

Summary

Inherited methods

From interface java.lang.annotation.Annotation abstract Class<? extends Annotation> annotationType() Returns the annotation type of this annotation. abstract boolean equals(Object obj) Returns true if the specified object represents an annotation that is logically equivalent to this one. abstract int hashCode() Returns the hash code of this annotation, as defined below: The hash code of an annotation is the sum of the hash codes of its members (including those with default values), as defined below: The hash code of an annotation member is (127 times the hash code of the member-name as computed by hashCode()) XOR the hash code of the member-value, as defined below: The hash code of a member-value depends on its type: The hash code of a primitive value v is equal to WrapperType.valueOf(v).hashCode(), where WrapperType is the wrapper type corresponding to the primitive type of v (Byte, Character, Double, Float, Integer, Long, Short, or Boolean). abstract String toString() Returns a string representation of this annotation.
