Public methods

equals

Added in API level 31
public boolean equals (Object other)

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
other Object: This value may be null.

Returns
boolean true if this object is the same as the obj argument; false otherwise.

getErrorMessage

Added in API level 31
public String getErrorMessage ()

Returns the error message associated with this result.

If isSuccess() is true, the error message is always null. The error message may be null even if isSuccess() is false. See the documentation of the particular AppSearchSession call producing this AppSearchResult for what is returned by getErrorMessage().

Returns
String

getResultCode

Added in API level 31
public int getResultCode ()

Returns one of the RESULT constants defined in AppSearchResult.

Returns
int Value is RESULT_OK, RESULT_UNKNOWN_ERROR, RESULT_INTERNAL_ERROR, RESULT_INVALID_ARGUMENT, RESULT_IO_ERROR, RESULT_OUT_OF_SPACE, RESULT_NOT_FOUND, RESULT_INVALID_SCHEMA, RESULT_SECURITY_ERROR, android.app.appsearch.AppSearchResult.RESULT_DENIED, or android.app.appsearch.AppSearchResult.RESULT_RATE_LIMITED

getResultValue

Added in API level 31
public ValueType getResultValue ()

Returns the result value associated with this result, if it was successful.

See the documentation of the particular AppSearchSession call producing this AppSearchResult for what is placed in the result value by that call.

Returns
ValueType This value may be null.

Throws
IllegalStateException if this AppSearchResult is not successful.

hashCode

Added in API level 31
public int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

Returns
int a hash code value for this object.

isSuccess

Added in API level 31
public boolean isSuccess ()

Returns true if getResultCode() equals AppSearchResult#RESULT_OK.

Returns
boolean

newFailedResult

Added in API level 31
public static AppSearchResult<ValueType> newFailedResult (int resultCode, 
                String errorMessage)

Creates a new failed AppSearchResult.

Parameters
resultCode int: One of the constants documented in AppSearchResult#getResultCode. Value is RESULT_OK, RESULT_UNKNOWN_ERROR, RESULT_INTERNAL_ERROR, RESULT_INVALID_ARGUMENT, RESULT_IO_ERROR, RESULT_OUT_OF_SPACE, RESULT_NOT_FOUND, RESULT_INVALID_SCHEMA, RESULT_SECURITY_ERROR, android.app.appsearch.AppSearchResult.RESULT_DENIED, or android.app.appsearch.AppSearchResult.RESULT_RATE_LIMITED

errorMessage String: An optional string describing the reason or nature of the failure. This value may be null.

Returns
AppSearchResult<ValueType> This value cannot be null.

newSuccessfulResult

Added in API level 31
public static AppSearchResult<ValueType> newSuccessfulResult (ValueType value)

Creates a new successful AppSearchResult.

Parameters
value ValueType: An optional value to associate with the successful result of the operation being performed. This value may be null.

Returns
AppSearchResult<ValueType> This value cannot be null.

toString

Added in API level 31
public String toString ()

Returns a string representation of the object.

Returns
String This value cannot be null.
