Public methods
equals
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 returntrue
. - It is symmetric: for any non-null reference values
x
andy
,x.equals(y)
should returntrue
if and only ify.equals(x)
returnstrue
. - It is transitive: for any non-null reference values
x
,y
, andz
, ifx.equals(y)
returnstrue
andy.equals(z)
returnstrue
, thenx.equals(z)
should returntrue
. - It is consistent: for any non-null reference values
x
andy
, multiple invocations ofx.equals(y)
consistently returntrue
or consistently returnfalse
, provided no information used inequals
comparisons on the objects is modified. - For any non-null reference value
x
,x.equals(null)
should returnfalse
.
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
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
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, android.app.appsearch.AppSearchResult.RESULT_RATE_LIMITED, or android.app.appsearch.AppSearchResult.RESULT_TIMED_OUT |
getResultValue
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
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 inequals
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 thehashCode
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 thehashCode
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

Returns true
if getResultCode()
equals AppSearchResult#RESULT_OK
.
Returns | |
---|---|
boolean |
