Wrapper class for UErrorCode, with conversion operators for direct use in ICU C and C++ APIs.
Definition: errorcode.h:84
UBool isFailure() const
Tests for U_FAILURE().
Definition: errorcode.h:100
virtual ~ErrorCode()
Destructor, does nothing.
virtual void handleFailure() const
Called by assertSuccess() if isFailure() is true.
Definition: errorcode.h:137
void assertSuccess() const
Asserts isSuccess().
UErrorCode errorCode
Internal UErrorCode, accessible to subclasses.
Definition: errorcode.h:130
UBool isSuccess() const
Tests for U_SUCCESS().
Definition: errorcode.h:98
const char * errorName() const
Return a string for the UErrorCode value.
void set(UErrorCode value)
Sets the UErrorCode value.
Definition: errorcode.h:104
UErrorCode reset()
Returns the UErrorCode value and resets it to U_ZERO_ERROR.
UErrorCode get() const
Returns the UErrorCode value.
Definition: errorcode.h:102
ErrorCode()
Default constructor.
Definition: errorcode.h:90
UMemory is the common ICU base class.
Definition: uobject.h:115
int8_t UBool
The ICU boolean type, a signed-byte integer.
Definition: umachine.h:269
C++ API: Common ICU base class UObject.
Basic definitions for ICU, for both C and C++ APIs.
UErrorCode
Standard ICU4C error code type, a substitute for exceptions.
Definition: utypes.h:415
@ U_ZERO_ERROR
No error, no warning.
Definition: utypes.h:449
#define U_FAILURE(x)
Does the error code indicate a failure?
Definition: utypes.h:717
#define U_SUCCESS(x)
Does the error code indicate success?
Definition: utypes.h:712
#define U_COMMON_API
Set to export library symbols from inside the common library, and to import them from outside.
Definition: utypes.h:300
