Status

enum DiffResource::Status

Enumerator
kDecoded_Status	The resource was specified, exists, read, and decoded.
kCouldNotDecode_Status	The resource was specified, exists, read, but could not be decoded.
kRead_Status	The resource was specified, exists, and read.
kCouldNotRead_Status	The resource was specified, exists, but could not be read.
kExists_Status	The resource was specified and exists.
kDoesNotExist_Status	The resource was specified, but does not exist.
kSpecified_Status	The resource was specified.
kUnspecified_Status	The resource was not specified.
kUnknown_Status	Nothing is yet known about the resource.
kStatusCount	NOT A VALID VALUE – used to set up arrays and to represent an unknown value.

getMatchingStatuses()

bool DiffResource::getMatchingStatuses ( char *  selector, bool  statuses[kStatusCount]  )

static

Sets statuses[i] if it is implied by selector, unsets it if not. Selector may be a comma delimited list of status names, "any", or "failed". Returns true if the selector was entirely understood, false otherwise.

getStatusByName()

DiffResource::Status DiffResource::getStatusByName ( const char *  name )

static

Returns the Status with this name. If there is no Status with this name, returns kStatusCount.

            return static_cast<DiffResource::Status>(status);
        }
    }
    return DiffResource::kStatusCount;
}

getStatusDescription()

const char * DiffResource::getStatusDescription ( DiffResource::Status  status )

static

Returns a text description of the given Status type.

    return StatusDescriptions[status];
}

isStatusFailed()

bool DiffResource::isStatusFailed ( DiffResource::Status  status )

static

Returns true if the Status indicates some kind of failure.

Definition at line 90 of file skdiff.cpp.

                                                           {
