Extension functions
getBlobOrNull
inline fun Cursor.getBlobOrNull(index: Int): ByteArray?
Returns the value of the requested column as a nullable byte array.
The result and whether this method throws an exception when the column type is not a blob type is implementation-defined.
getDoubleOrNull
inline fun Cursor.getDoubleOrNull(index: Int): Double?
Returns the value of the requested column as a nullable double.
The result and whether this method throws an exception when the column type is not a floating-point type is implementation-defined.
getFloatOrNull
inline fun Cursor.getFloatOrNull(index: Int): Float?
Returns the value of the requested column as a nullable float.
The result and whether this method throws an exception when the column type is not a floating-point type is implementation-defined.
getIntOrNull
inline fun Cursor.getIntOrNull(index: Int): Int?
Returns the value of the requested column as a nullable integer.
The result and whether this method throws an exception when the column type is not an integral type is implementation-defined.
getLongOrNull
inline fun Cursor.getLongOrNull(index: Int): Long?
Returns the value of the requested column as a nullable long.
The result and whether this method throws an exception when the column type is not an integral type is implementation-defined.
