+/**
+ * Function type for data transformation.
+ * Transforms data, or just returns the length of the data if
+ * the input length is -1.
+ * Swap functions assume that their data pointers are aligned properly.
+ *
+ * Quick implementation outline:
+ * (best to copy and adapt and existing swapper implementation)
+ * check that the data looks like the expected format
+ * if(length<0) {
+ * preflight:
+ * never dereference outData
+ * read inData and determine the data size
+ * assume that inData is long enough for this
+ * } else {
+ * outData can be NULL if length==0
+ * inData==outData (in-place swapping) possible but not required!
+ * verify that length>=(actual size)
+ * if there is a chance that not every byte up to size is reached
+ * due to padding etc.:
+ * if(inData!=outData) {
+ * memcpy(outData, inData, actual size);
+ * }
+ * swap contents
+ * }
+ * return actual size
+ *
+ * Further implementation notes:
+ * - read integers from inData before swapping them
+ * because in-place swapping can make them unreadable
+ * - compareInvChars compares a local Unicode string with already-swapped
+ * output charset strings
+ *
+ * @param ds Pointer to UDataSwapper containing global data about the
+ * transformation and function pointers for handling primitive
+ * types.
+ * @param inData Pointer to the input data to be transformed or examined.
+ * @param length Length of the data, counting bytes. May be -1 for preflighting.
+ * If length>=0, then transform the data.
+ * If length==-1, then only determine the length of the data.
+ * The length cannot be determined from the data itself for all
+ * types of data (e.g., not for simple arrays of integers).
+ * @param outData Pointer to the output data buffer.
+ * If length>=0 (transformation), then the output buffer must
+ * have a capacity of at least length.
+ * If length==-1, then outData will not be used and can be NULL.
+ * @param pErrorCode ICU UErrorCode parameter, must not be NULL and must
+ * fulfill U_SUCCESS on input.
+ * @return The actual length of the data.
