virtual char * GetAppendBuffer(int32_t min_capacity, int32_t desired_capacity_hint, char *scratch, int32_t scratch_capacity, int32_t *result_capacity)
Returns a writable buffer for appending and writes the buffer's capacity to *result_capacity.
StringByteSink(StringClass *dest)
Constructs a ByteSink that will append bytes to the dest string.
int32_t NumberOfBytesWritten() const
Returns the number of bytes actually written to the sink.
virtual void Append(const char *data, int32_t n)
Append "bytes[0,n-1]" to this.
UBool Overflowed() const
Returns true if any bytes were discarded, i.e., if there was an attempt to write more than 'capacity'...
ByteSink()
Default constructor.
A ByteSink can be filled with bytes.
virtual void Append(const char *bytes, int32_t n)=0
Append "bytes[0,n-1]" to this.
