Member Function Documentation

operator()()

bool Asset::operator() ( void *  buffer, msize  bytes  )

virtual

Reads a given number of bytes into a specific memory location.

Parameters

[in]	buffer	The address to store the data to
[in]	bytes	Number of bytes to read

Returns

true on success.

Implements Beatmup::InputStream.

    if (bytes == 0)
        return true;
    return AAsset_read(asset, buffer, bytes) > 0;
}

seek()

bool Asset::seek ( msize  pos )

virtual

Moves the read pointer to a given position in the stream.

Parameters

pos	The position in bytes from the beginning of the stream

Returns

true on success.

Implements Beatmup::InputStream.
