DataSourceImpl

This class represents an abstract data source object.

interface DataSourceImpl {

size_t read(ubyte* output, size_t length);

size_t peek(ubyte* output, size_t length, size_t peek_offset);

bool endOfData();

size_t readByte(ubyte output);

size_t peekByte(ubyte output);

size_t discardNext(size_t n);

size_t getBytesRead();

}

Members

Functions

discardNext size_t discardNext(size_t n): Discard the next N bytes of the data
endOfData bool endOfData(): Test whether the source still has data that can be read.
getBytesRead size_t getBytesRead()
id string id(): return the id of this data source
peek size_t peek(ubyte* output, size_t length, size_t peek_offset): Read from the source but do not modify the internal offset. Consecutive calls to peek() will return portions of the source starting at the same position.
peekByte size_t peekByte(ubyte output): Peek at one ubyte.
read size_t read(ubyte* output, size_t length): Read from the source. Moves the internal offset so that every call to read will return a new portion of the source.
readByte size_t readByte(ubyte output): Read one ubyte.
