class Geo::IGeoInputStream

An IGeoInputStream allows you to read memory/files in a consistent manner, and is an extension point for users wishing to control where data is stored.

The simplest implementation is

GeoFileStream which stores/loads content from a file.

Functions

Name	Description

Name	Description
~IGeoInputStream()	Deleting a stream should behave like a close operation.
GetPosition()	Return the position of the read/write pointer within the stream (prototype matches ftell)
IsEof()	Is the read pointer at the end of the file (as with feof, only returns true if you have read past end)
IsOk()	Tests if the stream is valid.
Read(T &)	Read a single object, returning true on success.
Read(void *, size_t, size_t)	Read data (prototype matches fread). Prefer to use the templated Read methods.
Read(TIter, TIter)	Read a collection of objects, returning true on success.
Read(T(&))	Read a fixed size array.
ReadImpl(T &, GeoStd::TrueType)	Read a single object, returning true on success.
ReadImpl(T &, GeoStd::FalseType)	Read a single object, returning true on success.
ReadToEnd()	Reads the stream to its end and returns the data as a char array.
SetPosition(Geo::u64)	Set the position of the read/write pointer within the stream (prototype matches fseek)

Deleting a stream should behave like a close operation.

virtual Geo::u64 Geo::IGeoInputStream::GetPosition

public: Geo::u64 GetPosition() const

Return the position of the read/write pointer within the stream (prototype matches ftell)

virtual bool Geo::IGeoInputStream::IsEof

public: bool IsEof() const

Is the read pointer at the end of the file (as with feof, only returns true if you have read past end)

virtual bool Geo::IGeoInputStream::IsOk

public: bool IsOk() const

Tests if the stream is valid.
