List of all members.

Detailed Description

Interface class, which encapsulate the reading from streams.

Overridables

virtual void ReadToLine (char *pt, int len)=0

Interface function to read exactly one line from a ASCII stream.

virtual int ReadToPointer (unsigned char *pt, int len)=0

Public Member Functions

int GetCurPos () const

Return the current position in the stream.

bool GetNextStreamChar (int &c)

Read next charcter from a stream.

int ReadBytes (unsigned char *pt, int len)

Read the specified number of bytes to the given pointer.

bool GetLineCr (XmString &line)

Read one line from a ASCII file to the given string.

bool GetLine (XmString &line)

Read one line from a ASCII file to the given string.

void Tie (XmStreamOut &outStream)

Member Function Documentation

void Tie ( XmStreamOut & outStream )

Tie the given out stream to this in stream.

virtual int ReadToPointer ( unsigned char * pt,

int len

) [private, pure virtual]

Interface function to read the specified number of bytes to a pointer.

Returns:
number of bytes effectively read.
