## Detailed Description

This class implements an input stream which reads data from a string.

It supports seeking.

##

Library: wxBase
Category: Streams

## Public Member Functions
| wxStringInputStream (const wxString &s)
| Creates a new read-only stream using the specified string.
Public Member Functions inherited from wxInputStream
| wxInputStream ()
| Creates a dummy input stream.
virtual | ~wxInputStream ()
| Destructor.
virtual bool | CanRead () const
| Returns true if some data is available in the stream right now, so that calling Read() wouldn't block.
virtual bool | Eof () const
| Returns true after an attempt has been made to read past the end of the stream.
int | GetC ()
| Returns the first character in the input queue and removes it, blocking until it appears if necessary.
virtual size_t | LastRead () const
| Returns the last number of bytes read.
virtual char | Peek ()
| Returns the first character in the input queue without removing it.
virtual wxInputStream & | Read (void *buffer, size_t size)
| Reads the specified amount of bytes and stores the data in buffer.
wxInputStream & | Read (wxOutputStream &stream_out)
| Reads data from the input queue and stores it in the specified output stream.
bool | ReadAll (void *buffer, size_t size)
| Reads exactly the specified number of bytes into the buffer.
virtual wxFileOffset | SeekI (wxFileOffset pos, wxSeekMode mode=wxFromStart)
| Changes the stream current position.
virtual wxFileOffset | TellI () const
| Returns the current stream position or wxInvalidOffset if it's not available (e.g.
size_t | Ungetch (const void *buffer, size_t size)
| This function is only useful in read mode.
bool | Ungetch (char c)
| This function acts like the previous one except that it takes only one character: it is sometimes shorter to use than the generic function.
Public Member Functions inherited from wxStreamBase
| wxStreamBase ()
| Creates a dummy stream object.
virtual | ~wxStreamBase ()
| Destructor.
wxStreamError | GetLastError () const
| This function returns the last error.
virtual wxFileOffset | GetLength () const
| Returns the length of the stream in bytes.
virtual size_t | GetSize () const
| This function returns the size of the stream.
virtual bool | IsOk () const
| Returns true if no error occurred on the stream.
virtual bool | IsSeekable () const
| Returns true if the stream supports seeking to arbitrary offsets.
void | Reset (wxStreamError error=wxSTREAM_NO_ERROR)
| Resets the stream state.
bool | operator! () const
| Returns the opposite of IsOk().

## Constructor & Destructor Documentation

wxStringInputStream::wxStringInputStream | ( | const wxString & | s | ) |

Creates a new read-only stream using the specified string.

Note that the string is copied by the stream so if the original string is modified after using this constructor, changes to it are not reflected when reading from stream.
