Detailed Description

An adapter class for C++ standard input streams.

Constructor & Destructor Documentation

inputStreamAdapter()

inputStreamAdapter

(

std::istream &

is

)

Parameters

is	input stream to wrap

Member Function Documentation

eof()

bool eof ( ) const

virtual

Test for end of stream (no more data to read).

Returns

true if we have reached the end of stream, false otherwise

Implements inputStream.

getPosition()

size_t getPosition ( ) const

virtual

Returns the current position in this stream.

Returns

the offset from the beginning of the stream, in bytes, at which the next read occurs

Implements seekableInputStream.

read()

size_t read ( byte_t *const  data, const size_t  count  )

virtual

Read data from the stream.

Parameters

data	will receive the data read
count	maximum number of bytes to read

Returns

number of bytes read

Implements inputStream.

Referenced by inputStreamAdapter::reset().

reset()

void reset ( )

virtual

Set the read pointer to the beginning of the stream.

Warning

WARNING: this may not work for all stream types.

Implements inputStream.

References inputStreamAdapter::read().

seek()

void seek ( const size_t  pos )

virtual

Sets the position, measured from the beginning of this stream, at which the next read occurs.

Parameters

pos	the offset position, measured in bytes from the beginning of the stream, at which to set the stream pointer.

Implements seekableInputStream.

skip()

size_t skip ( const size_t  count )

virtual

Skip a number of bytes.

Parameters

count

maximum number of bytes to ignore

Returns

number of bytes skipped

Implements inputStream.
