Detailed Description

Private data for the Qore::StreamReader class.

Member Function Documentation

peekCheck()

int64 StreamReader::peekCheck ( ExceptionSink *  xsink )

inline

Peeks the next byte from the input stream.

Parameters

xsink

the exception sink

Returns

the next byte available to be read, -1 indicates an error (end of stream is treated as an error)

References ExceptionSink::raiseException().

read()

virtual DLLLOCAL qore_offset_t StreamReader::read ( ExceptionSink *  xsink, void *  dest, qore_size_t  limit, bool  require_all = true  )

inlinevirtual

Read data until a limit.

Parameters

xsink	exception sink
dest	destination buffer
limit	maximum amount of data to read
require_all	if true then throw an exception if the required amount of data cannot be read from the stream

Returns

amount of data read, -1 in case of error

Since

Qore 0.9

readBinary()

DLLLOCAL BinaryNode* StreamReader::readBinary ( int64  limit, ExceptionSink *  xsink  )

inline

Read binary data from the stream.

Parameters

limit	max amount of data to read; if equal to -1, all data will be read, if equal to 0, no data will be read
xsink	exception sink

Returns

Qore binary read from the stream

readLine()

DLLLOCAL QoreStringNode* StreamReader::readLine ( const QoreStringNode *  eol, bool  trim, ExceptionSink *  xsink  )

inline

Read one line.

Parameters

eol	end-of-line symbol, if missing and the character encoding is ASCII-compatible, then "\n", "\r", or "\r\n" are supported), otherwise if missing, and the character encoding is not ASCII-compatible, then "\n" is assumed
trim	whether to trim the EOL symbols
xsink	exception sink

Returns

Qore string read from the stream

readString()

DLLLOCAL QoreStringNode* StreamReader::readString ( int64  size, ExceptionSink *  xsink  )

inline

Read string data from the stream.

Parameters

size	max amount of data to read as a number of characters; if equal to -1, all data will be read, if equal to 0, no data will be read
xsink	exception sink

Returns

Qore string read from the stream
