GzipInputStream() [1/4]

GzipInputStream ( const String &  file_name )

explicit

Constructor.

explicit

~GzipInputStream()

~GzipInputStream ( )

override

Destructor.

GzipInputStream ( const GzipInputStream &  stream )

private

Member Function Documentation

curPos()

XMLFilePos curPos ( ) const

inlineoverride

returns the current position in the file

Note

Implementation of the xerces-c input stream interface

References GzipInputStream::file_current_index_.

getContentType()

const XMLCh* getContentType ( ) const

override

returns 0

Note

Implementation of the xerces-c input stream interface

If no content type is provided for the data, 0 is returned (as is the case here, see xerces docs).

getIsOpen()

bool getIsOpen ( ) const

inline

returns true if file is open

References GzipInputStream::gzip_, and GzipIfstream::isOpen().

operator=()

GzipInputStream& operator= ( const GzipInputStream &  stream )

private

readBytes()

XMLSize_t readBytes ( XMLByte *const  to_fill, const XMLSize_t  max_to_read  )

override

writes bytes into buffer from file

Note

Implementation of the xerces-c input stream interface

Parameters

to_fill	is the buffer which is written to
max_to_read	is the size of the buffer

Returns

returns the number of bytes which were actually read
