Detailed Description

This class is a standard C++ stream class descendent for reading or writing streamed data to or from a PString class.

All of the standard stream I/O operators, manipulators etc will operate on the PStringStream class.

Constructor & Destructor Documentation

PStringStream::PStringStream ( )

Create a new, empty, string stream.

Data may be output to this stream, but attempts to input from it will return end of file.

The internal string is continually grown as required during output.

PStringStream::PStringStream ( PINDEX fixedBufferSize )

Create a new, empty, string stream of a fixed size.

Data may be output to this stream, but attempts to input from it will return end of file. When the fixed size is reached then no more data may be output to it.

PStringStream::PStringStream ( const PString & str )

Create a new string stream and initialise it to the provided value.

The string stream references the same string buffer as the str parameter until any output to the string stream is attempted. The reference is then broken and the instance of the string stream becomes a unique reference to a string buffer.

Parameters

str	Initial value for string stream.

PStringStream::PStringStream ( const char * cstr )

Create a new string stream and initialise it with the provided value.

The stream may be read or written from. Writes will append to the end of the string.

Parameters

cstr	Initial value for the string stream.

virtual PStringStream::~PStringStream ( )

virtual

Destroy the string stream, deleting the stream buffer.

Member Function Documentation

virtual void PStringStream::AssignContents ( const PContainer & c )

protectedvirtual

Copy the container contents.

This copies the contents from one reference to another.

No duplication of contents occurs, for instance if the container is an array, the pointer to the array memory is copied, not the array memory block itself.

This function will get called by the base assignment operator.

Reimplemented from PString.

Reimplemented in PHTML.

__inline void PStringStream::clear ( )

inline

virtual PINDEX PStringStream::GetLength ( ) const

virtual

Determine the length of the null terminated string.

This is different from PContainer::GetSize() which returns the amount of memory allocated to the string. This is often, though no necessarily, one larger than the length of the string.

Returns: length of the null terminated string.

Reimplemented from PString.

virtual PString& PStringStream::MakeEmpty ( )

virtual

Make the current string empty.

Reimplemented from PString.

PStringStream& PStringStream::operator= ( const PStringStream & strm )

Assign the string part of the stream to the current object.

The current instance then becomes another reference to the same string in the strm parameter.

This will reset the read pointer for input to the beginning of the string. Also, any data output to the string up until the asasignement will be lost.

Returns: reference to the current PStringStream object.

PStringStream& PStringStream::operator= ( const PString & str )

Assign the string to the current object.

The current instance then becomes another reference to the same string in the str parameter.

This will reset the read pointer for input to the beginning of the string. Also, any data output to the string up until the asasignement will be lost.

Returns: reference to the current PStringStream object.

Parameters

str	New string to assign.

PStringStream& PStringStream::operator= ( const char * cstr )

Assign the C string to the string stream.

The current instance then becomes a unique reference to a copy of the cstr parameter. The cstr parameter is typically a literal string, eg:


          myStr = "fred";

   This will reset the read pointer for input to the beginning of the
   string. Also, any data output to the string up until the asasignement
   will be lost.

   @return
   reference to the current PStringStream object.

Parameters

cstr	C string to assign.

PStringStream& PStringStream::operator= ( char ch )

Assign the character to the current object.

The current instance then becomes a unique reference to a copy of the character parameter. eg:


          myStr = 'A';

Returns: reference to the current PString object.

Parameters

ch	Character to assign.
