Detailed Description

As the ELM String class is immutable, the big building of strings may have a prohibitive cost. Instead, this class provides an economic way of concatenating strings.

Constructor & Destructor Documentation

StringBuffer()

StringBuffer ( int  capacity = 64, int  increment = 32  )

inline

Build a new string buffer.

Parameters

capacity	Initial capacity of the buffer.
increment	Incrementation size when buffer is enlarged.

Member Function Documentation

copyString()

String copyString ( )

inline

References BlockOutStream::block(), and BlockOutStream::size().

length()

int length ( void  ) const

inline

Get the length of the string stored in the buffer.

Returns

String length.

References BlockOutStream::size().

Referenced by ProcessBuilder::run(), and StringBuffer::toString().

reset()

void reset ( void  )

inline

Remove all characters from the string buffer.

References BlockOutStream::clear().

Referenced by VarExpander::write().

stream()

io::OutStream & stream ( void  )

inline

Get the an output stream to write to the string buffer.

Returns

Stream to the string buffer.

Referenced by VarExpander::expand(), and Saver::Saver().

toCString()

CString toCString ( )

inline

References BlockOutStream::block(), and BlockOutStream::write().

toString()

String toString ( )

inline

Convert the buffer to a string. The string buffer must no more be used after this call.

Returns

String contained in the buffer.
