bool Arc::SecAttr::Export ( SecAttrFormat  format,
std::string &  val 
) const [virtual, inherited]

Convert internal structure into specified format.

Returns false if format is not supported/suitable for this attribute.

                                                              {

Here is the caller graph for this function:

bool Arc::SecAttr::Import ( SecAttrFormat  format,
const std::string &  val 
) [virtual, inherited]

Fills internal structure from external object of specified format.

Returns false if failed to do. The usage pattern for this method is not defined and it is provided only to make class symmetric. Hence it's implementation is not required yet.

Definition at line 32 of file SecAttr.cpp.

                                                              {
  XMLNode x(val);
  if(!x) return false;
  return Import(format,x);
}
bool Arc::SecAttr::Import ( SecAttrFormat  format,
XMLNode  val 
) [virtual, inherited]

Reimplemented in Arc::MultiSecAttr.

Definition at line 38 of file SecAttr.cpp.

                                           {
  return false;
}
Arc::HTTPSecAttr::operator bool ( void  ) const [virtual]

This function should return false if the value is to be considered null, e.g.

if it hasn't been set or initialized. In other cases it should return true.

Reimplemented from Arc::SecAttr.

Definition at line 75 of file MCCHTTP.cpp.

                                     {
  return true;
}
bool Arc::SecAttr::operator!= ( const SecAttr b) const [inline, inherited]

This is a convenience function to allow the usage of "not equal" conditions and need not be overridden.

Definition at line 54 of file SecAttr.h.

{ return !equal(b); };

Here is the call graph for this function:

bool Arc::SecAttr::operator== ( const SecAttr b) const [inline, inherited]

This function should (in inheriting classes) return true if this and b are considered to represent same content.

Identifying and restricting the type of b should be done using dynamic_cast operations. Currently it is not defined how comparison methods to be used. Hence their implementation is not required.

Definition at line 51 of file SecAttr.h.

{ return equal(b); };
