The visitor must be invocable as: Function(std::shared_ptr<Peer> const& peer);

Parameters

f	the invocable to call with every peer

◆ name()

std::string const & beast::PropertyStream::Source::name ( ) const

◆ add() [1/2]

void beast::PropertyStream::Source::add ( Source & source )

inherited

Add a child source.

Definition at line 174 of file beast_PropertyStream.cpp.

◆ add() [2/2]

template<class Derived>

Derived * beast::PropertyStream::Source::add ( Derived * child )

inherited

Add a child source by pointer.

The source pointer is returned so it can be used in ctor-initializers.

Definition at line 349 of file PropertyStream.h.

◆ remove() [3/3]

void beast::PropertyStream::Source::remove ( Source & child )

inherited

Remove a child source from this Source.

Definition at line 185 of file beast_PropertyStream.cpp.

◆ removeAll()

void beast::PropertyStream::Source::removeAll ( )

inherited

Definition at line 196 of file beast_PropertyStream.cpp.

◆ writeOne()

void beast::PropertyStream::Source::writeOne ( PropertyStream & stream )

inherited

Write only this Source to the stream.

Definition at line 209 of file beast_PropertyStream.cpp.

◆ write() [1/2]

void beast::PropertyStream::Source::write ( PropertyStream & stream )

inherited

write this source and all its children recursively to the stream.

Definition at line 216 of file beast_PropertyStream.cpp.

◆ write() [2/2]

void beast::PropertyStream::Source::write	(	PropertyStream &	stream,
		std::string const &	path )

inherited

Parse the path and write the corresponding Source and optional children.

If the source is found, it is written. If the wildcard character '*' exists as the last character in the path, then all the children are written recursively.

Definition at line 228 of file beast_PropertyStream.cpp.

◆ find()

std::pair< PropertyStream::Source *, bool > beast::PropertyStream::Source::find ( std::string path )

inherited

Parse the dot-delimited Source path and return the result.

The first value will be a pointer to the Source object corresponding to the given path. If no Source object exists, then the first value will be nullptr and the second value will be undefined. The second value is a boolean indicating whether or not the path string specifies the wildcard character '*' as the last character.

print statement examples "parent.child" prints child and all of its children "parent.child." start at the parent and print down to child "parent.grandchild" prints nothing- grandchild not direct descendent "parent.grandchild." starts at the parent and prints down to grandchild "parent.grandchild.*" starts at parent, print through grandchild children
