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 231 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
