Detailed Description

Abstract base for every StringPipe.

A StringPipe transforms a given string into another one, for example a TrimPipe removes all left and right whitespace from a string. StringPipes can be chained ("linked list").

Note: You probably don't want to inherit from this class directly, unless you want to provide your own StringPipe::clone() method. If your subclass has a copy constructor, you can extend from hext::Cloneable<YourSubclass, hext::StringPipe> which provides a generic clone method.

Member Function Documentation

◆ append()

void hext::StringPipe::append ( std::unique_ptr< StringPipe pipe)

Append a StringPipe at the end of the chain.

◆ clone()

virtual std::unique_ptr<StringPipe> hext::StringPipe::clone ( ) const
pure virtual

◆ emplace()

template<typename StringPipeType , typename... Args>
void hext::StringPipe::emplace ( Args &&...  arg)

Construct a StringPipe at the end of the chain.

Definition at line 70 of file StringPipe.h.

◆ operator=() [1/2]

StringPipe& hext::StringPipe::operator= ( const StringPipe other)

◆ operator=() [2/2]

StringPipe& hext::StringPipe::operator= ( StringPipe &&  )

◆ pipe()

std::string hext::StringPipe::pipe ( std::string  str) const

Calls StringPipe::transform successively until the whole StringPipe chain was traversed.

The result of applying this StringPipe and every connected one to str.

◆ transform()

virtual std::string hext::StringPipe::transform ( std::string  str) const
pure virtual

Transforms str.

Note: Use StringPipe::pipe to apply all transformations in this chain.

Implemented in hext::TrimPipe, hext::RegexReplacePipe, hext::RegexPipe, hext::PrependPipe, hext::CollapseWsPipe, hext::CasePipe, and hext::AppendPipe.
