Detailed Description

Represents a single cusp of a SnapPea triangulation.

See the SnapPeaTriangulation class for further details.

Cusp objects should be considered temporary only. They are preserved if you change the fillings (via SnapPeaTriangulation::fill() or SnapPeaTriangulation::unfill()). However, if you change the SnapPea triangulation itself (e.g., via randomize()), then all cusp objects will be deleted and replaced with new ones (using fresh data re-fetched from the SnapPea kernel).

Member Function Documentation

◆ detail()

std::string regina::Output< Cusp , supportsUtf8 >::detail
inherited

Returns a detailed text representation of this object.

This text may span many lines, and should provide the user with all the information they could want. It should be human-readable, should not contain extremely long lines (which cause problems for users reading the output in a terminal), and should end with a final newline. There are no restrictions on the underlying character set.

Returns
a detailed text representation of this object.

◆ str()

std::string regina::Output< Cusp , supportsUtf8 >::str
inherited

Returns a short text representation of this object.

This text should be human-readable, should fit on a single line, and should not end with a newline. Where possible, it should use plain ASCII characters.

Python:\n In addition to str(), this is also used as the
Python "stringification" function str().
Returns
a short text representation of this object.

◆ utf8()

std::string regina::Output< Cusp , supportsUtf8 >::utf8
inherited

Returns a short text representation of this object using unicode characters.

Like str(), this text should be human-readable, should fit on a single line, and should not end with a newline. In addition, it may use unicode characters to make the output more pleasant to read. This string will be encoded in UTF-8.

Returns
a short text representation of this object.

◆ writeTextLong()

void regina::ShortOutput< Cusp , false >::writeTextLong ( std::ostream &  out) const
inlineinherited

A default implementation for detailed output.

This routine simply calls T::writeTextShort() and appends a final newline.

Python:\n Not present.
Parameters
outthe output stream to which to write.
