Constructor & Destructor Documentation

gsReadFile() [1/4]

template<class T = real_t>

gsReadFile ( std::string const &  fn )

inline

Opens a file and reads an object into a smartpointer (uPtr).

This is used in conjuction with cast operators and depends on the type of object.

For gsBasis there exists a cast opterator to std::vector<gsBasis<T>::uPtr>.

If read fails, value inside smartpointer is null. Example of usage:

gsFunctionExpr<>::uPtr expr;
if(expr = gsReadFile<real_t>("/path/to/file.xml"))
    gsInfo << *expr;

Parameters

fn	filename string

gsReadFile() [2/4]

template<class T = real_t>

gsReadFile ( std::string const &  fn, index_t  id  )

inline

Opens a file and reads an object into a smartpointer (uPtr).

This is used in conjuction with cast operators and depends on the type of object.

For gsBasis there exists a cast opterator to std::vector<gsBasis<T>::uPtr>.

If read fails, value inside smartpointer is null. Example of usage:

gsFunctionExpr<>::uPtr expr;
if(expr = gsReadFile<real_t>("/path/to/file.xml"))
    gsInfo << *expr;

Parameters

fn	filename string
id

gsReadFile() [3/4]

template<class T = real_t>

template<class Obj >

gsReadFile ( std::string const &  fn, Obj &  result  )

inline

Opens a file and reads an object into result.

Example of usage:

std::string filename = "/path/to/file.xml";
gsMultiPatch<> MP;
gsReadFile<>(filenane, MP);

Exceptions

std::runtime_error

Error reading file.

Parameters

[in]	fn	filename string
[out]	result	object to read into

gsReadFile() [4/4]

template<class T = real_t>

gsReadFile ( std::string const &  fn, gsMultiPatch< T > &  result  )

inline

Opens a file and reads a gsMultiPatch object into result.

Example of usage:

std::string filename = "/path/to/file.xml";
gsMultiPatch<> MP;
gsReadFile<>(filenane, MP);

Exceptions

std::runtime_error

Error reading file.

Parameters

[in]	fn	filename string
[out]	result	gsMultiPatch object to read into
