Function Documentation

◆ AppendBytes()

template<typename T >
void mfem::bin_io::AppendBytes ( std::vector< char > &  vec,
const T &  val 
)

Append the binary representation of val to the byte buffer vec.

Definition at line 55 of file binaryio.hpp.

◆ DecodeBase64()

void mfem::bin_io::DecodeBase64 ( const char *  src,
size_t  len,
std::vector< char > &  buf 
)

Decode len base-64 encoded characters in the buffer src, and store the resulting decoded data in buf. buf will be resized as needed.

Definition at line 74 of file binaryio.cpp.

◆ NumBase64Chars()

size_t mfem::bin_io::NumBase64Chars ( size_t  nbytes)

Return the number of characters needed to encode nbytes in base-64.

This is equal to 4*nbytes/3, rounded up to the nearest multiple of 4.

Definition at line 103 of file binaryio.cpp.

◆ read() [1/2]

template<typename T >
T mfem::bin_io::read ( std::istream &  is)
inline

Read a value from the stream and return it.

Definition at line 37 of file binaryio.hpp.

◆ read() [2/2]

template<typename T >
T mfem::bin_io::read ( const char *  buf)
inline

Read a value of type T from a binary buffer and return it.

Definition at line 46 of file binaryio.hpp.

◆ write()

template<typename T >
void mfem::bin_io::write ( std::ostream &  os,
value 
)
inline

Write 'value' to stream.

Definition at line 30 of file binaryio.hpp.

◆ WriteBase64()

void mfem::bin_io::WriteBase64 ( std::ostream &  out,
const void *  bytes,
size_t  nbytes 
)

Given a buffer bytes of length nbytes, encode the data in base-64 format, and write the encoded data to the output stream out.
