Adding new C++ wrappers
Description:
Added wrappers for H5Tencode to class DataType and H5Tdecode to
classes DataType and its subclasses.
// Creates a binary object description of this datatype.
void DataType::encode()
// Returns the decoded type from the binary object description.
virtual DataType* DataType::decode() const;
virtual DataType* ArrayType::decode() const;
virtual DataType* CompType::decode() const;
virtual DataType* DataType::decode() const;
virtual DataType* EnumType::decode() const;
virtual DataType* FloatType::decode() const;
virtual DataType* IntType::decode() const;
virtual DataType* StrType::decode() const;
virtual DataType* VarLenType::decode() const;
Platforms tested:
Linux/32 2.6 (jam)
Linux/64 (platypus)
Darwin (osx1010test)
