virtual bool read()
Read data into a local buffer.
Holds an Internet address (URL).
virtual bool read_p()
Has this variable been read?
virtual void print_val(FILE *out, string space="", bool print_decl_p=true)
Prints the value of the variable.
abstract base class used to unmarshall/deserialize dap data objects
virtual void print_decl(FILE *out, string space=" ", bool print_semi=true, bool constraint_info=false, bool constrained=false)
Print an ASCII representation of the variable structure.
virtual unsigned int val2buf(void *val, bool reuse=false)
virtual unsigned int width(bool constrained=false) const
How many bytes does this use Return the number of bytes of storage this variable uses. For scalar types, this is pretty simple (an int32 uses 4 bytes, etc.). For arrays and Constructors, it is a bit more complex. Note that a scalar String variable uses sizeof(String*) bytes, not the length of the string. In other words, the value returned is independent of the type. Also note width() of a String array returns the number of elements in the array times sizeof(String*). That is, each different array size is a different data type.
