get_table_extdouble_v Subroutine

private subroutine get_table_extdouble_v(val, ErrCode, L, thandle, key, pos, default)

This routine obtains a vectorial quantity with fixed length from a Lua table as a whole.

It is intented to ease the reading of vectors on the Fortran side by capsulating the parsing of the Lua table internally. Components which are not found are filled with the data given in the default vector. For each component an error code will be returned to indicate the success when reading it. If the vector is not defined at all, all components will be indicated as non-existent. Components, which are neither defined in the Lua script, nor in the default will be marked with the aoterr_Fatal flag.

Arguments

Type IntentOptional Attributes Name
real(kind=xdble_k), intent(out) :: val(:)

Vector read from the Lua table.
integer, intent(out) :: ErrCode(:)

Error code describing problems encountered in each of the components. This array has to have the same length as val.
type(flu_State) :: L
integer, intent(in), optional :: thandle
character(len=*), intent(in), optional :: key

Name of the variable (vector) to read.
integer, intent(in), optional :: pos

Position of the (vector) to read.
real(kind=xdble_k), intent(in), optional :: default(:)

A default vector to use, if no proper definition is found. Components will be filled with the help of this default definition.
