Fortran hash tables

Hash tables

Modern Fortran hash tables based on the function hashword in lookup3.c

Derived types

Five derived types are available:

Derived type	Data to be stored
table_char_t	Characters of a defined length. Trailing blanks are ignored.
table_int32_t	Integer scalars of 32 bits
table_real32_t	Real scalars of 32 bits
table_arrint32_t	Integer arrays of 32 bits
table_arrreal32_t	Real arrays of 32 bits

Public derived type methods

Each derived type contains these 7 public methods.

Method	Class	Description
add(element[, index, lnew])	Subroutine	Add the element element in the DT if not stored yet. The integer index (intent(out), optional) contains the index of the elements (between 1 and getfilled(). The logical lnew (intent(out), optional) is .true. if the element is not stored yet. Otherwise it is .false..
destroy()	Function	Reset all scalars and arrays
get(index)	Function	Returns the element stored corresponding to the index index.
getfilled()	Function	Returns the number of elements stored in the DT
getindex(element)	Function	Returns the index (between 1 and getfilled()) of the element element
getsize()	Function	Returns the size of the arrays that contains the stored elements
writetable(filename)	Subroutine	Writes to a file called filename all elements and corresponding index stored in the DT.
