Detailed Description

This module implements a simple hash table for string valued keys and integer values using the C++ STL unordered_map container.

Data Types
type	sphash_iterator_t
type	sphash_t
interface	sphash_value_t

Functions/Subroutines
type(sphash_value_t) function, pointer	sphash_value_constructor (value, clone)
subroutine	sphash_value_finalize (this)
class(*) function, pointer	sphash_value_get (this)
subroutine, public	sphash_init (h)
	Initialize a hash table h with size entries. Since we use separate chaining, the number of entries in the hash table is in principle, unlimited. We take the smallest prime number as table size that is greater or equal than the requested size, to reduce collisions. More...
logical function	sphash_is_associated (this)
	Check if the sphash attribute, map, is associated. More...
subroutine, public	sphash_end (h)
	Free a hash table. More...
subroutine, public	sphash_insert (h, key, val, clone)
	Insert a (key, val) pair into the hash table h. If clone=.true., the object will be copied. More...
class(*) function, pointer, public	sphash_lookup (h, key, found)
	Look up a value in the hash table h. If found is present, it indicates if key could be found in the table. If found = .false., the return value of iihash_lookup is meaningless (and essentially undefined). More...
subroutine	sphash_iterator_start (this, h)
logical function	sphash_iterator_has_next (this)
class(*) function, pointer	sphash_iterator_get_next (this)

Function/Subroutine Documentation

sphash_value_constructor()

type(sphash_value_t) function, pointer sphash_oct_m::sphash_value_constructor ( class(*), intent(in), target  value, logical, intent(in), optional  clone  )

sphash_value_finalize()

subroutine sphash_oct_m::sphash_value_finalize ( type(sphash_value_t)  this )

private

Definition at line 195 of file sphash.F90.

sphash_value_get()

class(*) function, pointer sphash_oct_m::sphash_value_get ( class(sphash_value_t), intent(in)  this )

private

Definition at line 210 of file sphash.F90.

sphash_init()

subroutine, public sphash_oct_m::sphash_init

(

type(sphash_t), intent(out)

h

)

Initialize a hash table h with size entries. Since we use separate chaining, the number of entries in the hash table is in principle, unlimited. We take the smallest prime number as table size that is greater or equal than the requested size, to reduce collisions.

sphash_is_associated()

logical function sphash_oct_m::sphash_is_associated

(

class(sphash_t), intent(in)

this

)

Check if the sphash attribute, map, is associated.

Definition at line 240 of file sphash.F90.

sphash_end()

subroutine, public sphash_oct_m::sphash_end

(

type(sphash_t), intent(inout)

h

)

Free a hash table.

Definition at line 248 of file sphash.F90.

sphash_insert()

subroutine, public sphash_oct_m::sphash_insert	(	type(sphash_t), intent(inout)	h,
		character(len=*), intent(in)	key,
		class(*), intent(in), target	val,
		logical, intent(in), optional	clone
	)

Insert a (key, val) pair into the hash table h. If clone=.true., the object will be copied.

Definition at line 292 of file sphash.F90.

sphash_lookup()

class(*) function, pointer, public sphash_oct_m::sphash_lookup	(	type(sphash_t), intent(in)	h,
		character(len=*), intent(in)	key,
		logical, intent(out), optional	found
	)

Look up a value in the hash table h. If found is present, it indicates if key could be found in the table. If found = .false., the return value of iihash_lookup is meaningless (and essentially undefined).

Definition at line 324 of file sphash.F90.

sphash_iterator_start()

subroutine sphash_oct_m::sphash_iterator_start	(	class(sphash_iterator_t), intent(inout)	this,
		class(sphash_t), intent(in)	h
	)

Definition at line 365 of file sphash.F90.

sphash_iterator_has_next()

logical function sphash_oct_m::sphash_iterator_has_next

(

class(sphash_iterator_t), intent(in)

this

)

Definition at line 386 of file sphash.F90.

sphash_iterator_get_next()

class(*) function, pointer sphash_oct_m::sphash_iterator_get_next

(

class(sphash_iterator_t), intent(inout)

this

)
