interface

private module subroutine from_string_large(self, string, status)

Initializes the bitset self treating string as a binary literal status may have the values: * success - if no problems were found, * alloc_fault - if allocation of the bitset failed * char_string_too_large_error - if string was too large, or * char_string_invalid_error - if string had an invalid character.

Arguments

private interface init_zero_large()

Arguments

interface

private module subroutine init_zero_large(self, bits, status)

Creates the bitset, self, of size bits, with all bits initialized to zero. bits must be non-negative. If an error occurs and status is absent then processing stops with an informative stop code. status will have one of the values; * success - if no problems were found, * alloc_fault - if memory allocation failed * array_size_invalid_error - if bits is either negative or larger than 64 with self of class bitset_64, or

Arguments

interface

private module subroutine input_large(self, unit, status)

Reads the components of the bitset, self, from the unformatted I/O unit, unit, assuming that the components were written using output. If an error occurs and status is absent then processing stops with an informative stop code. status has one of the values: * success - if no problem was found * alloc_fault - if it failed allocating memory for self, or * array_size_invalid_error if the bits(self) in unit is negative or greater than 64 for a bitset_64 input. * read_failure - if it failed during the reads from unit

Arguments

interface

private elemental module function none_large(self) result(none)

Returns .true. if none of the bits in self have the value 1.

Arguments

Return Value logical

interface

private elemental module subroutine not_large(self)

Sets the bits in self to their logical complement

Arguments

interface

private module subroutine output_large(self, unit, status)

Writes the components of the bitset, self, to the unformatted I/O unit, unit, in a unformatted sequence compatible with input. If status is absent an error results in an error stop with an informative stop code. If status is present it has the default value of success, or the value write_failure if the write failed.

Arguments

private interface read_bitset_string_large()

Arguments

private interface read_bitset_unit_large()

Arguments

interface

private module subroutine read_bitset_string_large(self, string, status)

Uses the bitset literal in the default character string, to define the bitset, self. The literal may be preceded by an an arbitrary sequence of blank characters. If status is absent an error results in an error stop with an informative stop code. If status is present it has one of the values * success - if no problems occurred, * alloc_fault - if allocation of memory for SELF failed, * array_size_invalid_error - ifbits(self)instringis greater than 64 for abitset_64, *char_string_invalid_error- if the bitset literal has an invalid character, *char_string_too_small_error - if the string ends before all the bits are read. * integer_overflow_error - if the bitset literal has a bits(self) value too large to be represented,

Arguments

interface

private module subroutine read_bitset_unit_large(self, unit, advance, status)

Uses the bitset literal at the current position in the formatted file with I/O unit, unit, to define the bitset, self. The literal may be preceded by an an arbitrary sequence of blank characters. If advance is present it must be either 'YES' or 'NO'. If absent it has the default value of 'YES' to determine whether advancing I/O occurs. If status is absent an error results in an error stop with an informative stop code. If status is present it has one of the values: * success - if no problem occurred, * alloc_fault - if allocation of self failed, * array_size_invalid_error - if bits(self) in the bitset literal is greater than 64 for a bitset_64, * char_string_invalid_error - if the read of the bitset literal found an invalid character, * eof_failure - if a read statement reached an end-of-file before completing the read of the bitset literal, * integer_overflow_error - if the bitset literal has a bits(self) value too large to be represented, * read_failure - if a read statement fails,

Arguments

private interface set_bit_large()

Arguments

private interface set_range_large()

Arguments

interface

private elemental module subroutine set_bit_large(self, pos)

Sets the value at the pos position in self, provided the position is valid. If the position is less than 0 or greater than bits(self)-1 then self is unchanged.

Arguments

interface

private pure module subroutine set_range_large(self, start_pos, stop_pos)

Sets all valid bits to 1 from the start_pos to the stop_pos positions in self. If stop_pos < start_pos no bits are changed. Positions outside the range 0 to bits(self)-1 are ignored.

Arguments

interface

private elemental module function test_large(self, pos) result(test)

Returns .true. if the pos position is set, .false. otherwise. If pos is negative or greater than bits(self) - 1 the result is .false..

Arguments

Return Value logical

interface

private module subroutine to_string_large(self, string, status)

Represents the value of self as a binary literal in string Status may have the values success or alloc_fault.

Arguments

interface

private elemental module function value_large(self, pos) result(value)

Returns 1 if the pos position is set, 0 otherwise. If pos is negative or greater than bits(set) - 1 the result is 0.

Arguments

Return Value integer

private interface write_bitset_string_large()

Arguments

private interface write_bitset_unit_large()

Arguments

interface

private module subroutine write_bitset_string_large(self, string, status)

Writes a bitset literal to the allocatable default character string, representing the individual bit values in the bitset_large, self. If status is absent an error results in an error stop with an informative stop code. If status is present it has the default value of success, or the valuealloc_fault` if allocation of the output string failed.

Arguments

interface

private module subroutine write_bitset_unit_large(self, unit, advance, status)

Writes a bitset literal to the I/O unit, unit, representing the individual bit values in the bitset, self. By default or if advance is present with the value 'YES', advancing output is used. If advance is present with the value 'NO', then the current record is not advanced by the write. If status is absent an error results in an error stop with an informative stop code. If status is present it has the default value of success, the value alloc_fault if allocation of the output string failed, or write_failure if the write statement outputting the literal failed.
