chfl_property type

type chfl_property

A chfl_property holds data used in properties in chfl_frame, chfl_atom and chfl_residue.

A property is associated with a name and can contain data of various types: logical, real, string or 3 dimensional array (vector3d). The property kind is used to know which kind of data is stored in the property.

Type fields:
subroutine chfl_property%init(value[, status])

This is a generic subroutine for initialization of a property. It allocate memory which must be released with chfl_property%free().

value can be a real number, a logical value, a string (string) or an 3-dimensional array of real numbers.

Options:status [integer(chfl_status)] :: status code of the operation. If it is not CHFL_SUCCESS, use chfl_last_error() to learn more about the error.
function chfl_property%kind([status])

Get the property kind, a number indicating which type of value this property holds. The possible kinds are represented by integer of the chfl_property_kind kind.

chfl_property_kind [integer]

Kind parameter for the integer values describing chfl_property kinds.

CHFL_PROPERTY_BOOL [integer(chfl_property_kind)]

Kind used for logical (bool in C++) values.

CHFL_PROPERTY_DOUBLE [integer(chfl_property_kind)]

Kind used for real(real64) (double in C++) values.

CHFL_PROPERTY_STRING [integer(chfl_property_kind)]

Kind used for string (std::string in C++) values.

CHFL_PROPERTY_VECTOR3D [integer(chfl_property_kind)]

Kind used for real(real64), dimension(3) (vector3d in C++) values.

Return:integer (chfl_property_kind)
Options:status [integer(chfl_status)] :: status code of the operation. If it is not CHFL_SUCCESS, use chfl_last_error() to learn more about the error.
function chfl_property%bool([status])

Get the logical value stored in this property. If the property do not store a logical value, status will be CHFL_PROPERTY_ERROR.

Return:logical
Options:status [integer(chfl_status)] :: status code of the operation. If it is not CHFL_SUCCESS, use chfl_last_error() to learn more about the error.
function chfl_property%double([status])

Get the real value stored in this property. If the property do not store a real value, status will be CHFL_PROPERTY_ERROR.

Return:real [real64]
Options:status [integer(chfl_status)] :: status code of the operation. If it is not CHFL_SUCCESS, use chfl_last_error() to learn more about the error.
function chfl_property%string([status])

Get the string stored in this property. If the property do not store a string, status will be CHFL_PROPERTY_ERROR. If the string is longer than CHFL_STRING_LENGTH, it will be truncated.

Return:character (len=CHFL_STRING_LENGTH)
Options:status [integer(chfl_status)] :: status code of the operation. If it is not CHFL_SUCCESS, use chfl_last_error() to learn more about the error.
function chfl_property%vector3d([status])

Get the 3 dimensional array value stored in this property. If the property do not store an array, status will be CHFL_PROPERTY_ERROR.

Return:real [dimension(3), kind(real64)]
Options:status [integer(chfl_status)] :: status code of the operation. If it is not CHFL_SUCCESS, use chfl_last_error() to learn more about the error.
subroutine chfl_property%free()

Destroy a property, and free the associated memory
