Member Enumeration Documentation

enum FieldType

Describes the possible types of a Data Form Field.

Enumerator:
TypeBoolean 

The field enables an entity to gather or provide an either-or choice between two options. The default value is "false".

TypeFixed 

The field is intended for data description (e.g., human-readable text such as "section" headers) rather than data gathering or provision. The <value/> child SHOULD NOT contain newlines (the \n and \r characters); instead an application SHOULD generate multiple fixed fields, each with one <value/> child.

TypeHidden 

The field is not shown to the entity providing information, but instead is returned with the form.

TypeJidMulti 

The field enables an entity to gather or provide multiple Jabber IDs.

TypeJidSingle 

The field enables an entity to gather or provide a single Jabber ID.

TypeListMulti 

The field enables an entity to gather or provide one or more options from among many.

TypeListSingle 

The field enables an entity to gather or provide one option from among many.

TypeTextMulti 

The field enables an entity to gather or provide multiple lines of text.

TypeTextPrivate 

The field enables an entity to gather or provide a single line or word of text, which shall be obscured in an interface (e.g., *****).

TypeTextSingle 

The field enables an entity to gather or provide a single line or word of text, which may be shown in an interface. This field type is the default and MUST be assumed if an entity receives a field type it does not understand.

TypeNone 

The field is child of either a <reported> or <item> element or has no type attribute.

TypeInvalid 

The field is invalid. Only possible if the field was created from a Tag not correctly describing a Data Form Field.

Member Function Documentation

void addOption ( const std::string &  label,
const std::string &  value 
) [inline]

Adds a single option to the list of options.

Parameters:
label The label of the option.

Definition at line 146 of file dataformfield.h.

void addValue ( const std::string &  value  )  [inline]

Adds a single value to the list of values.

Parameters:
value The value to add.

Definition at line 214 of file dataformfield.h.

const std::string& description (  )  const [inline]

Use this function to retrieve the description of this field.

Returns:
The description of this field

Definition at line 177 of file dataformfield.h.

const std::string& label (  )  const [inline]

Use this function to retrieve the describing label of this field.

Returns:
The describing label of this field.

Definition at line 165 of file dataformfield.h.

const std::string& name (  )  const [inline]

Use this function to retrieve the name of the field (the content of the 'var' attribute).

Returns:
The name of the field.

Definition at line 122 of file dataformfield.h.

operator bool (  )  const [inline]

Converts to true if the FormBase is valid, false otherwise.

Definition at line 225 of file dataformfield.h.

const StringMultiMap& options (  )  const [inline]

Use this function to retrieve the optional values of a field.

Returns:
The options of a field.

Definition at line 108 of file dataformfield.h.

bool required (  )  const [inline]

Use this function to determine whether or not this field is required.

Returns:
Whether or not this field is required.

Definition at line 153 of file dataformfield.h.

void setDescription ( const std::string &  desc  )  [inline]

Use this function to set the description of this field.

Parameters:
desc The description of this field.

Definition at line 183 of file dataformfield.h.

void setLabel ( const std::string &  label  )  [inline]

Use this function to set the describing label of this field.

Parameters:
label The describing label of this field.

Definition at line 171 of file dataformfield.h.

void setName ( const std::string &  name  )  [inline]

Sets the name (the content of the 'var' attribute) of the field. The name identifies the field uniquely in the form.

Parameters:
name The new name of the field.
Note:
Fields of type other than 'fixed' MUST have a name, if it is 'fixed', it MAY.

Definition at line 130 of file dataformfield.h.

void setOptions ( const StringMultiMap options  )  [inline]

Use this function to set the optional values of the field. The key of the map will be used as the label of the option, while the value will be used as ... the value. ;)

Parameters:
options The optional values of a list* or *multi type of field.

Definition at line 138 of file dataformfield.h.

void setRequired ( bool  required  )  [inline]

Use this field to set this field to be required.

Parameters:
required Whether or not this field is required.

Definition at line 159 of file dataformfield.h.

void setValue ( const std::string &  value  )  [inline]

Use this function to set the value of this field.

Parameters:
value The new value of this field.

Definition at line 195 of file dataformfield.h.

void setValues ( const StringList values  )  [inline]

Use this function to set multiple values of this field, if it is of type 'text-multi'. If its not, use setValue() instead.

Parameters:
values The new values of this field.

Definition at line 208 of file dataformfield.h.

Tag * tag (  )  const [virtual]

Use this function to create a Tag representation of the form field. This is usually called by DataForm.

Returns:
A Tag hierarchically describing the form field, or NULL if the field is invalid (i.e. created from a Tag not correctly describing a Data Form Field).

Definition at line 88 of file dataformfield.cpp.
