Detailed Description

describes a data type based on a hashdecl

Member Function Documentation

acceptsValue()

auto DataProvider::AbstractDataField::acceptsValue

(

auto

value

)

returns the value if the value can be assigned to the type

Parameters

value

the value to assign to the type

Returns

the value to be assigned; can be converted by the type

getInputInfo()

hash<DataFieldInfo> DataProvider::AbstractDataField::getInputInfo

(

)

returns information about the field as an input field

the default_value key is not returned, and the type key returns only input information

getOrNothingType()

AbstractDataField DataProvider::AbstractDataField::getOrNothingType

(

)

returns a field with an "or nothing" type equivalent to the current type

The base class method returns the same field; this method must be overridden in child classes to return a field with a usable "or nothing" type

Returns

a field with an "or nothing" type equivalent to the current type

getSoftType()

AbstractDataField DataProvider::AbstractDataField::getSoftType

(

)

returns a field with a "soft" type equivalent to the current type

The base class method returns the same field; this method must be overridden in child classes to return a field with a usable "soft" type

Returns

a field with a "soft" type equivalent to the current type

setOption()

DataProvider::AbstractDataField::setOption	(	string	opt,
		auto	value
	)

sets the given option on the field's type

Parameters

opt	the option to set
value	the value to set

Exceptions

TYPE-OPTION-ERROR

invalid option or invalid option type

setOptions()

DataProvider::AbstractDataField::setOptions

(

hash< auto >

options

)

sets the given options on the field's type

Parameters

options

a hash of options, if any options match supported options for this type, they are set

Exceptions

TYPE-OPTION-ERROR

option value has an invalid type

Member Data Documentation

allowed_values_map

hash<string, bool> DataProvider::AbstractDataField::allowed_values_map

private

for enum fields; allowed values

only supported for types that convert to a string
