var MapConverter *TMapConverter = &TMapConverter{}

func (*TMapConverter) ToMap 

func (c *TMapConverter) ToMap(value interface{}) map[string]interface{}

Converts value into map object or returns empty map when conversion is not possible. Parameters: "value" - the value to convert Returns: map object or empty map when conversion is not supported.

func (*TMapConverter) ToMapWithDefault 

func (c *TMapConverter) ToMapWithDefault(value interface{}, defaultValue map[string]interface{}) map[string]interface{}

Converts value into map object or returns default map when conversion is not possible. Parameters: 

"value" - the value to convert
"defaultValue" - the default value.

Returns: map object or default map when conversion is not supported.

func (*TMapConverter) ToNullableMap 

func (c *TMapConverter) ToNullableMap(value interface{}) *map[string]interface{}

Converts value into map object or returns null when conversion is not possible. Parameters: "value" - the value to convert Returns: map object or null when conversion is not supported.

type TStringConverter 

type TStringConverter struct{}

Converts arbitrary values into strings using extended conversion rules: - Numbers: are converted with '.' as decimal point - DateTime: using ISO format - Boolean: "true" for true and "false" for false - Arrays: as comma-separated list - Other objects: using toString() method

Example: 

var value1 = convert.StringConverter.ToString(123.456)
var value2 = convert.StringConverter.ToString(true)
var value3 = convert.StringConverter.ToString(time.Now())
var value4 = convert.StringConverter.ToString([...]int{1, 2, 3})
fmt.Println(value1) // 123.456
fmt.Println(value2) // true
fmt.Println(value3) // 2019-08-20T23:54:47+03:00
fmt.Println(value4) // 1,2,3

var StringConverter *TStringConverter = &TStringConverter{}

func (*TStringConverter) ToNullableString 

func (c *TStringConverter) ToNullableString(value interface{}) *string

Converts value into string or returns null when value is null. Parameters: "value" - the value to convert Returns: string value or null when value is null.

func (*TStringConverter) ToString 

func (c *TStringConverter) ToString(value interface{}) string

Converts value into string or returns "" when value is null. Parameters: "value" - the value to convert Returns: string value or "" when value is null.

func (*TStringConverter) ToStringWithDefault 

func (c *TStringConverter) ToStringWithDefault(value interface{}, defaultValue string) string

Converts value into string or returns default when value is null. Parameters: 

"value" - the value to convert.
"defaultValue" - the default value.

Returns: string value or default when value is null.

type TTypeConverter 

type TTypeConverter struct{}

Converts arbitrary values into objects specific by TypeCodes. For each TypeCode this class calls corresponding converter which applies extended conversion rules to convert the values.

Example: 

value1 := convert.TypeConverter.ToType(convert.Integer, "123.456")
value2 := convert.TypeConverter.ToType(convert.DateTime, 123)
value3 := convert.TypeConverter.ToType(convert.Boolean, "F")
fmt.Println(value1) // 123
fmt.Println(value2) // 1970-01-01 02:02:03 +0200 EET
fmt.Println(value3) // false

var TypeConverter *TTypeConverter = &TTypeConverter{}

func (*TTypeConverter) ToNullableType 

func (c *TTypeConverter) ToNullableType(typ TypeCode, value interface{}) interface{}

Converts value into an object type specified by Type Code or returns null when conversion is not possible. Parameters: 

"typ" - the TypeCode for the data type.
"value" - the value to convert.

Returns: object value of type corresponding to TypeCode, or null when conversion is not supported.

func (*TTypeConverter) ToString 

func (c *TTypeConverter) ToString(typ TypeCode) string

Converts a TypeCode into its string name. Parameters: "typ" - the TypeCode to convert into a string. Returns: the name of the TypeCode passed as a string value.

func (*TTypeConverter) ToType 

func (c *TTypeConverter) ToType(typ TypeCode, value interface{}) interface{}

Converts value into an object type specified by Type Code or returns default value when conversion is not possible. Parameters: 

"typ" - the TypeCode for the data type into which 'value' is to be converted.
"value" - the value to convert.

Returns: object value of type corresponding to TypeCode, or default value when conversion is not supported

func (*TTypeConverter) ToTypeCode 

func (c *TTypeConverter) ToTypeCode(value interface{}) TypeCode

Gets TypeCode for specific value. Parameters: "value" - value whose TypeCode is to be resolved. Returns: the TypeCode that corresponds to the passed object's type.

func (*TTypeConverter) ToTypeWithDefault 

func (c *TTypeConverter) ToTypeWithDefault(typ TypeCode, value interface{}, defaultValue interface{}) interface{}

Converts value into an object type specified by Type Code or returns default value when conversion is not possible. Parameters: 

"typ" - the TypeCode for the data type into which 'value' is to be converted.
"value" - the value to convert.
"defaultValue" - the default value to return if conversion is not possible
(returns null).

Returns: object value of type corresponding to TypeCode, or default value when conversion is not supported

type TypeCode 

type TypeCode int

Codes for the data types that can be converted using TypeConverter.
