NormalTypeInstance type

Methods

.(obj:NormalTypeInstance, field:Str)

Get NormalType (a type that is typically defined by user) instance field. Throws FieldNotFound.

Automatically called by NGS for syntax

obj.field

Returns

Any

Example

type T; t=T(); t.x=1; t.x  # 1

.=(obj:NormalTypeInstance, field:Str, v:Any)

Set Normal type (a type that is typically defined by user) instance field

Automatically called by NGS for syntax

obj.field = v

Returns

v

Example

type T; t=T(); t.x=1

::(nti:NormalTypeInstance, k:Any) Source: stdlib.ngs:103

Get NormalType object field. Useful when calling method stored in an field.

Example

myobj::method_in_field(arg)  # calls method stored in myobj.method_in_field
(myobj.method_in_field)(arg) # calls method stored in myobj.method_in_field
myobj.method_in_field(arg)   # calls global "method_in_field"

::=(nti:NormalTypeInstance, k:Any, v:Any) Source: stdlib.ngs:111

Set NormalType object field. It's implemented to complete the :: operator. There is no particular use case.

==(a:NormalTypeInstance, b:NormalTypeInstance) Source: stdlib.ngs:1082

Equality test for normal type instances: must be of same type and have same fields and their values

Returns

Bool

Example

type T
t1 = T()
t1.a = 1
t2 = T()
t2.a = 1
echo(t1 == t2)  # Outputs: true

copy(nti:NormalTypeInstance) Source: stdlib.ngs:1097

Make shallow copy of an object

dflt(i:NormalTypeInstance, k:Any, v:Any) Source: stdlib.ngs:1052

Set object field if it's not already set

Returns

Field value, the already-existed or new.

Example

my_something.dflt(k, []).push(elt)

Hash(obj:NormalTypeInstance)

Get all fields and their values as key-value pairs in the resulting Hash.

Returns

Hash

Example

(1..10).Hash()  # Hash {start=1, end=10, step=1}

in(field:Str, obj:NormalTypeInstance)

Check whether NormalType (a type that is typically defined by user) instance has the given field.

Automatically called by NGS for syntax

field in obj

Returns

Bool

Example

type T; t=T(); t.x=1; "x" in t  # true

Str(i:NormalTypeInstance) Source: stdlib.ngs:1033

String representation of normal type instance i Normal type is a user defined type. In addition some types defined by NGS are also normal types.

Returns

"<TYPE_NAME field1=val1 field2=val2 ...>"

Example

{
  type T
  # nti - Normal type instance
  nti = T()
  nti.a = 1
  nti.b = 2
  echo(Str(nti)) # <T a=1 b=2>
}
