Detailed Description

Represents the Builder for an arbitrary user-defined mutable IDL union.

This example type represents the Builder type that rtiddsgen would generate for MyFlatUnion and allows creating a sample or a member of that type.

Union builders are similar to struct builders (see MyFlatMutableBuilder), except that they only allow adding/building one member.

"Add" and "build" functions automatically set the discriminator value that in the IDL definition selects that member. If more than one discriminator value selects a member, the add/build function allows picking one.

Member Typedef Documentation

◆ Offset

typedef MyFlatUnionOffset MyFlatUnionBuilder::Offset

The related offset type.

Constructor & Destructor Documentation

◆ MyFlatUnionBuilder()

MyFlatUnionBuilder::MyFlatUnionBuilder ( )

inline

Creates an invalid Builder.

Postcondition: !is_valid()

Note: Top-level builders are created with rti::flat::build_data(), and member builders are created with the corresponding build_<member> function.

Member Function Documentation

◆ finish()

Offset MyFlatUnionBuilder::finish ( )

Finishes building a member.

See also: MyMutableBuilder::finish()

◆ finish_sample()

MyFlatUnion * MyFlatUnionBuilder::finish_sample ( )

Finishes building a sample.

See also: MyMutableBuilder::finish_sample()

◆ add_my_primitive()

bool MyFlatUnionBuilder::add_my_primitive ( int32_t value )

Adds a primitive member.

This function automatically selects the discriminator 0, which corresponds to the member 'my_primitive' (see MyFlatUnion)

◆ build_my_mutable()

MyFlatMutableBuilder MyFlatUnionBuilder::build_my_mutable ( int32_t discriminator = 1 )

Builds a mutable-struct member.

Parameters

discriminator Allows selecting one of the possible discriminator values for this member: 1 or 2. This argument is optional: if not specified it selects the first 'case' label in the IDL definition (1).

Returns: The Builder to build this member

◆ add_my_final()

MyFlatFinal::Offset MyFlatUnionBuilder::add_my_final ( )

Adds a final-struct member.

Returns: The Offset to the member, which can be used to set its values.

This function automatically selects the discriminator value 3, which corresponds to the member 'my_final' (see MyFlatUnion).
