## Detailed Description

Attribute list used in IMessage and IStreamAttributes: Vst::IAttributeList.

- [host imp]
- [released: 3.0.0]
- [mandatory]

An attribute list associates values with a key (id: some predefined keys can be found in Predefined Preset Attributes).

## Member Function Documentation

## ◆ setInt()

virtual tresult setInt | ( | AttrID | id,
|  | int64 | value )
| pure virtual

Sets integer value.

Implemented in HostAttributeList.

## ◆ getInt()

virtual tresult getInt | ( | AttrID | id,
|  | int64 & | value )
| pure virtual

Gets integer value.

Implemented in HostAttributeList.

## ◆ setFloat()

virtual tresult setFloat | ( | AttrID | id,
|  | double | value )
| pure virtual

Sets float value.

Implemented in HostAttributeList.

## ◆ getFloat()

virtual tresult getFloat | ( | AttrID | id,
|  | double & | value )
| pure virtual

Gets float value.

Implemented in HostAttributeList.

## ◆ setString()

virtual tresult setString | ( | AttrID | id,
|  | const TChar * | string )
| pure virtual

Sets string value (UTF16) (must be null-terminated!).

Implemented in HostAttributeList.

## ◆ getString()

virtual tresult getString | ( | AttrID | id,
|  | TChar * | string,
|  | uint32 | sizeInBytes )
| pure virtual

Gets string value (UTF16).

Note that Size is in Byte, not the string Length! Do not forget to multiply the length by sizeof (TChar)!

Implemented in HostAttributeList.

## ◆ setBinary()

virtual tresult setBinary | ( | AttrID | id,
|  | const void * | data,
|  | uint32 | sizeInBytes )
| pure virtual

Sets binary data.

Implemented in HostAttributeList.

## ◆ getBinary()

virtual tresult getBinary | ( | AttrID | id,
|  | const void *& | data,
|  | uint32 & | sizeInBytes )
| pure virtual

Gets binary data.

Implemented in HostAttributeList.
