Class TAbstractSoundSourceNode

Unit

Declaration

type TAbstractSoundSourceNode = class(TAbstractTimeDependentNode)

Description

Base class for most (but not all) nodes that can emit audio data. We may introduce TSoundSourceFunctionality is needed to express exactly X3DSoundSourceObject.

Description

Methods

Public procedure CreateNode; override;

Create node fields and events.

Public class function ClassX3DType: String; override;

This item has no description. Showing description inherited from TX3DNode.ClassX3DType.

Node type name in VRML/X3D, for this class. Normal VRML/X3D node classes should override this to return something non-empty, and then X3DType automatically will return the same value.

Empty for classes that don't have a hardcoded VRML/X3D node name, like a special TX3DUnknownNode. Such special classes should override then X3DType to return actual non-empty name there.

You usually should call X3DType. The only use of this method is that it works on classes (it's "class function"), without needing at actual instance.

Properties

Public property FdDescription: TSFString read FFdDescription;

Internal wrapper for property Description. This wrapper API may change, we advise to access simpler Description instead, if it is defined (TODO: for now, some field types do not have a simpler counterpart).

Public property Description: String read GetDescription write SetDescription;

This item has no description.

Public property FdEnabled: TSFBool read FFdEnabled;

Internal wrapper for property Enabled. This wrapper API may change, we advise to access simpler Enabled instead, if it is defined (TODO: for now, some field types do not have a simpler counterpart).

Public property Enabled: Boolean read GetEnabled write SetEnabled;

This item has no description.

Public property FdGain: TSFFloat read FFdGain;

Internal wrapper for property Gain. This wrapper API may change, we advise to access simpler Gain instead, if it is defined (TODO: for now, some field types do not have a simpler counterpart).

Public property Gain: Single read GetGain write SetGain;

This item has no description.

Public property FdPitch: TSFFloat read FFdPitch;

Internal wrapper for property Pitch. This wrapper API may change, we advise to access simpler Pitch instead, if it is defined (TODO: for now, some field types do not have a simpler counterpart).

Public property Pitch: Single read GetPitch write SetPitch;

This item has no description.

Public property EventDuration_changed: TSFTimeEvent read FEventDuration_changed;

This item has no description.
