◆ AccessMode()

GenApi::AccessMode AccessMode ( ) const

inlineoverridevirtual

Gets the access mode by querying all ValueConfigs for it.

Returns: The effective access mode.

Reimplemented from Node.

◆ CacheMode()

GenApi::CacheMode CacheMode ( ) const

inlineoverridevirtual

Returns: The effective cache mode.

Reimplemented from Node.

◆ Create() [1/2]

static FloatNodePtr Create ( const String & name )

inlinestatic

Creates a new FloatNode with the given name .

If the name does not contain a namespace prefix the Namespace::Custom is used.

You must add this node to a NodeMap before most operations are possible!

Parameters

name	Name with optional namespace prefix.

◆ Create() [2/2]

static FloatNodePtr Create	(	const String &	name,
		const GevServer::Namespace &	nameSpace
	)

inlinestatic

Creates a new FloatNode with the given name and nameSpace .

You must add this node to a NodeMap before most operations are possible!

Parameters

name	Node name without namespace prefix.
nameSpace	Namespace to place the node in.

void SetUnit ( const String & unit )

inline

Sets the unit of this node's value.

Parameters

[in] unit of this node as text.

Exceptions

Any	exception derived from std::exception including CvbException.

◆ SetValueConfig()

void SetValueConfig ( const T & )

inline

Sets the value configuration of this float node.

This defines whether this float stores the value or the value is referenced to another node.

Set operation is only possible as long as the GevServer is in GevServer::State::Configuration GevServer::State.

◆ Unit()

String Unit ( ) const

inline

Gets the unit of this node's value.

Returns: Unit of this node as text.

Exceptions

Any	exception derived from std::exception including CvbException.
