Detailed Description

Node representing a string value.

Member Function Documentation

◆ create()

cvb.gevserver.StringNode create ( str  name,
int   namespace = cvb.gevserver.NameSpace.Standard 
)

Creates a new string node.

The node can be created using only the name with namespace or using the name only and an extra namespace parameter. You must add this node to a node map before most operations are possible.

Parameters

name : str Node name with or without namespace prefix. If the name does not contain a namespace prefix and no namespace is specified separately, cvb.gevserver.NameSpace.Custom is used.

namespace : int Namespace to place the node in if not part of the name (see cvb.gevserver.NameSpace).

Returns

cvb.gevserver.StringNode The requested node.

Property Documentation

◆ value_config_as_node

value_config_as_node = property
static

cvb.gevserver.StringNode: Gets or sets a node that determines this node's value.

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

◆ value_config_as_string

value_config_as_string = property
static

str: Gets or sets a string that determines this node's value.

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