Detailed Description

The SoConcatenate class is used to concatenate several inputs into one output.

Takes all the values from the 10 input multivalue fields in turn and concatenates them into the multivalue output.

Note that this engine's output field deviates a little from the "standard" output mechanism of the majority of engine classes: the SoConcatenate::output is not a permanent SoEngineOutput instance, but a pointer to a SoEngineOutput instance. The reason for this is that it is necessary to allocate the output field dynamically to make it match what the SoConcatenate::input is connected to since the type of the SoConcatenate::output always should be the same as the type of the SoConcatenate::input.

The file format for this field is a bit special. Note the leading type specification, which is not necessary for most other field types:

Concatenate {
  type <multivaluefieldtype>
  [...fields...]
}

Constructor & Destructor Documentation

◆ SoConcatenate()

SoConcatenate::SoConcatenate ( SoType type)

Constructor. The type of the input/output is specified in type.

Member Function Documentation

◆ getFieldData()

virtual const SoFieldData * SoConcatenate::getFieldData ( void ) const
virtual

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from SoFieldContainer.

◆ getOutputData()

virtual const SoEngineOutputData * SoConcatenate::getOutputData ( void ) const
virtual

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Implements SoEngine.

◆ getTypeId()

virtual SoType SoConcatenate::getTypeId ( void ) const
virtual

Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime type checking and "downward" casting.

Usage example:

void foo(SoNode * node)
{
if (node->getTypeId() == SoFile::getClassTypeId()) {
SoFile * filenode = (SoFile *)node; // safe downward cast, knows the type
}
}
The SbList class is a template container class for lists.
Definition SbList.h:70
virtual SoType getTypeId(void) const =0
Returns the type identification of an object derived from a class inheriting SoBase....
The SoFile class is node container for another model file.
Definition SoFile.h:43
static SoType getClassTypeId(void)
Definition SoFile.cpp:100
The SoNode class is the base class for nodes used in scene graphs.
Definition SoNode.h:56

For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the predefined macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.

For more information on writing Coin extensions, see the class documentation of the top level superclasses for the various class groups.

Implements SoBase.

Member Data Documentation

◆ input

SoMField * SoConcatenate::input[10]

The multivalue input fields which we will concatenate into the output.

◆ output

SoEngineOutput * SoConcatenate::output

(SoMField) This is the field output containing the concatenated values of all the input fields.

The type of the field will of course match the type of the input field.
