Member Function Documentation

virtual Handle< VrmlData_Node > VrmlData_Node::Clone ( const Handle< VrmlData_Node > &  ) const

Create a copy of this node. If the parameter is null, a new copied node is created. Otherwise new node is not created, but rather the given one is modified.

This method nullifies the argument node if its member myScene differs from that one of the current instance.

Reimplemented in VrmlData_IndexedFaceSet, VrmlData_IndexedLineSet, VrmlData_Material, VrmlData_Group, VrmlData_Cylinder, VrmlData_Cone, VrmlData_Appearance, VrmlData_TextureCoordinate, VrmlData_Box, VrmlData_ShapeNode, VrmlData_WorldInfo, VrmlData_Color, VrmlData_Sphere, VrmlData_Coordinate, VrmlData_Normal, and VrmlData_ImageTexture.

static Standard_Integer VrmlData_Node::GlobalIndent ( )

Define the common Indent in spaces, for writing all nodes.

virtual Standard_Boolean VrmlData_Node::IsDefault ( ) const

Returns True if the node is default, then it would not be written.

Reimplemented in VrmlData_IndexedFaceSet, VrmlData_IndexedLineSet, VrmlData_Material, VrmlData_Appearance, VrmlData_ArrayVec3d, VrmlData_ShapeNode, VrmlData_WorldInfo, and VrmlData_UnknownNode.

const char* VrmlData_Node::Name ( ) const

Query the name

static Standard_Boolean VrmlData_Node::OK ( const VrmlData_ErrorStatus  theStat)
static Standard_Boolean VrmlData_Node::OK ( VrmlData_ErrorStatus outStat,
const VrmlData_ErrorStatus  theStat 
virtual VrmlData_ErrorStatus VrmlData_Node::Read ( VrmlData_InBuffer theBuffer)
pure virtual
static VrmlData_ErrorStatus VrmlData_Node::ReadBoolean ( VrmlData_InBuffer theBuffer,
Standard_Boolean theResult 

Read one boolean value (TRUE or FALSE).

static VrmlData_ErrorStatus VrmlData_Node::readBrace ( VrmlData_InBuffer theBuffer)

Read the closing brace. If successful, theBufrfer is incremented. If no brace is found, theBuffer stays in untouched and the method returns VrmlFormatError.

static VrmlData_ErrorStatus VrmlData_Node::ReadInteger ( VrmlData_InBuffer theBuffer,
long &  theResult 

Read one integer value.

static VrmlData_ErrorStatus VrmlData_Node::ReadMultiString ( VrmlData_InBuffer theBuffer,
NCollection_List< TCollection_AsciiString > &  theRes 

Read one quoted string, the quotes are removed.

VrmlData_ErrorStatus VrmlData_Node::ReadNode ( VrmlData_InBuffer theBuffer,
Handle< VrmlData_Node > &  theNode,
const Handle< Standard_Type > &  Type = NULL 

Read a complete node definition from VRML stream

theBufferBuffer receiving the input data.
theNode[out] Node restored from the buffer data
TypeNode type to be checked. If it is NULL(default) no type checking is done. Otherwise the created node is matched and an error is returned if no match detected.
static VrmlData_ErrorStatus VrmlData_Node::ReadString ( VrmlData_InBuffer theBuffer,
TCollection_AsciiString theRes 

Read one quoted string, the quotes are removed.

const VrmlData_Scene& VrmlData_Node::Scene ( ) const

Query the Scene that contains this Node

virtual VrmlData_ErrorStatus VrmlData_Node::Write ( const char *  thePrefix) const
VrmlData_ErrorStatus VrmlData_Node::WriteClosing ( ) const

Write the closing brace in the end of a node output.
