| Constructor

## Member Function Documentation

Standard_EXPORT Standard_Boolean VrmlData_ArrayVec3d::AllocateValues | ( | const Standard_Size | theLength | ) |

Create a data array and assign the field myArray.

Returns:
  True if allocation was successful.

virtual Standard_EXPORT Standard_Boolean VrmlData_ArrayVec3d::IsDefault | ( |  | ) | const`[virtual]`

| Returns True if the node is default, so that it should not be written. Reimplemented from VrmlData_Node.

size_t VrmlData_ArrayVec3d::Length | ( |  | ) | const`[inline]`

| Query the number of vectors

Standard_EXPORT VrmlData_ErrorStatus VrmlData_ArrayVec3d::ReadArray | ( | VrmlData_InBuffer & | theBuffer,
|  | const char * | theName,
|  | const Standard_Boolean | isScale
| ) |

| Read the Node from input stream.

void VrmlData_ArrayVec3d::SetValues | ( | const size_t | nValues,
|  | const gp_XYZ * | arrValues
| ) | `[inline]`

| Set the array data

Standard_EXPORT const gp_XYZ& VrmlData_ArrayVec3d::Value | ( | const Standard_Integer | i | ) | const`[protected]`

Query one vector

Parameters:

  | i | index in the array of vectors [0 .. N-1]

Returns:
  the vector for the index. If index irrelevant, returns (0., 0., 0.)

const gp_XYZ* VrmlData_ArrayVec3d::Values | ( |  | ) | const`[inline]`

| Query the array

Standard_EXPORT VrmlData_ErrorStatus VrmlData_ArrayVec3d::WriteArray | ( | const char * | theName,
|  | const Standard_Boolean | isScale
| ) | const

| Write the Node to the output stream currently opened in Scene.
