attachmentInfoExistsFor() [1/2]

ElementType::List attachmentInfoExistsFor ( ) const

overridevirtual

Returns

A list of element types for which attachment info exists

See also

generateAttachmentInfo, discardAttachmentInfo, getAttached, isAttached

Implements MeshModelInterface.

attachmentInfoExistsFor() [2/2]

bool attachmentInfoExistsFor ( const ElementType::Type &  elementType ) const

overridevirtual

Parameters

elementType

The type of element we want to check if attachment info exists for

See also

generateAttachmentInfo, discardAttachmentInfo, getAttached, isAttached

Implements MeshModelInterface.

clone()

LodMeshModelInterface * clone ( ) const

overridevirtual

Derived classes should return their derived type.

Implements MeshModelInterface.

discardAttachmentInfo()

void discardAttachmentInfo ( const ElementType::Type &  elementType )

overridevirtual

Parameters

elementType

The type of element we want discard attachment info for

See also

generateAttachmentInfo, attachmentInfoExistsFor, attachmentInfoExistsFor, getAttached, isAttached

Implements MeshModelInterface.

doesLodDataExist()

bool doesLodDataExist ( ) const

inline

emptyTrash()

void emptyTrash ( )

overridevirtual

Depending on the implementation, removing nodes or elements may just mark their index as invalid rather than completely removing it from internal lists/storage. It should also be noted that removing a node does not guarantee any bookkeeping to update any attached elements, calling code is responsible for this if needed. Specific implementations of MeshModelInterface can use emptyTrash to completely remove any stored nodes and elements (e.g. in a single more efficient way after multiple remove operations) and can optionally use this to remove elements now referencing invalid nodes. This behaviour is implementation specific and calling code should check specific implementation class documentation.

Implements MeshModelInterface.

fastAssignFrom()

bool fastAssignFrom ( const MeshModelInterface &  other )

overrideprotectedvirtual

Perform assignment from another MeshModelInterface. This method is called by operator=() allowing the derived class to check other.getFactory() to see if the other object is the same type as themselves or some other known MeshModelInterface implementation that they can cast for faster assignment (via the derived class assignment operator for example). If the derived class can not offer a fast assignment then it must return false signaling that an assignment should be performed using just the base class interface.

Returns

true if a fast assignment has been performed or false if it couldn't.

operator=()

Implements MeshModelInterface.

generateAttachmentInfo()

bool generateAttachmentInfo ( const ElementType::Type &  elementType )

overridevirtual

Precondition

If the model has been modified since the last call to generateAttachmentInfo then clients should first call discardAttachmentInfo() before this call to ensure the correct attachment info exists.

Implements MeshModelInterface.

getAttachedElements()

ElementHandleList getAttachedElements ( const ElementType::Type &  elementType, const NodeHandle &  node  ) const

overridevirtual

Precondition

generateAttachmentInfo must have already been called successfully for elementType.

Parameters

elementType	The type of attached element
node	The node we're querying the attachments of

See also

generateAttachmentInfo, discardAttachmentInfo, attachmentInfoExistsFor, isAttached

Implements MeshModelInterface.

getElements() [1/2]

const MeshElementsInterface & getElements ( const ElementType::Type &  type ) const

overridevirtual

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Implements MeshModelInterface.

getElements() [2/2]

MeshElementsInterface & getElements ( const ElementType::Type &  type )

overridevirtual

Derived class should return MeshElementsInterface::getNullMeshElementsInterface() if an unsupported type is requested. This should be consistent with calls to isElementTypeSupported().

Implements MeshModelInterface.

getElementTypesPresentInModel()

ElementType::List getElementTypesPresentInModel ( ) const

overridevirtual

Returns

A list of ElementType::Types that this model currently contains.

Implements MeshModelInterface.

getElementTypesWithStatesDefined()

ElementType::List getElementTypesWithStatesDefined ( ) const

overridevirtual

Returns

A list of ElementType::Types that currently have states defined in this model.

Implements MeshModelInterface.

getNodes() [1/2]

const MeshNodesInterface & getNodes ( ) const

overridevirtual

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Implements MeshModelInterface.

getNodes() [2/2]

MeshNodesInterface & getNodes ( )

overridevirtual

Returns

A MeshNodesInterface

Implements MeshModelInterface.
