## Detailed Description

I/O operations on scene files.

Methods for opening, saving, importing, exporting and referencing files.

The MFileIO class provides a set of global functions that can be used to load and store scene elements into maya files. Methods are also provided to import elements from other files into the current scene, and export elements of the current scene into files. As well, references to other files can be created and removed.

This class implements only the most common operations from the full set possible with the MEL command "file." See the documentation of this command for a complete listing of all the possiblities. If more control is required than provided by this class, a MEL command can be constructed according to the instructions for the "file" command, and issued via the executeCommand method of the MGlobal class.

|  | MPlugArray & | srcPlugs,
|  | MPlugArray & | destPlugs,
|  | bool | append = `false`,
|  | bool | removeDuplicates = `true`
| ) |  | `[static]`

Search for all occurrences

Returns arrays of source and destination plugs corresponding to the broken connections from referenced files, where those connections involved the specified node.

To put it another way, if a referenced file contained a connection to the specified node when it was loaded, and that connection was later broken in the main scene, then the source and destination plugs for that connection will be returned.

Parameters:

  [in] | node | the node whose broken connections should be returned.
  [out] | srcPlugs | an MPlugArray which will receive the source plugs of each broken connection.
  [out] | destPlugs | an MPlugArray which will receive the destination plugs of each broken connection.
  [in] | append | if true, then srcPlugs and destPlugs will not be initially cleared, meaning that the plugs from any broken connections found will be appended after whatever is already in those arrays. This can be useful for building up an array of connections for several nodes.
  [in] | removeDuplicates | if the append parameter is true, then it is possible that some of the broken connections found for node will already exist in plug arrays. For example, if node A and node B have a broken reference connection between them, then they will both return that connection when passed to this method. Setting removeDuplicates true will cause these duplicate connections to only appear in the plug arrays once.

Returns:
  - MS::kSuccess operation successful
  - MS::kFailure operation failed

MStatus reference | ( | const MString & | fileName,
|  | bool | deferReference = `false`,
|  | bool | lockReference = `false`,
|  | const MString & | nameSpace = `""`
| ) |  | `[static]`

Search for all occurrences

Add the given filename as a reference from the current file.

When a new file is opened, the contents of any files it references are read into the scene, however maya remembers that the elements came from the referenced file, and does not write them during a save operation. Instead the reference is written so the contents of the referenced file (which might have changed) will be read again when the scene is reloaded.

Parameters:

  [in] | fileName | name of the file to add as a reference.
  [in] | deferReference | boolean to indicate whether loading has to be deferred.
  [in] | lockReference | If true, all nodes and attributes from the referenced file will be locked.
  [in] | nameSpace | name space to add the contents of the referenced file to. If no namespace is provided, name-clashes will be resolved by prefixing with the filename.

Returns:
  - MS::kSuccess operation successful
  - MS::kFailure operation failed

MStatus removeReference | ( | const MString & | fileName,
|  | NamespaceMergeMethod | namespaceMergeMethod = `kRemoveNamespaceIfEmpty`
| ) |  | `[static]`

Search for all occurrences

Remove the named file as a reference from the current file.

Parameters:

  [in] | fileName | name of the file to remove as a reference
  [in] | namespaceMergeMethod | what to do with objects remaining in the namespace after the file is removed: merge with parent namespace, merge with root namespace, delete all objects, or keep objects in the namespace (default). Merge with parent/root and delete all objects cannot be used if the reference resides in the root namespace.

Returns:
  - MS::kSuccess operation successful
  - MS::kFailure operation failed

bool isReadingFile | ( |  | ) | `[static]`

Search for all occurrences

Determine if Maya is currently in the middle of a file read operation.

File import operations and file reference operations are both also file read operations.

Returns:
  - true if maya is currently in the process of reading a file
  - false if maya is not currently reading a file

Examples:
  cgfxShaderNode.cpp.

bool isWritingFile | ( |  | ) | `[static]`

Returns:
  - true if maya is currently in the process of writing a file
  - false if maya is not currently writing a file

bool isOpeningFile | ( |  | ) | `[static]`

Search for all occurrences

Determine if Maya is currently performing a file open operation.

This condition differs from isReadingFile() which is only true when were are actually reading the contents of the file from disk. In contrast, isOpeningFile() will be true during the pre-read operations such as the new operation to delete the current scene contents as well as post read-operations.

The isOpeningFile() method can be used in conjunction with isNewingFile() to determine if a "new" operation is currently being performed on behalf of an "open" operation.

Maya performs two types of "new" operations: 1) explicit "new" on account of a File>New or "file -new", and 2) implicit "new" due to file open. The isOpeningFile() method can be used in conjunction with isNewingFile() to determine if a "new" operation is currently being performed on behalf of an "open" operation. The following table lists how the isNewingFile() and isOpeningFile() methods can be used to determine the current state:

| isNewingFile() returns false | isNewingFile() returns true
isOpeningFile() returns false | Maya is neither in new nor open | Maya is perfroming an explicit new (a File>New or file -new)
isOpeningFile() returns true | Maya is opening a file, and is not currently performing a new | Maya is opening a file and is performing a new on behalf of the open

Based on the above table, it is easy to see how the four distinct states can easily be detected.

Returns:
  - true if maya is currently in the process of opening a file
  - false if maya is not currently opening a file

Examples:
  cgfxShaderNode.cpp.

bool isNewingFile | ( |  | ) | `[static]`

Search for all occurrences

Determine if Maya is currently performing a "new" operation.

Maya performs two types of "new" operations: 1) explicit "new" on account of a File>New or "file -new", and 2) implicit "new" due to file open. The isOpeningFile() method can be used in conjunction with isNewingFile() to determine if a "new" operation is currently being performed on behalf of an "open" operation. The following table lists how the isNewingFile() and isOpeningFile() methods can be used to determine the current state:

| isNewingFile() returns false | isNewingFile() returns true
isOpeningFile() returns false | Maya is neither in new nor open | Maya is perfroming an explicit new (a File>New or file -new)
isOpeningFile() returns true | Maya is opening a file, and is not currently performing a new | Maya is opening a file and is performing a new on behalf of the open

Based on the above table, it is easy to see how the four distinct states can easily be detected.

Returns:
  - true if maya is currently in the process of a new operation.
  - false if maya is not currently in new.
