|
| IsString |
Returns true if the node is a text string
|
| ItemInt32 |
returns element of a sequence node
|
| ItemString |
returns element of a mapping node
|
| Name |
Returns the node name or an empty string if the node is nameless
|
| Size |

|
Methods
| Name | Description | |
|---|---|---|
 | AllocGCHandle |
Pins the object to be allocated by cvSetData.
(Inherited from DisposableObject.) |
| AllocMemory |
Allocates the specified size of memory.
(Inherited from DisposableObject.) |
| Dispose |
Releases the resources
(Inherited from DisposableObject.) |
| Dispose(Boolean) | Releases the unmanaged resources used by the FileNode and optionally releases the managed resources (Overrides DisposableCvObjectDispose(Boolean).) |
| Equals | (Inherited from Object.) |
| Finalize |
Destructor
(Inherited from DisposableObject.) |
| GetHashCode | (Inherited from Object.) |
| GetType | (Inherited from Object.) |
| MemberwiseClone | (Inherited from Object.) |
| NotifyMemoryPressure |
Notifies the allocated size of memory.
(Inherited from DisposableObject.) |
| ReadDouble | |
| ReadFloat | |
| ReadInt | |
| ReadKeyPoints | |
| ReadMat | |
| ReadObj |
Reads the registered object and returns pointer to it
|
| ReadRaw |
Reads node elements to the buffer with the specified format
|
| ReadSparseMat | |
| ReadString | |
| ThrowIfDisposed |
If this object is disposed, then ObjectDisposedException is thrown.
(Inherited from DisposableObject.) |
| ToLegacy |
Returns pointer to the underlying C FileStorage structure
|
| ToString | (Inherited from Object.) |
Operators
| Name | Description | |
