## Methods

| Method | Description |
| --- | --- |
| [canReuseTransform()](#canReuseTransform--) | Gets a value indicating whether the current transform can be reused. |
| [canTransformMultipleBlocks()](#canTransformMultipleBlocks--) | Gets a value indicating whether multiple blocks can be transformed. |
| [dispose()](#dispose--) | Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources. |
| [getInputBlockSize()](#getInputBlockSize--) | Gets the input block size. |
| [getOutputBlockSize()](#getOutputBlockSize--) | Gets the output block size. |
| [transformBlock(byte[] inputBuffer, int inputOffset, int inputCount, byte[] outputBuffer, int outputOffset)](#transformBlock-byte---int-int-byte---int-) | Transforms the specified region of the input byte array and copies the resulting transform to the specified region of the output byte array. |
| [transformFinalBlock(byte[] inputBuffer, int inputOffset, int inputCount)](#transformFinalBlock-byte---int-int-) | Transforms the specified region of the specified byte array. |
### canReuseTransform() {#canReuseTransform--}
```
public abstract boolean canReuseTransform()
```


Gets a value indicating whether the current transform can be reused.
