MyEndString is string = "abcdef"
MyDifferenceBuffer is Buffer
MyDifferenceBuffer = diffCreate(MySourceString, MyEndString, diffText)
MyDecodeBuffer is Buffer
MyDecodeBuffer = diffApply(MySourceString, MyDifferenceBuffer)
SourceBuffer is Buffer
EndBuffer is Buffer
MyDifferenceBuffer is Buffer
MyDifferenceBuffer = diffCreate(SourceBuffer, EndBuffer, diffBinary)
MyDecodeBuffer is Buffer
MyDecodeBuffer = diffApply(SourceBuffer, MyDifferenceBuffer)
Syntax
<Result> = diffApply(<Buffer to process> , <Difference buffer>)
<Result>: Buffer variable Result once the difference buffer has been applied. This result can correspond to: - the new buffer searched.
- an empty buffer if an error occurred. In this case, the ErrorOccurred variable is set to True.
<Buffer to process>: Buffer variable Name of buffer to process. <Difference buffer>: Buffer variable Name of the difference buffer that must be applied to <Buffer to process>. This buffer was created by diffCreate. Remarks Error cases Applying the difference buffer may fail in the following cases: - The difference buffer does not use a recognized format.
- <Buffer to process> is not the buffer from which the difference buffer was created.
- The result does not correspond to the buffer that must be found (internal check).
