Directory Byte Stream Searching Module for Text Files
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for generating directories in TXT text files are time-consuming and inefficient, particularly in mobile computing environments, due to the need for character matching and conversion of byte streams, which limits quick content location and section navigation.
Innovation Solution
A method and device that search for directory byte streams in text files without converting bytes to characters, using a directory byte stream searching module to identify predetermined directory key bytes and generate directories based on these streams, reducing computational and memory requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If character matching method is used to generate directory, then directory can be generated, but time consumption increases and processing speed decreases
Solution Approach 1:
The patent extracts only the essential directory signature bytes from the text file without converting the entire byte stream to characters. By searching for specific directory signature patterns directly in the byte stream, the method eliminates the time-consuming full character conversion process while still accurately identifying directory positions.
Solution Approach 2:
The patent performs preliminary identification of directory positions by searching for signature bytes before any character conversion occurs. This preliminary action allows the system to locate directories efficiently in the raw byte stream, avoiding the need to convert all bytes to characters first.
2Measurement precision
If full byte stream conversion to character string is performed, then character matching can be done, but computational capacity and memory capacity requirements increase
Solution Approach 1:
The patent extracts only the necessary directory signature bytes from the text file without converting the entire byte stream to characters. By searching for specific directory signature patterns directly in the byte stream, the method eliminates the need to load and process the full converted character string in memory.
Solution Approach 2:
Instead of converting the entire byte stream to characters, the patent performs partial action by only converting and processing the specific byte segments containing directory signatures. This selective approach reduces memory usage while still achieving accurate directory identification.
3Measurement precision
If character matching method is used, then directory can be identified, but processing speed and efficiency decrease
Solution Approach 1:
The patent replaces the mechanical character-by-character matching process with a more efficient byte-pattern search mechanism. By using signature byte matching instead of full character string comparison, the system achieves faster processing speeds while maintaining accurate directory identification.
Solution Approach 2:
The patent performs preliminary identification of directory positions by searching for signature bytes before any character conversion occurs. This preliminary action allows the system to locate directories efficiently in the raw byte stream, significantly improving processing speed compared to post-conversion character matching.

AI summary
A method and a device for directory generation are provided in the present disclosure. The method comprises searching a directory byte stream in a text file. The directory byte stream includes a predetermined directory key byte corresponding to a predetermined directory character. The method also comprises generating a directory of the text file based on the directory byte stream.
