Feature contributions
| Feature | Value | Contribution (log-odds) |
|---|---|---|
| Halstead volumeHow much symbolic information the code contains. It combines the total number of operators and values with the number of distinct ones. | 965.73 | −31.869 |
| Source linesThe number of non-empty source lines. | 45 | +18 |
| Byte entropyHow varied the bytes in the source text are. Repeated bytes give a lower value; a more even mixture gives a higher value. | 4.991 | −7.487 |
Intercept 8.87 + feature contributions = -12.486 (log-odds).

Run 1
The code is well-structured as a concise interface definition. Constants are logically grouped and consistently formatted, though the list is long. The interface avoids unnecessary nesting and has a clear purpose: defining a custom private key method for SSL operations. Method signatures are concise with clear parameter names and return types. Javadoc comments effectively document intent and behavior. Reading flow is natural, with constants first, then methods, and clear documentation separating them. Minor deductions result from repetitive constant declarations and slight verbosity in Javadoc, but overall readability is high.
Run 2
The code is highly readable. It has a clear structure: package declaration, imports, interface documentation, constants, and method signatures are logically organized. There is no nesting, and intent is explicit—both the interface's purpose and each method's role are documented with Javadoc. The constant declarations, though numerous, follow a consistent pattern and simply forward values from an underlying library, which is concise given the context. Each constant occupies one line, and method signatures are clean with one parameter per line in Javadoc. The reading flow is natural: constants first, then methods with clear documentation. Minor deductions: the large number of constants could benefit from grouping comments, and the interface documentation could explain why the constants are defined rather than inherited. Overall, this is exemplary for API-style Java code.
Run 3
The code is highly readable. It has a clear, logical structure: package, imports, Javadoc, interface declaration, constants, and method signatures. Nesting is effectively flat since it is an interface with only constants and abstract methods. Intent is clearly communicated through the interface name and detailed Javadoc comments that explain parameters, return values, and exceptions. Code length is appropriate; constants are concise and self-explanatory. Action granularity and reading flow are natural, following standard Java conventions. Minor deductions for a long line in the Javadoc and repetitive constant declarations, but these do not significantly impact overall readability.
Run 1
Code Structure: Logically organized into imports, interface documentation, algorithm constants, and two documented methods. Nesting: Flat interface declarations with no nested control flow. Clarity of intent: Descriptive constant and method names plus parameter and return documentation clearly communicate the API's purpose; references to a 'given key' are slightly ambiguous because no key parameter is exposed. Code length: Concise for the API represented, although the repetitive constant block adds visual bulk. Action granularity: Each constant and method declaration occupies its own line. Reading flow: Natural progression from supported algorithms to operations, with whitespace separating methods; blank lines after the package declaration and between algorithm families would improve scanning.
Run 2
Code Structure: Logically organized into imports, interface constants, and documented method declarations. Nesting: Flat, with no nested control flow. Clarity of intent: Descriptive algorithm constants and method names clearly communicate the interface's purpose; Javadoc explains parameters and return values, though the opening description is awkward and 'given key' is implicit rather than specified. Code length: Concise for its API surface; repetitive constant aliases are justified. Action granularity: Each constant or method declaration occupies its own line. Reading flow: Naturally progresses from supported algorithms to signing and decryption operations. Minor improvements include separating imports from the package declaration and visually grouping constants by algorithm family.
Run 3
Code Structure: Logically organized into imports, algorithm constants, and two documented interface methods. Nesting: Flat, with no nested control flow. Clarity of intent: Descriptive names and Javadoc clearly convey signing and decryption responsibilities, although the opening RSA wording is ambiguous and 'atm' is informal. Code length: Concise for its purpose; repetitive constant aliases are justified but visually dominate the interface. Action granularity: Each constant and method declaration occupies its own line. Reading flow: Natural top-to-bottom progression, with consistent formatting and clear separation between methods. Blank lines between import groups and related algorithm families would improve scanning.
