Description copied from class: AbstractHashCodeHLC

Compute a Hash-Code

Specified by:

computeCacheKey in class AbstractHashCodeHLC<java.lang.Long>

Parameters:

codeTypeParam - The code type identifier (e.g., 'java', 'html', 'css') used to distinguish syntax rules.

includeLineNumbers - A flag indicating whether line numbers are to be included in the highlighted HTML output.

styleNum - A numeric style identifier used to determine which syntax color scheme should be applied.

sourceCodeAsString - The unhighlighted source code text which is used for generating a "Hash Key" into the cache.

Returns:

A key which may be used for saving a file to disk.

Exact Method Body:

 final long FNV_PRIME = 0x100000001b3L;
 long hash = 0xcbf29ce484222325L;
    
 // Mix in codeTypeParam
 for (int i = 0; i < codeTypeParam.length(); i++) {
     hash ^= codeTypeParam.charAt(i);
     hash *= FNV_PRIME;
 }
    
 // Mix in includeLineNumbers
 hash ^= (includeLineNumbers ? 1 : 0);
 hash *= FNV_PRIME;
    
 // Mix in styleNum
 hash ^= styleNum;
 hash *= FNV_PRIME;
    
 // Mix in sourceCodeAsString
 for (int i = 0; i < sourceCodeAsString.length(); i++) {
     hash ^= sourceCodeAsString.charAt(i);
     hash *= FNV_PRIME;
 }
    
 return hash;
