compare back to summary

compare	back to summary
pack-priv byte compare(String str, byte[] b, int off, int len, boolean matchDirectory) This method is used by ZipFile.Source.getEntryPos when comparing the name being looked up to candidate names encoded in the CEN byte array. Since ZipCode.getEntry supports looking up a "dir/" entry by the name "dir", this method can optionally distinguish an exact match from a partial "directory match" (where names only differ by the encoded name having an additional trailing '/') The return values of this method are as follows: If the lookup name is exactly equal to the encoded string, return `EXACT_MATCH`. If the parameter `matchDirectory` is `true` and the two strings differ only by the encoded string having an extra trailing '/' character, then return `DIRECTORY_MATCH`. Otherwise, return `NO_MATCH` While a general implementation will need to decode bytes into a String for comparison, this can be avoided if the String coder and this ZipCoder are known to encode strings to the same bytes. Parameters str:String The lookup string to compare with the encoded string. b:byte[] The byte array holding the encoded string off:int The offset into the array where the encoded string starts len:int The length of the encoded string in bytes matchDirectory:boolean If `true` and the strings do not match exactly, a directory match will also be tested

pack-priv byte compare(String str, byte[] b, int off, int len, boolean matchDirectory)

This method is used by ZipFile.Source.getEntryPos when comparing the name being looked up to candidate names encoded in the CEN byte array. Since ZipCode.getEntry supports looking up a "dir/" entry by the name "dir", this method can optionally distinguish an exact match from a partial "directory match" (where names only differ by the encoded name having an additional trailing '/') The return values of this method are as follows: If the lookup name is exactly equal to the encoded string, return EXACT_MATCH. If the parameter matchDirectory is true and the two strings differ only by the encoded string having an extra trailing '/' character, then return DIRECTORY_MATCH. Otherwise, return NO_MATCH While a general implementation will need to decode bytes into a String for comparison, this can be avoided if the String coder and this ZipCoder are known to encode strings to the same bytes.

Parameters

str:String: The lookup string to compare with the encoded string.
b:byte[]: The byte array holding the encoded string
off:int: The offset into the array where the encoded string starts
len:int: The length of the encoded string in bytes
matchDirectory:boolean: If true and the strings do not match exactly, a directory match will also be tested
