Method Details
-
getCompressedFilename
Deprecated.Maps the given file name to the name that the file should have after compression with gzip. Common file types with custom suffixes for compressed versions are automatically detected and correctly mapped. For example the name "package.tar" is mapped to "package.tgz". If no custom mapping is applicable, then the default ".gz" suffix is appended to the file name.- Parameters:
fileName- name of a file- Returns:
- name of the corresponding compressed file
-
getCompressedFileName
Maps the given file name to the name that the file should have after compression with gzip. Common file types with custom suffixes for compressed versions are automatically detected and correctly mapped. For example the name "package.tar" is mapped to "package.tgz". If no custom mapping is applicable, then the default ".gz" suffix is appended to the file name.- Parameters:
fileName- name of a file- Returns:
- name of the corresponding compressed file
- Since:
- 1.25.0
-
getUncompressedFilename
Deprecated.Maps the given name of a gzip-compressed file to the name that the file should have after uncompression. Commonly used file type specific suffixes like ".tgz" or ".svgz" are automatically detected and correctly mapped. For example the name "package.tgz" is mapped to "package.tar". And any file names with the generic ".gz" suffix (or any other generic gzip suffix) is mapped to a name without that suffix. If no gzip suffix is detected, then the file name is returned unmapped.- Parameters:
fileName- name of a file- Returns:
- name of the corresponding uncompressed file
-
getUncompressedFileName
Maps the given name of a gzip-compressed file to the name that the file should have after uncompression. Commonly used file type specific suffixes like ".tgz" or ".svgz" are automatically detected and correctly mapped. For example the name "package.tgz" is mapped to "package.tar". And any file names with the generic ".gz" suffix (or any other generic gzip suffix) is mapped to a name without that suffix. If no gzip suffix is detected, then the file name is returned unmapped.- Parameters:
fileName- name of a file- Returns:
- name of the corresponding uncompressed file
- Since:
- 1.25.0
-
isCompressedFilename
Deprecated.Detects common gzip suffixes in the given file name.- Parameters:
fileName- name of a file- Returns:
trueif the file name has a common gzip suffix,falseotherwise
-
isCompressedFileName
Detects common gzip suffixes in the given file name.- Parameters:
fileName- name of a file- Returns:
trueif the file name has a common gzip suffix,falseotherwise- Since:
- 1.25.0
