| Constructor Detail |
RPMFile
public RPMFile()
- Creates a new empty RPMFile object.
RPMFile
public RPMFile(java.io.File fh) throws java.io.IOException
- Creates a new RPMFile object out of a file.
RPMFile
public RPMFile(java.io.InputStream rpmInputStream) throws java.io.IOException
- Creates a new RPMFile object out of a input stream.
| Method Detail |
getHeader
public RPMHeader getHeader()
- Get the header section of this rpm file.
getKnownTagNames
public static java.lang.String[] getKnownTagNames()
- Get all known tags of this rpm file. This is equivalent to
the --querytags option in rpm.
getLead
public RPMLead getLead()
- Get the lead section of this rpm file
setLocale
public void setLocale(int pos)
- Set the locale as int for all I18N strings that are
returned by getTag(). The position has to correspond
with the same position in the array returned by
getLocales().
setLocale
public void setLocale(java.lang.String locale)
- Set the locale as string for all I18N strings that are
returned by getTag(). The string must match with a string
returned by getLocales().
getLocales
public java.lang.String[] getLocales()
- Return all known locales that are supported by this RPM file.
The array is read out of the RPM file with the tag
"HEADERI18NTABLE". The RPM has one entry for all I18N strings
defined by this tag.
setPayloadArchive
public void setPayloadArchive(PayloadArchive payloadArchive)
getPayloadArchive
public PayloadArchive getPayloadArchive() throws java.io.IOException
- Get the archive as a CPIO Archive.
