Method Detail

bytesToChar

public static char[] bytesToChar(byte[] bytes,
                                 java.lang.String encoding)
                          throws java.io.IOException

Returns the given bytes as a char array using a given encoding (null means platform default).

Throws:

java.io.IOException

getFileByteContent

public static byte[] getFileByteContent(java.io.File file)
                                 throws java.io.IOException

Returns the contents of the given file as a byte array.

Throws:

java.io.IOException - if a problem occured reading the file.

getFileCharContent

public static char[] getFileCharContent(java.io.File file,
                                        java.lang.String encoding)
                                 throws java.io.IOException

Returns the contents of the given file as a char array. When encoding is null, then the platform default one is used

Throws:

java.io.IOException - if a problem occured reading the file.

getInputStreamAsByteArray

public static byte[] getInputStreamAsByteArray(java.io.InputStream stream,
                                               int length)
                                        throws java.io.IOException

Returns the given input stream's contents as a byte array. If a length is specified (ie. if length != -1), only length bytes are returned. Otherwise all bytes in the stream are returned. Note this doesn't close the stream.

Throws:

java.io.IOException - if a problem occured reading the stream.

getInputStreamAsCharArray

public static char[] getInputStreamAsCharArray(java.io.InputStream stream,
                                               int length,
                                               java.lang.String encoding)
                                        throws java.io.IOException

Returns the given input stream's contents as a character array. If a length is specified (ie. if length != -1), this represents the number of bytes in the stream. Note this doesn't close the stream.

Throws:

java.io.IOException - if a problem occured reading the stream.

getZipEntryByteContent

public static byte[] getZipEntryByteContent(java.util.zip.ZipEntry ze,
                                            java.util.zip.ZipFile zip)
                                     throws java.io.IOException

Returns the contents of the given zip entry as a byte array.

Throws:

java.io.IOException - if a problem occured reading the zip entry.

isArchiveFileName

public static final boolean isArchiveFileName(java.lang.String name)

Returns true iff str.toLowerCase().endsWith(".jar") || str.toLowerCase().endsWith(".zip") implementation is not creating extra strings.

isClassFileName

public static final boolean isClassFileName(char[] name)

Returns true iff str.toLowerCase().endsWith(".class") implementation is not creating extra strings.

isClassFileName

public static final boolean isClassFileName(java.lang.String name)

Returns true iff str.toLowerCase().endsWith(".class") implementation is not creating extra strings.

isExcluded

public static final boolean isExcluded(char[] path,
                                       char[][] inclusionPatterns,
                                       char[][] exclusionPatterns,
                                       boolean isFolderPath)

isJavaFileName

Converts an array of Objects into String.

toString

public static java.lang.String toString(java.lang.Object[] objects,
