Method Detail

readFileFromFileSystemBase64Encoded

public static byte[] readFileFromFileSystemBase64Encoded(java.lang.String filePathToRead)

Retrieves encoded Base64 file content. If file would be encoded it'll be returned without encoded.

Parameters:

filePathToRead - absolute file path.

Returns:

Base64 file content.

readFileBase64Encoded

public static java.lang.String readFileBase64Encoded(java.lang.String path,
                                                     boolean isRelativePath)

Reads a file from system by given path (absolute or relative to classpath) and encodes to Base64 format.

Parameters:

path - file path.

isRelativePath - true if path is relative to classpath and false if path is absolute.

Returns:

content file encoded in base64. Returns a null value if an error happens

getFileBase64Encoded

public static java.lang.String getFileBase64Encoded(byte[] content)

Method that obtains a String encoded on Base64 from the content of a file.

Parameters:

content - Parameter that represents the content of a file.

Returns:

the encoded Base64 String.

getArrayByteFileBase64Encoded

public static byte[] getArrayByteFileBase64Encoded(java.lang.String path,
                                                   boolean isRelativePath)

Reads a file from system by given path (absolute or relative to classpath) and encodes to Base64 format.

Parameters:

path - file path.

isRelativePath - true if path is relative to classpath and false if path is absolute.

Returns:

content file encoded in base64. Returns a null value if an error happens

readFile

public static byte[] readFile(java.lang.String path,
                              boolean isRelativePath)

Reads a file from system by given path (absolute or relative to classpath).

Parameters:

path - file path.

isRelativePath - true if path is relative to classpath and false if path is absolute.

Returns:

content file. Returns a null value if an error happens

writeFile

public static void writeFile(byte[] data,
                             java.lang.String filename)
                      throws java.io.IOException
