Method Detail

decode

public String decode(String encodedStr)

Decodes an encoded string from the JS Compiler ReplaceStrings pass.

An original string with args might look like this:

  Error('Some ' + arg1 + ' error ' + arg2 + ' message.');

Which gets replaced with:

  Error('key' + '`' + arg1 + '`' + arg2);

Where ` is the argument place holder. The replacement mapping would be:

  key → 'Some ` error ` message.'

Where key is some arbitrary replacement string. An encoded string, with args, from the client will look like:

  'key`arg1`arg2'

Parameters:

encodedStr - An encoded string.

Returns:

The decoded string, or the encoded string if it fails to decode.
