Method Detail

compress

public static java.lang.String compress(java.lang.String encodedSource,
                                        int flags,
                                        UintMap properties,
                                        ScriptOrFnNode parseTree)

Compress the script

Parameters:

encodedSource - encoded source string

flags - Flags specifying format of decompilation output

properties - Decompilation properties

parseTree - Mapping for each function node and corresponding parameters & variables names

Returns:

compressed script

decompile

public static java.lang.String decompile(java.lang.String source,
                                         int flags,
                                         UintMap properties)

Decompile the source information associated with this js function/script back into a string. For the most part, this just means translating tokens back to their string representations; there's a little bit of lookahead logic to decide the proper spacing/indentation. Most of the work in mapping the original source to the prettyprinted decompiled version is done by the parser.

Parameters:

source - encoded source tree presentation

flags - flags to select output format

properties - indentation properties
