Method Detail

compressPackagesInMessage

static java.lang.String compressPackagesInMessage(java.lang.String input)

Compresses an error message by stripping the packages out of class names and adding them to a legend at the bottom of the error.

replaceFullNames

private static com.google.common.collect.ImmutableSet<java.lang.String> replaceFullNames(java.lang.String input,
                                                                                         java.util.Map<java.lang.String,java.lang.String> replacementMap,
                                                                                         java.lang.StringBuilder output)

Replaces full class names in input and append the replaced content to output and then returns a set of short names that were used as replacement.

String literals that are quoted in the input will be added to the output unchanged. So any full class name that only appear in the string literal will not be included in the returned short names set.

buildClassNameLegend

private static java.lang.String buildClassNameLegend(java.util.Map<java.lang.String,java.lang.String> replacementMap)

shortenNames

private static java.util.Map<java.lang.String,java.lang.String> shortenNames(java.util.Collection<java.lang.String> names)

Returns a map from short name to full name after resolving conflicts. This resolves conflicts by adding on segments of the package name until they are unique. For example, com.foo.Baz and com.bar.Baz will conflict on Baz and then resolve with foo.Baz and bar.Baz as replacements.
