LibraryGroup (GWT 2.6.1)

java.lang.Object
- com.google.gwt.dev.cfg.LibraryGroup

```
public class LibraryGroup
extends Object
```
A convenience wrapper around a set of libraries.
Indexes library contents to enable single step retrieval of resources by name.
Analyzes the library dependency tree to provide link ordering and property and rebound type change analysis for partial generator execution.
Combines library resource lists for easy iteration over the complete set.

                                         boolean verifyLibraryReferences)
```
    Factory function that constructs and returns a library group from a list of libraries.
  - fromZipPaths
```
public static LibraryGroup fromZipPaths(List<String> zipLibraryPaths)
                                 throws com.google.gwt.dev.cfg.Libraries.IncompatibleLibraryVersionException

  - gatherNewConfigurationPropertyValuesForGenerator
```
public com.google.gwt.thirdparty.guava.common.collect.Multimap<String,String> gatherNewConfigurationPropertyValuesForGenerator(String generatorName)
```
    Walks the parts of the library dependency graph that have not run the given generator referenced by name and accumulates and returns a map from configuration property name to newly set values that were declared in those libraries.
  - gatherNewReboundTypeNamesForGenerator
```
public Set<String> gatherNewReboundTypeNamesForGenerator(String generatorName)
```
    Walks the parts of the library dependency graph that have not run the given generator referenced by name and accumulates and returns a set of newly rebound type names.
  - gatherOldReboundTypeNamesForGenerator
```
public Set<String> gatherOldReboundTypeNamesForGenerator(String generatorName)
```
    Walks the parts of the library dependency graph that have already run the given generator referenced by name and accumulates and returns the set of old rebound type names.
  - getBuildResourceByPath
```
public Resource getBuildResourceByPath(String buildResourcePath)
```
    Returns the resource referenced by name if present or null;
  - getBuildResourcePaths
```
public Set<String> getBuildResourcePaths()
```
    Returns the set of all build resource paths.
  - getClassFileStream
```
public InputStream getClassFileStream(String classFilePath)
```
    Opens and returns an input stream for the given class file path if present or null.
