Constructor Detail

UnifiedAst

public UnifiedAst(JJSOptions options,
                  UnifiedAst.AST initialAst,
                  boolean singlePermutation,
                  Set<String> rebindRequests)

Method Detail

compilePermutation

public PermutationResult compilePermutation(TreeLogger logger,
                                            CompilerContext compilerContext,
                                            Permutation permutation)
                                     throws UnableToCompleteException

Compiles a particular permutation.

Parameters:

logger - the logger to use

compilerContext - shared read only compiler state

permutation - the permutation to compile

Returns:

the permutation result

Throws:

UnableToCompleteException - if an error other than OutOfMemoryError occurs

getFreshAst

public UnifiedAst.AST getFreshAst()

Return the current AST so that clients can explicitly walk the Java or JavaScript parse trees.

Returns:

the current AST object holding the Java and JavaScript trees.

getModuleMetrics

public ModuleMetricsArtifact getModuleMetrics()

Returns metrics about the module load portion of the build.

getOptions

public JJSOptions getOptions()

Returns the active set of JJS options associated with this compile.

getPrecompilationMetrics

public PrecompilationMetricsArtifact getPrecompilationMetrics()

Returns metrics about the precompilation portion of the build.

getRebindRequests

public SortedSet<String> getRebindRequests()

Returns the set of live rebind requests in the AST.

prepare

public void prepare()

Internally prepares a new AST for compilation if one is not already prepared.

setModuleMetrics

public void setModuleMetrics(ModuleMetricsArtifact metrics)

Save some module load metrics in the AST.

setPrecompilationMetrics

public void setPrecompilationMetrics(PrecompilationMetricsArtifact metrics)

Save some precompilation metrics in the AST.
