Package proguard.io

Class ClassMapDataEntryWriter

java.lang.Object

proguard.io.ClassMapDataEntryWriter

All Implemented Interfaces:

AutoCloseable, MemberVisitor, DataEntryWriter

public class ClassMapDataEntryWriter
extends Object
implements DataEntryWriter, MemberVisitor

This DataEntryWriter writes a class mapping to the given data entry, used for debugging of the configuration.

Syntax of the mapping file (one line per class):

originalClassName,newClassName,hasObfuscatedMethods,hasObfuscatedFields

hasObfuscatedMethods and hasObfuscatedFields can either take the value 0 (false) or 1 (true).

Method Details

close

public void close()
           throws IOException

Description copied from interface: DataEntryWriter

Finishes writing all data entries.

Implementations typically create graphs of writers that can split and merge again, possibly even with cycles.

For splits and merges, implementations need to be idempotent; once closed, subsequent attempts to close a writer have no effect. If needed, the wrapper NonClosingDataEntryWriter can avoid closing a branch prematurely.

For cycles, implementations must perform any custom behavior, then delegate DataEntryWriter.close() invocations, and only finally clean up. It is possible that delegates call DataEntryWriter.createOutputStream(DataEntry) while DataEntryWriter.close() is in progress.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface DataEntryWriter

Throws:

IOException

createDirectory

public boolean createDirectory(DataEntry dataEntry)
                        throws IOException

Description copied from interface: DataEntryWriter

Creates a directory.

Specified by:

createDirectory in interface DataEntryWriter

Parameters:

dataEntry - the data entry for which the directory is to be created.

Returns:

whether the directory has been created.

Throws:

IOException

sameOutputStream

public boolean sameOutputStream(DataEntry dataEntry1,
 DataEntry dataEntry2)
                         throws IOException

Description copied from interface: DataEntryWriter

Returns whether the two given data entries would result in the same output stream.

Specified by:

sameOutputStream in interface DataEntryWriter

Parameters:

dataEntry1 - the first data entry.

dataEntry2 - the second data entry.

Throws:

IOException

createOutputStream

public OutputStream createOutputStream(DataEntry dataEntry)
                                throws IOException

Description copied from interface: DataEntryWriter

Creates a new output stream for writing data. The caller is responsible for closing the stream.

Specified by:

createOutputStream in interface DataEntryWriter

Parameters:

dataEntry - the data entry for which the output stream is to be created.

Returns:

the output stream. The stream may be null to indicate that the data entry should not be written.

Throws:

IOException

println

public void println(PrintWriter pw,
 String prefix)

Description copied from interface: DataEntryWriter

Prints out the structure of the data entry writer.

Specified by:

println in interface DataEntryWriter

Parameters:

pw - the print stream to which the structure should be printed.

prefix - a prefix for every printed line.

visitAnyMember

public void visitAnyMember(Clazz clazz,
 Member member)

Description copied from interface: MemberVisitor

Visits any Member instance. The more specific default implementations of this interface delegate to this method.

Specified by:

visitAnyMember in interface MemberVisitor

visitProgramMethod

public void visitProgramMethod(ProgramClass programClass,
 ProgramMethod programMethod)

Specified by:

visitProgramMethod in interface MemberVisitor

visitProgramField

public void visitProgramField(ProgramClass programClass,
 ProgramField programField)

Specified by:

visitProgramField in interface MemberVisitor
