Class LazyIncrementalFileMergerInput

java.lang.Object

com.android.builder.merge.LazyIncrementalFileMergerInput

All Implemented Interfaces:

IncrementalFileMergerInput, OpenableCloseable

public class LazyIncrementalFileMergerInput
extends java.lang.Object
implements IncrementalFileMergerInput

Implementation of an IncrementalFileMergerInput that lazily loads required data.

In general, this is constructed not directly using the constructor (which absolutely can be used), but using the factory methods in LazyIncrementalFileMergerInputs.

                                      @NonNull
                                      com.android.tools.build.apkzlib.utils.CachedSupplier<com.google.common.collect.ImmutableSet<RelativeFile>> files)

Creates a new input.

Parameters:

name - the input name

updates - the file and how they were updated

files - all files

Method Detail

getUpdatedPaths

@NonNull
public com.google.common.collect.ImmutableSet<java.lang.String> getUpdatedPaths()

Description copied from interface: IncrementalFileMergerInput

Obtains all OS-independent paths of all files that were changed in this input.

Specified by:

getUpdatedPaths in interface IncrementalFileMergerInput

Returns:

the paths, may be empty if no paths were changed

getAllPaths

@NonNull
public com.google.common.collect.ImmutableSet<java.lang.String> getAllPaths()

Description copied from interface: IncrementalFileMergerInput

Obtains all OS-independent paths of all files that in this input, regardless of being changed or not.

Specified by:

getAllPaths in interface IncrementalFileMergerInput

Returns:

the paths, may be empty if the relative tree of this input is empty

getName

@NonNull
public java.lang.String getName()

Description copied from interface: IncrementalFileMergerInput

Obtains the name of this input.

Specified by:

getName in interface IncrementalFileMergerInput

Returns:

the name

getFileStatus

@Nullable
public com.android.ide.common.resources.FileStatus getFileStatus(@NonNull
                                                                           java.lang.String path)

Description copied from interface: IncrementalFileMergerInput

Obtains the status of a path in this input.

Specified by:

getFileStatus in interface IncrementalFileMergerInput

Parameters:

path - the OS-independent path; the path may or not exist in the input

Returns:

the status of the path or null if the path does not exist in the input or if the path has not been changed; null is returned if and only if !getUpdatedPaths().contains(path)

openPath

@NonNull
public java.io.InputStream openPath(@NonNull
                                             java.lang.String path)

Description copied from interface: IncrementalFileMergerInput

Opens a path for reading. This method should only be called when the input is open.

Specified by:

openPath in interface IncrementalFileMergerInput

Parameters:

path - the path

Returns:

the input stream that should be closed by the caller before OpenableCloseable.close() is called

open

public void open()

Description copied from interface: OpenableCloseable

Opens the object.

Specified by:

open in interface OpenableCloseable

close

public void close()

Description copied from interface: OpenableCloseable

Closes the object.

Specified by:

close in interface OpenableCloseable
