Class FilterIncrementalFileMergerInput

java.lang.Object

com.android.builder.merge.DelegateIncrementalFileMergerInput

com.android.builder.merge.FilterIncrementalFileMergerInput

All Implemented Interfaces:

IncrementalFileMergerInput, OpenableCloseable

public class FilterIncrementalFileMergerInput
extends DelegateIncrementalFileMergerInput

IncrementalFileMergerInput that filters input based on a predicate over the accepted paths. This input will effectively create a view with a subset of another input.

Constructor Detail

FilterIncrementalFileMergerInput

public FilterIncrementalFileMergerInput(@NonNull
                                        IncrementalFileMergerInput input,
                                        @NonNull
                                        java.util.function.Predicate<java.lang.String> pathsAccepted)

Creates a new incremental input based on another input filtering all files whose OS-independent path are not accepted by the provided predicate.

Parameters:

input - the input to filter

pathsAccepted - predicate that accepts only paths that should be in the output

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

Overrides:

getUpdatedPaths in class DelegateIncrementalFileMergerInput

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

Overrides:

getAllPaths in class DelegateIncrementalFileMergerInput

Returns:

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

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

Overrides:

getFileStatus in class DelegateIncrementalFileMergerInput

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

Overrides:

openPath in class DelegateIncrementalFileMergerInput

Parameters:

path - the path

Returns:

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