InMemoryLargeSourceSet

public InMemoryLargeSourceSet(List<SourceFile> ls)

InMemoryLargeSourceSet

protected InMemoryLargeSourceSet(@Nullable
 @Nullable InMemoryLargeSourceSet initialState,
 @Nullable
 @Nullable Map<SourceFile,List<Recipe>> deletions,
 List<SourceFile> ls)

Method Details

withChanges

protected InMemoryLargeSourceSet withChanges(@Nullable
 @Nullable Map<SourceFile,List<Recipe>> deletions,
 List<SourceFile> mapped)

setRecipe

public void setRecipe(List<Recipe> recipeStack)

Description copied from interface: LargeSourceSet

Maintain context about what recipe is performing an edit or generating code.

Specified by:

setRecipe in interface LargeSourceSet

Parameters:

recipeStack - A stack rooted at the currently operating recipe and extending up its containing recipes to top-level recipe that a developer is running directly.

edit

public LargeSourceSet edit(UnaryOperator<SourceFile> map)

Description copied from interface: LargeSourceSet

Execute a transformation on all items.

Specified by:

edit in interface LargeSourceSet

Parameters:

map - A transformation on T

Returns:

A new source set if the map function results in any changes, otherwise this source set is returned.

generate

public LargeSourceSet generate(@Nullable
 @Nullable Collection<? extends SourceFile> t)

Description copied from interface: LargeSourceSet

Concatenate new items. Where possible, implementations should not iterate the entire source set in order to accomplish this, since the ordering of SourceFile is not significant.

Specified by:

generate in interface LargeSourceSet

Parameters:

t - The new item to insert

Returns:

A new source set with the new item inserted.

getInitialState

protected InMemoryLargeSourceSet getInitialState()

getChangeset

public Changeset getChangeset()

Specified by:

getChangeset in interface LargeSourceSet

Returns:

The set of changes (encompassing adds, edits, and deletions) to the initial state.

getBefore

@Nullable
public @Nullable SourceFile getBefore(Path sourcePath)

Description copied from interface: LargeSourceSet

Get the original source file, before any edits. Returns null if it is not present.

Specified by:

getBefore in interface LargeSourceSet

Parameters:

sourcePath - The path of the source file to retrieve.

Returns:

The original source file. Null if not present.
