インタフェース IncrementalTaskInputs

@Incubating
 @NonExtensible
public interface IncrementalTaskInputs

Provides access to any input files that need to be processed by an incremental task.

An incremental task action is one that accepts a single IncrementalTaskInputs parameter. The task can then provide an action to execute for all input files that are out of date with respect to the previous execution of the task, and a separate action for all input files that have been removed since the previous execution.

 class IncrementalReverseTask extends DefaultTask {

boolean	isIncremental() Indicates if it was possible for Gradle to determine which exactly which input files were out of date compared to a previous execution.
void	outOfDate(Action<? super InputFileDetails> outOfDateAction) Executes the action for all of the input files that are out-of-date since the previous task execution.

メソッドの詳細

isIncremental

boolean isIncremental()

Indicates if it was possible for Gradle to determine which exactly which input files were out of date compared to a previous execution. This is not possible in the case of no previous execution, changed Input Properties, Output Files, etc.

When true:

• Any input file that has been added or modified since previous execution will be considered 'out-of-date' and reported to outOfDate(org.gradle.api.Action<? super org.gradle.api.tasks.incremental.InputFileDetails>).
• Any input files that has been removed since previous execution will be reported to removed(org.gradle.api.Action<? super org.gradle.api.tasks.incremental.InputFileDetails>).

When false:

• Every input file will be considered to be 'out-of-date' and will be reported to outOfDate(org.gradle.api.Action<? super org.gradle.api.tasks.incremental.InputFileDetails>).
• No input files will be reported to removed(org.gradle.api.Action<? super org.gradle.api.tasks.incremental.InputFileDetails>).

outOfDate

void outOfDate(Action<? super InputFileDetails> outOfDateAction)

Executes the action for all of the input files that are out-of-date since the previous task execution. The action may also be supplied as a Closure.

• When isIncremental() == true, the action will be executed for any added or modified input file.
• When isIncremental() == false, the action will be executed for every input file for the task.

This method may only be called a single time for a single IncrementalTaskInputs instance.

例外:

IllegalStateException - on second and subsequent invocations.

removed

void removed(Action<? super InputFileDetails> removedAction)

Executes the action for all of the input files that were removed since the previous task execution. The action may also be supplied as a Closure.

• When isIncremental() == true, the action will be executed for any removed input file.
• When isIncremental() == false, the action will not be executed.

This method may only be called a single time for a single IncrementalTaskInputs instance.

This method may only be called after outOfDate(org.gradle.api.Action<? super org.gradle.api.tasks.incremental.InputFileDetails>) has been called.

例外:

IllegalStateException - if invoked prior to outOfDate(org.gradle.api.Action<? super org.gradle.api.tasks.incremental.InputFileDetails>), or if invoked more than once.
