Method Detail

isTrace

@Input
public boolean isTrace()

Specifies that all rules call traceIn/traceOut.

setTrace

public void setTrace(boolean trace)

isTraceLexer

@Input
public boolean isTraceLexer()

Specifies that all lexer rules call traceIn/traceOut.

setTraceLexer

public void setTraceLexer(boolean traceLexer)

isTraceParser

@Input
public boolean isTraceParser()

Specifies that all parser rules call traceIn/traceOut.

setTraceParser

public void setTraceParser(boolean traceParser)

isTraceTreeWalker

@Input
public boolean isTraceTreeWalker()

Specifies that all tree walker rules call traceIn/traceOut.

setTraceTreeWalker

public void setTraceTreeWalker(boolean traceTreeWalker)

getMaxHeapSize

@Internal
public String getMaxHeapSize()

The maximum heap size for the forked antlr process (ex: '1g').

setMaxHeapSize

public void setMaxHeapSize(String maxHeapSize)

setArguments

public void setArguments(List<String> arguments)

getArguments

@Input
public List<String> getArguments()

List of command-line arguments passed to the antlr process

Returns:

The antlr command-line arguments

getOutputDirectory

@OutputDirectory
public File getOutputDirectory()

Returns the directory to generate the parser source files into.

Returns:

The output directory.

setOutputDirectory

public void setOutputDirectory(File outputDirectory)

Specifies the directory to generate the parser source files into.

Parameters:

outputDirectory - The output directory. Must not be null.

getAntlrClasspath

@Classpath
public FileCollection getAntlrClasspath()

Returns the classpath containing the Ant ANTLR task implementation.

Returns:

The Ant task implementation classpath.

setAntlrClasspath

protected void setAntlrClasspath(FileCollection antlrClasspath)

Specifies the classpath containing the Ant ANTLR task implementation.

Parameters:

antlrClasspath - The Ant task implementation classpath. Must not be null.

getWorkerProcessBuilderFactory

@Inject
protected org.gradle.process.internal.worker.WorkerProcessFactory getWorkerProcessBuilderFactory()

execute

public void execute(IncrementalTaskInputs inputs)

setSource

public void setSource(FileTree source)

Sets the source for this task. Delegates to setSource(Object). If the source is of type SourceDirectorySet, then the relative path of each source grammar files is used to determine the relative output path of the generated source If the source is not of type SourceDirectorySet, then the generated source files end up flattened in the specified output directory.

Overrides:

setSource in class SourceTask

Parameters:

source - The source.

Since:

4.0

setSource

public void setSource(Object source)

Sets the source for this task. Delegates to SourceTask.setSource(Object). If the source is of type SourceDirectorySet, then the relative path of each source grammar files is used to determine the relative output path of the generated source If the source is not of type SourceDirectorySet, then the generated source files end up flattened in the specified output directory.

Overrides:

setSource in class SourceTask

Parameters:

source - The source.

getSource

@PathSensitive(value=RELATIVE)
public FileTree getSource()

Returns the source for this task, after the include and exclude patterns have been applied. Ignores source files which do not exist.

Overrides:

getSource in class SourceTask

Returns:

The source.
