public class StaticCompilationTransformer
extends ClassCodeExpressionTransformer

Some expressions use symbols as aliases to method calls (<<, +=, ...). In static compilation, if such a method call is found, we transform the original binary expression into a method call expression so that the call gets statically compiled.

Constructor Details

StaticCompilationTransformer

public StaticCompilationTransformer(SourceUnit unit,
 StaticTypeCheckingVisitor visitor)

Creates a static compilation transformer for the supplied source unit and visitor.

Parameters:

unit - the source unit being transformed

visitor - the visitor providing type-checking metadata

Method Details

getSourceUnit

protected SourceUnit getSourceUnit()

Returns the source unit currently being transformed.

Specified by:

getSourceUnit in class ClassCodeVisitorSupport

the active source unit

getTypeChooser

public StaticTypesTypeChooser getTypeChooser()

Returns the type chooser used by this transformer.

Returns:

the static types type chooser

getClassNode

public ClassNode getClassNode()

Returns the class currently enclosing the transformation context.

Returns:

the current enclosing class node

visitClassCodeContainer

public void visitClassCodeContainer(Statement code)

Visits a statement container within the current class or method.

Overrides:

visitClassCodeContainer in class ClassCodeVisitorSupport

Parameters:

code - the code container to visit

transform

public Expression transform(Expression expr)

Dispatches expression transformation to the specialized helper for the expression type.

Specified by:

Overrides:

transform in class ClassCodeExpressionTransformer

Parameters:

expr - the expression to transform

Returns:

the transformed expression

visitClass

public void visitClass(ClassNode node)

Visits a class and then recursively visits its inner classes.

Specified by:

visitClass in interface GroovyClassVisitor

Overrides:

visitClass in class ClassCodeVisitorSupport

Parameters:
