Constructor Details

StaticImportVisitor

public StaticImportVisitor(ClassNode classNode,
 SourceUnit sourceUnit)

Creates a visitor that rewrites references resolved through static imports.

Parameters:

classNode - the class currently being transformed

sourceUnit - the source unit containing the class

Method Details

visitClass

@Deprecated
public void visitClass(ClassNode classNode,
 SourceUnit sourceUnit)

Deprecated.

Call StaticImportVisitor(ClassNode,SourceUnit) then ClassCodeVisitorSupport.visitClass(ClassNode).

visitConstructorOrMethod

protected void visitConstructorOrMethod(MethodNode node,
 boolean isConstructor)

Tracks the current method while transforming static-import references.

Overrides:

visitConstructorOrMethod in class ClassCodeExpressionTransformer

Parameters:

node - the method or constructor being visited

isConstructor - whether node is a constructor

visitAnnotations

public void visitAnnotations(AnnotatedNode node)

Marks annotation traversal so imported constants can be inlined safely.

Overrides:

visitAnnotations in class ClassCodeVisitorSupport

Parameters:

node - the annotated node whose annotations are being visited

transform

public Expression transform(Expression exp)

Rewrites expressions that may target statically imported members.

Specified by:

transform in interface ExpressionTransformer

Overrides:

transform in class ClassCodeExpressionTransformer

Parameters:

exp - the expression to transform

Returns:

the transformed expression

transformBinaryExpression

protected Expression transformBinaryExpression(BinaryExpression be)

Rewrites binary expressions that may reference statically imported members.

Parameters:

be - the binary expression to transform

Returns:

the transformed expression

transformVariableExpression

protected Expression transformVariableExpression(VariableExpression ve)

Rewrites variable expressions that resolve to statically imported fields or accessors.

Parameters:

ve - the variable expression to transform

Returns:

the transformed expression

transformMethodCallExpression

protected Expression transformMethodCallExpression(MethodCallExpression mce)

Rewrites implicit-this calls that resolve to statically imported methods or properties.

Parameters:

mce - the method call to transform

Returns:

the transformed expression

transformConstructorCallExpression

protected Expression transformConstructorCallExpression(ConstructorCallExpression cce)

Rewrites named-argument constructor calls that use statically imported members.

Parameters:

cce - the constructor call to transform

Returns:

the transformed expression

transformClosureExpression

protected Expression transformClosureExpression(ClosureExpression ce)

Rewrites default parameter expressions inside closures.

Parameters:

ce - the closure expression to transform

Returns:

the transformed expression

transformPropertyExpression

protected Expression transformPropertyExpression(PropertyExpression pe)

Rewrites property expressions that may resolve through static imports.

Parameters:

pe - the property expression to transform

Returns:

the transformed expression

getSourceUnit

protected SourceUnit getSourceUnit()

Returns the source unit currently being transformed.

Specified by:

getSourceUnit in class ClassCodeVisitorSupport

Returns:

the active source unit
