GroovyClassVisitor, GroovyCodeVisitor, ErrorCollecting

Enclosing class:

StaticTypeCheckingVisitor

protected class StaticTypeCheckingVisitor.VariableExpressionTypeMemoizer
extends ClassCodeVisitorSupport

Memoizes inferred variable types so they can be restored after temporary rewrites.

Constructor Summary

Constructors

Constructor	Description
VariableExpressionTypeMemoizer(Map<VariableExpression,ClassNode> varOrigType)	Creates a memoizer that records all visible variable expressions.
VariableExpressionTypeMemoizer(Map<VariableExpression,ClassNode> varOrigType, boolean onlySharedVariables)	Creates a memoizer with optional filtering for shared variables only.

Method Summary

Modifier and Type	Method	Description
protected SourceUnit	getSourceUnit()	Provides access to the SourceUnit for error reporting during visitation.
void	visitDeclarationExpression(DeclarationExpression expression)	Visits a DeclarationExpression with annotation processing, traversing expression annotations before delegating to parent traversal.
void	visitVariableExpression(VariableExpression expression)	Visits a VariableExpression.

Constructor Details

VariableExpressionTypeMemoizer

public VariableExpressionTypeMemoizer(Map<VariableExpression,ClassNode> varOrigType)

Creates a memoizer that records all visible variable expressions.

VariableExpressionTypeMemoizer

public VariableExpressionTypeMemoizer(Map<VariableExpression,ClassNode> varOrigType,
 boolean onlySharedVariables)

Creates a memoizer with optional filtering for shared variables only.

Method Details

getSourceUnit

protected SourceUnit getSourceUnit()

Provides access to the SourceUnit for error reporting during visitation. Implementations must override this method.

Specified by:

getSourceUnit in class ClassCodeVisitorSupport

Returns:

the source unit for this visitor

visitVariableExpression

public void visitVariableExpression(VariableExpression expression)

Visits a VariableExpression. No traversal is performed as variable expressions contain no child expressions.

Specified by:

visitVariableExpression in interface GroovyCodeVisitor

Overrides:

visitVariableExpression in class CodeVisitorSupport

Parameters:

expression - the variable expression

visitDeclarationExpression

public void visitDeclarationExpression(DeclarationExpression expression)

Visits a DeclarationExpression with annotation processing, traversing expression annotations before delegating to parent traversal.

Specified by:

visitDeclarationExpression in interface GroovyCodeVisitor

Overrides:

visitDeclarationExpression in class ClassCodeVisitorSupport

Parameters:

expression - the declaration expression to visit
