java.lang.Object
org.codehaus.groovy.ast.CodeVisitorSupport
org.codehaus.groovy.ast.ClassCodeVisitorSupport
org.codehaus.groovy.transform.stc.StaticTypeCheckingVisitor.VariableExpressionTypeMemoizer

All Implemented Interfaces:
  `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

  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.

  `protected SourceUnit`
  `getSourceUnit()`
  Provides access to the `SourceUnit` for error reporting during visitation.
  `void`
  `visitDeclarationExpression(DeclarationExpression expression)`

- ## 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
