[Groovy] Class VariableExpressionReplacer

org.codehaus.groovy.transform.tailrec.VariableExpressionReplacer

@CompileStatic
class VariableExpressionReplacer
extends CodeVisitorSupport

Tool for replacing VariableExpression instances in an AST by other VariableExpression instances. Regardless of a real change taking place in nested expressions, all considered expression (trees) will be replaced. This could be optimized to accelerate compilation. Within

TailRecursive:: it is used - to swap the access of method args with the access to iteration variables - to swap the access of iteration variables with the access of temp vars

Method Detail

void replaceIn(ASTNode root)

void visitAssertStatement(AssertStatement statement)

void visitBinaryExpression(BinaryExpression expression)

It's the only Expression type in which replacing is considered. That's an abuse of the class, but I couldn't think of a better way.

void visitCaseStatement(CaseStatement statement)

void visitDoWhileLoop(DoWhileStatement loop)

void visitExpressionStatement(ExpressionStatement statement)

void visitForLoop(ForStatement forLoop)

void visitSwitch(SwitchStatement statement)

void visitSynchronizedStatement(SynchronizedStatement statement)

void visitThrowStatement(ThrowStatement statement)
