public class IRBindingEvalScript
extends IREvalScript

Explicit Binding Evals must allow preserving values between evals. They do this is a special hidden scope.

Constructor Detail

IRBindingEvalScript

public IRBindingEvalScript(IRManager manager,
                   IRScope lexicalParent,
                   String fileName,
                   int lineNumber,
                   StaticScope staticScope,
                   EvalType evalType)

Method Detail

lookupExistingLVar

public LocalVariable lookupExistingLVar(String name)

Overrides:

lookupExistingLVar in class IRScope

findExistingLocalVariable

protected LocalVariable findExistingLocalVariable(String name,
                                      int scopeDepth)

Overrides:

findExistingLocalVariable in class IRClosure

getLocalVariable

public LocalVariable getLocalVariable(String name,
                             int scopeDepth)

Description copied from class: IRScope

Find or create a local variable. By default, scopes are assumed to only check current depth. Blocks/Closures override this because they have special nesting rules.

Overrides:

getLocalVariable in class IRClosure

getNewLocalVariable

public LocalVariable getNewLocalVariable(String name,
                                int depth)

Overrides:

getNewLocalVariable in class IRClosure

getNewFlipStateVariable

public LocalVariable getNewFlipStateVariable()

Overrides:

getNewFlipStateVariable in class IREvalScript

getUsedVariablesCount

public int getUsedVariablesCount()

Overrides:

getUsedVariablesCount in class IRScope
