java.lang.Object

org.apache.flex.compiler.internal.as.codegen.LexicalScope

org.apache.flex.compiler.internal.as.codegen.InlineFunctionLexicalScope

public class InlineFunctionLexicalScope
extends LexicalScope

Lexical scope which is constructed when inlining a function. This allows us to modify the lexical scope of the calling function, and if the inline fails unwind any changes which were made to the scope.

Constructor Detail

InlineFunctionLexicalScope

protected InlineFunctionLexicalScope(LexicalScope enclosingFrame,
                          IASScope containingScope,
                          boolean storeClassBinding,
                          FunctionNode functionNode)

Method Detail

assignActualsToFormals

public void assignActualsToFormals(FunctionDefinition functionDef,
                          InstructionList result)

mergeIntoContainingScope

public void mergeIntoContainingScope(InstructionList result)

insideInlineFunction

public boolean insideInlineFunction()

Description copied from class: LexicalScope

Test whether we are currently inside the scope of a function being inlined.

Overrides:

insideInlineFunction in class LexicalScope

Returns:

true if currently inside an inline function.

getThisBinding

protected Binding getThisBinding(IdentifierNode id)

Description copied from class: LexicalScope

Fetch the Binding that represents "this."

Overrides:

getThisBinding in class LexicalScope

Returns:

said Binding.

findProperty

public InstructionList findProperty(Name name,
                           IDefinition def,
                           boolean useStrict)

Description copied from class: LexicalScope

Get the property for the specified name. Use this method rather than using findprop directly, because inlining needs to do some magic

Overrides:

findProperty in class LexicalScope

Parameters:

name - Name of the property to find

def - Definition of the property to find

useStrict - Use OP_findpropstrict

Returns:

InstructionList

getPropertyValue

public InstructionList getPropertyValue(Name name,
                               IDefinition def)

Description copied from class: LexicalScope

Get the property value for the specified name. Use this method rather than using getlex directly, because inlining needs to do some magic

Overrides:

getPropertyValue in class LexicalScope

Parameters:

name - Name of the property to find

def - Definition of the property to find

Returns:

InstructionList

getProblems

public Collection<ICompilerProblem> getProblems()

Overrides:

getProblems in class LexicalScope

Returns:

the problems covering this code generation phase.

setContainingClass

public Instruction setContainingClass()

getInlinedFunctionCallSiteLabel

public Label getInlinedFunctionCallSiteLabel()

Returns the label to jump back to when returning out of an inlined function

Returns:

label, or null if not inlining a function
