Method Detail

fixAccessToFieldSet

public ASTObject fixAccessToFieldSet(FieldAccessExpr expr)

Specified by:

fixAccessToFieldSet in class BangExpr

unparse

public void unparse(org.aspectj.compiler.base.CodeWriter writer)

Overrides:

unparse in class ASTObject

checkSpec

public void checkSpec()

Overrides:

checkSpec in class Expr

postInnerAccess

public ASTObject postInnerAccess(org.aspectj.compiler.base.InnerAccessFixer w)

Description copied from class: ASTObject

Converts an expression accessing inaccessable context to one that is legal.

Overrides:

postInnerAccess in class ASTObject

buildAccessMethod

public MethodDec buildAccessMethod(org.aspectj.compiler.base.InnerAccessFixer w)

Description copied from class: ASTObject

Builds a method that would perform the actions of this expression. The InnerAccessFixer object keeps a cache of such methods to provide to the InnerAccessFixer walk, but if no appropriate method has yet been built, the original expression is the one that knows how to build it. This should only be overridden in PrefixExpr, PostfixExpr, FieldAccessExpr, AssignExpr, and CallExpr. If and when we do cookie methods for constructor, we may also need to override this in NewInstanceExpr and ConstructorCallExpr.

Overrides:

buildAccessMethod in class ASTObject

cgValue

protected void cgValue(org.aspectj.compiler.base.bcg.CodeBuilder cb)

Description copied from class: Expr

Leaves the value of this expression on the stack. May self-call Expr.cgTest(CodeBuilder, Label, Label).

Overrides:

cgValue in class Expr

cgEffect

protected void cgEffect(org.aspectj.compiler.base.bcg.CodeBuilder cb)

Description copied from class: Expr

Evaluates the expression in a context where its value is unnecessary (i.e., from ExprStmt, or in a FieldAccessExpr when the field is static but there is an expression there nonetheless). May self-call Expr.cgValue(CodeBuilder).

Overrides:

cgEffect in class Expr

getOp

public java.lang.String getOp()

setOp

public void setOp(java.lang.String _op)

copyWalk

public ASTObject copyWalk(CopyWalker walker)

Overrides:

copyWalk in class ASTObject

getDefaultDisplayName

public java.lang.String getDefaultDisplayName()

Overrides:

getDefaultDisplayName in class BangExpr
