AssignExpr

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

makeReference

public Expr makeReference()

Description copied from class: Expr

When called for the first time will return an expression that may involve computation and state changes. When called on an Expr returned from this method, it is guaranteed that no further computation will occur. For Exprs that are already references, this is copied identity. For others, this will return a ReferenceExpr.

Overrides:

makeReference in class Expr

walkFlow

public void walkFlow(org.aspectj.compiler.base.FlowCheckerPass w)

Overrides:

walkFlow in class BangExpr

postAssignmentCheck

public ASTObject postAssignmentCheck(org.aspectj.compiler.base.AssignmentCheckerPass walker)

Overrides:

postAssignmentCheck in class ASTObject

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

build

public static AssignExpr build(SourceLocation source,
                               AssignableExpr rand1,
                               java.lang.String op,
                               Expr rand2)

getOp

public java.lang.String getOp()

setOp

public void setOp(java.lang.String _op)

getRhs

public Expr getRhs()

setRhs

public void setRhs(Expr _rhs)

getChildAt

public ASTObject getChildAt(int childIndex)

Overrides:

getChildAt in class BangExpr

getChildNameAt

public java.lang.String getChildNameAt(int childIndex)

Overrides:

getChildNameAt in class BangExpr

setChildAt

public void setChildAt(int childIndex,
                       ASTObject child)

Overrides:

setChildAt in class BangExpr

getChildCount

public int getChildCount()

Overrides:

getChildCount in class BangExpr

getDefaultDisplayName

public java.lang.String getDefaultDisplayName()

Overrides:

getDefaultDisplayName in class BangExpr
