Method Detail

toExpr

public Expr toExpr()

canBeCopied

public boolean canBeCopied()

Description copied from class: Expr

Can this expression be copied without changing the semantics of the program.

Overrides:

canBeCopied in class Expr

isUltimatelyLiteral

public boolean isUltimatelyLiteral()

Description copied from class: Expr

Is this expression ultimately a literal expression. The only difference between this and canBeCopied is that 'this' is NOT ultimatelyLiteral, and that a cast is only copiable if its expression is ultimatelyLiteral.

Overrides:

isUltimatelyLiteral in class Expr

isPossibleCast

public boolean isPossibleCast()

checkSpec

public void checkSpec()

Overrides:

checkSpec in class Expr

discoverType

public Type discoverType()

Specified by:

discoverType in class Expr

unparse

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

Overrides:

unparse 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

postAssignmentCheck

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

Overrides:

postAssignmentCheck in class ASTObject

getTypeD

public TypeD getTypeD()

setTypeD

public void setTypeD(TypeD _typeD)

getExpr

public Expr getExpr()

setExpr

public void setExpr(Expr _expr)

copyWalk

public ASTObject copyWalk(CopyWalker walker)

Overrides:

copyWalk in class ASTObject

getChildAt

public ASTObject getChildAt(int childIndex)

Overrides:

getChildAt in class ASTObject

getChildNameAt

public java.lang.String getChildNameAt(int childIndex)

Overrides:

getChildNameAt in class ASTObject

setChildAt

public void setChildAt(int childIndex,
                       ASTObject child)

Overrides:

setChildAt in class ASTObject

getChildCount

public int getChildCount()

Overrides:

getChildCount in class ASTObject

getDefaultDisplayName

public java.lang.String getDefaultDisplayName()

Overrides:

getDefaultDisplayName in class Expr
