Method Detail

toExpr

public Expr toExpr()

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

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

checkSpec

public void checkSpec()

Overrides:

checkSpec in class Expr

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

getTypeD

public TypeD getTypeD()

setTypeD

public void setTypeD(TypeD _typeD)

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
