Constructor Detail

AddOpExpr

public AddOpExpr(SourceLocation location,
                 Expr _rand1,
                 java.lang.String _op,
                 Expr _rand2)

Method Detail

halfFold

protected LiteralExpr halfFold(Type type,
                               LiteralExpr lit1,
                               LiteralExpr lit2)

Description copied from class: BinopExpr

returns a new unfinished ASTObject, that still needs to have ASTObject.setSource(org.aspectj.compiler.base.ast.ASTObject) called on it.

Specified by:

halfFold in class BinopExpr

discoverType

protected Type discoverType()

Specified by:

discoverType in class Expr

getLiftType

protected Type getLiftType()

Specified by:

getLiftType in class BinopExpr

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

cgBuffer

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

Description copied from class: Expr

Evaluates the expression in a context where the top of the stack contains a StringBuffer object. The value of this expression is then appended into the StringBuffer. This is used in evaluating the String + operator. May self-call Expr.cgValue(CodeBuilder).

Overrides:

cgBuffer in class Expr

cgOp

protected void cgOp(org.aspectj.compiler.base.bcg.CodeBuilder cb,
                    Type ty)

Description copied from class: BinopExpr

Generate code that takes the top two values on the stack and replaces it with the one value that is appropriate. This is only used by non-effect operators, and is sometimes called from AssignExpr.

Specified by:

cgOp in class BinopExpr

copyWalk

public ASTObject copyWalk(CopyWalker walker)

Overrides:

copyWalk in class ASTObject

getDefaultDisplayName

public java.lang.String getDefaultDisplayName()

Overrides:

getDefaultDisplayName in class BinopExpr
