Method Detail

getSym

public Sym getSym()

Description copied from interface: IR

getSym Get the symbol represented by "this" node if this is a node representing a symbol (simple variable, element/field name, subprogram, label, constant, etc.).

Specified by:

getSym in interface IR

Overrides:

getSym in class ExpImpl

Returns:

the symbol attached to the node (either Var, Subp, Label, Elem, or Field).

getSymNodeSym

public Sym getSymNodeSym()

Description copied from interface: SymNode

getSymNodeSym

  Get the symbol attached as its symbol attribute.
  The correspondence between nodes and its symbol attribute is as follows:
    SubpNode    Subp
    VarNode     Var
    ElemNode    Elem
    ConstNode   Const
    TypeNode    Type
    LabelDef    Label
    LabelNode   Label
    SymNode     Program name if this node represents program symbol. 
                There may be other symbol when HIR is expanded.


Specified by:
getSymNodeSym in interface SymNode



Returns:
the symbol attached as its symbol attribute.

setSymNodeSym

public void setSymNodeSym(Sym pSym)

Description copied from interface: SymNode

setSymNodSym Set pSym as the symbol of this node. (Unnecessary to use this method except for modifying HIR because symNode method sets it.)

Specified by:

setSymNodeSym in interface SymNode

toString

public java.lang.String toString()

Description copied from interface: HIR

toString Get text representation of this node without traversing children.

Specified by:

toString in interface HIR

Overrides:

toString in class HIR_Impl

toStringShort

public java.lang.String toStringShort()

Description copied from interface: HIR

toStringShort Get text string of this node showing node name and index only.

Specified by:

toStringShort in interface HIR

Overrides:

toStringShort in class HIR_Impl

getIrName

public java.lang.String getIrName()

Description copied from interface: HIR

getIrName Get operation name and node index to display node in compact form for flow analysis, debug, etc.

Specified by:

getIrName in interface HIR

Overrides:

getIrName in class HIR_Impl

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

Description copied from class: HIR_Impl

clone Override Object.clone in HIR.

Overrides:

clone in class HIR_Impl

Returns:

cloned HIR object.

Throws:

java.lang.CloneNotSupportedException

accept

public void accept(HirVisitor pVisitor)

Description copied from interface: HIR0

accept Acceptor used in HIR visitor. See HirVisitor, HirVisitorModel1, HirVisitormodel2.

Specified by:

accept in interface HIR0

Overrides:

accept in class ExpImpl
