makeRecursiveCopy

public ParseTree makeRecursiveCopy()

Description copied from interface: ParseTree

Makes a new copy (another object) of this nonleaf-node recursively. The objects contained by this object will also be copied.

Specified by:

makeRecursiveCopy in interface ParseTree

Overrides:

makeRecursiveCopy in class NonLeaf

makeCopy

public ParseTree makeCopy()

Description copied from interface: ParseTree

Makes a new copy of this nonleaf-node as a ptree-node. The objects contained by the new object are same as these contained by the original object.

Specified by:

makeCopy in interface ParseTree

Overrides:

makeCopy in class ParseTreeObject

getExpression

public Expression getExpression()

Gets the expression operated in this expression.

setExpression

setOperator

public void setOperator(int opr)

Sets the operator of this unary expression.

isPostfix

public boolean isPostfix()

Tests if the operator of unary expression is a postfix operator.

isPrefix

public boolean isPrefix()

Tests if the operator of unary expression is a prefix operator.
