Method Detail

visit

public void visit(org.objectweb.asm.MethodVisitor mv,
                  Frame frame,
                  PClass clazz,
                  boolean forAssignment)

Specified by:

visit in interface Expression

forAssignment - This indicates that the expression is evaluated to be assigned a value. In this case the last element should not be evaluated (e.g. obj.name should only push obj onto the stack, but to the value of "name".

setDereferenced

public void setDereferenced(Expression dereferenced)

setExpression

public void setExpression(Expression expression)

getDereferenced

public Expression getDereferenced()

getExpression

public Expression getExpression()

replaceChild

public void replaceChild(Expression child,
                         Expression newChild)

Specified by:

replaceChild in interface ExpressionContainer

getResultType

public PType getResultType()

Specified by:

getResultType in interface Expression

toString

public java.lang.String toString(java.lang.String indent)

Specified by:

toString in interface Expression

public void removeChild(Expression child)

Specified by:

removeChild in interface ExpressionContainer

public boolean containsChild(Expression expression)

Specified by:

containsChild in interface ExpressionContainer

                      throws ConstraintViolationException

Specified by:

                          Frame frame,
                          PClass clazz)

Specified by:

visitAssignTo in interface Expression

Overrides:

visitAssignTo in class AbstractExpression
