VariableExpression

public VariableExpression(ExpressionContainer container)

VariableExpression

public VariableExpression(CastExpression ce,
                          Variable variable)

VariableExpression

public VariableExpression(ExpressionContainer container,
                          Variable var)

Method Detail

getVariable

public Variable getVariable()

Specified by:

getVariable in interface HasVariable

setVariable

public void setVariable(Variable variable)

Specified by:

setVariable in interface HasVariable

onVariableUpdate

public void onVariableUpdate()

onRemove

public void onRemove()

Specified by:

onRemove in interface Expression

Overrides:

onRemove in class AbstractExpression

isDeclaration

public boolean isDeclaration()

Specified by:

isDeclaration in interface HasVariable

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".

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

getContext

public java.lang.Object getContext()

Specified by:

getContext in interface ErrorItem

getLevel

public Level getLevel()

Specified by:

getLevel in interface ErrorItem

getMessage

public java.lang.String getMessage()

Specified by:

getMessage in interface ErrorItem

isAssignable

public boolean isAssignable()

Specified by:

isAssignable in interface Expression

Overrides:

isAssignable in class AbstractExpression

visitAssignTo

public void visitAssignTo(org.objectweb.asm.MethodVisitor mv,
                          Frame frame,
                          PClass clazz)

Specified by:

visitAssignTo in interface Expression

Overrides:

visitAssignTo in class AbstractExpression
