Constructor Detail

AccessFieldNode

public AccessFieldNode(NodeClass<? extends AccessFieldNode> c,
                       Stamp stamp,
                       ValueNode object,
                       ResolvedJavaField field)

Constructs a new access field object.

Parameters:

object - the instruction producing the receiver object

field - the compiler interface representation of the field

Method Detail

object

public ValueNode object()

field

public ResolvedJavaField field()

Gets the compiler interface field for this field access.

Returns:

the compiler interface field for this field access

isStatic

public boolean isStatic()

Checks whether this field access is an access to a static field.

Returns:

true if this field access is to a static field

isVolatile

public boolean isVolatile()

Checks whether this field is declared volatile.

Returns:

true if the field is resolved and declared volatile

lower

public void lower(LoweringTool tool)

Description copied from interface: Lowerable

Expand this node into lower level nodes expressing the same semantics. If the introduced nodes are themselves lowerable, they should be recursively lowered as part of this call.

Specified by:

lower in interface Lowerable

toString

public String toString(Verbosity verbosity)

Description copied from class: Node

Creates a String representation for this node with a given Verbosity.

Overrides:

toString in class Node

verify

public boolean verify()

Overrides:

verify in class FixedNode
