                        int length)

VirtualArrayNode

protected VirtualArrayNode(NodeClass<? extends VirtualObjectNode> c,

Method Detail

type

public ResolvedJavaType type()

Description copied from class: VirtualObjectNode

The type of object described by this VirtualObjectNode. In case of arrays, this is the array type (and not the component type).

Specified by:

type in class VirtualObjectNode

componentType

public ResolvedJavaType componentType()

entryCount

public int entryCount()

Description copied from class: VirtualObjectNode

The number of entries this virtual object has. Either the number of fields or the number of array elements.

Specified by:

entryCount in class VirtualObjectNode

generate

public void generate(NodeLIRBuilderTool gen)

Specified by:

generate in interface LIRLowerable

Overrides:

generate in class VirtualObjectNode

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

entryName

public String entryName(int index)

Description copied from class: VirtualObjectNode

Returns the name of the entry at the given index. Only used for debugging purposes.

Specified by:

entryName in class VirtualObjectNode

entryIndexForOffset

public int entryIndexForOffset(long constantOffset,
                               Kind expectedEntryKind)

Description copied from class: VirtualObjectNode

If the given index denotes an entry in this virtual object, the index of this entry is returned. If no such entry can be found, this method returns -1.

Specified by:

entryIndexForOffset in class VirtualObjectNode

Parameters:

constantOffset - offset, where the value is placed.

expectedEntryKind - Specifies which type is expected at this offset (Is important when doing implicit casts, especially on big endian systems.

entryIndexForOffset

public static int entryIndexForOffset(long constantOffset,
                                      Kind expectedEntryKind,
                                      ResolvedJavaType componentType,
                                      int length)

entryKind

public Kind entryKind(int index)

Description copied from class: VirtualObjectNode

Returns the Kind of the entry at the given index.

Specified by:

entryKind in class VirtualObjectNode

duplicate

public VirtualArrayNode duplicate()

Description copied from class: VirtualObjectNode

Returns an exact duplicate of this virtual object node, which has not been added to the graph yet.

Specified by:

duplicate in class VirtualObjectNode

getMaterializedRepresentation

public ValueNode getMaterializedRepresentation(FixedNode fixed,
                                               ValueNode[] entries,
                                               LockState locks)

Description copied from class: VirtualObjectNode

Returns a node that can be used to materialize this virtual object. If this returns an AllocatedObjectNode then this node will be attached to a CommitAllocationNode , otherwise the node will just be added to the graph.

Specified by:

getMaterializedRepresentation in class VirtualObjectNode

length

public ValueNode length()

Specified by:

length in interface ArrayLengthProvider

Returns:

the length of the array described by this node, or null if it is not available
