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

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

field

public ResolvedJavaField field(int index)

getFields

public ResolvedJavaField[] getFields()

toString

public String toString(Verbosity verbosity)

Description copied from class: Node

Creates a String representation for this 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

fieldIndex

public int fieldIndex(ResolvedJavaField field)

entryIndexForOffset

public int entryIndexForOffset(MetaAccessProvider metaAccess,
                               long constantOffset,
                               JavaKind 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

constantOffset - offset, where the value is placed.

expectedEntryKind - Specifies which type is expected at this offset (Is important when

entryKind

public JavaKind entryKind(MetaAccessExtensionProvider metaAccessExtensionProvider,
                          int index)

Description copied from class: VirtualObjectNode

Returns the JavaKind of the entry at the given index.

Specified by:

entryKind in class VirtualObjectNode

duplicate

public VirtualInstanceNode 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
