Method Detail

initClassFieldMap

protected FieldMap initClassFieldMap()

Overrides:

initClassFieldMap in class TreeBuilder

getClassFieldMap

protected FieldMap getClassFieldMap()

objectSize

public int objectSize(HClass hc)

Description copied from class: Runtime.TreeBuilder

Utility method for external analyses that want to know the exact size of an object. This returns the size in bytes not including the header.

Overrides:

objectSize in class TreeBuilder

objAlloc

                    Exp length)

Overrides:

_claz_

protected Exp _claz_(TreeFactory tf,
                     HCodeElement source,
                     DerivationGenerator dg,
                     Translation.Exp objectref)

Description copied from class: TreeBuilder

Returns a pointer to the claz structure associated with the given objectref.
