Method Detail

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

canNullCheck

public boolean canNullCheck()

Specified by:

canNullCheck in interface Access

getWriteKind

public Kind getWriteKind()

isCompressible

public boolean isCompressible()
