AbstractAssemblyState

protected AbstractAssemblyState(AbstractAssemblyTreeResolver<?> resolver,
 List<AssemblyConstructorSemantic> path,
 int shift,
 int length)

Construct a node

Parameters:

resolver - the resolver

path - the path to this node for diagnostics

shift - the (right) shift in bytes for this operand

length - the length of this operand

Method Details

hashCode

public int hashCode()
