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()

Overrides:

hashCode in class Object

computeHash

public abstract int computeHash()

Returns:

the hash

equals

public abstract boolean equals(Object obj)

Overrides:

equals in class Object

resolve

protected abstract Stream<AssemblyResolvedPatterns> resolve(AssemblyResolvedPatterns fromRight,
 Collection<AssemblyResolvedError> errors)

Generate machine (partial) code for this node

Parameters:

fromRight - the accumulated patterns thus far, from the right sibling or left-most child

errors - a place to collect error reports

Returns:

the stream of generated patterns, as accumulated
