Record Class DispatchTableDetails.DispatchEntry

java.lang.Object

java.lang.Record

org.ek9lang.compiler.ir.data.DispatchTableDetails.DispatchEntry

Record Components:

concreteTypeFqns - 1 FQN (single-param) or 2 FQNs (two-param) for exact type matching

handlerParamTypeFqns - Handler's declared parameter type FQNs (for CHECKCAST target)

handlerParamIsTraits - True if handler param is a trait (INVOKEINTERFACE), false for class (INVOKEVIRTUAL)

handlerMethodName - Handler method name (same as dispatcher method name)

handlerDeclaringTypeFqn - FQN of the aggregate that DECLARES the winning handler body. This is the dispatcher's own type when the handler is defined locally, but a SUPERTYPE when the handler is inherited (a concrete class commonly overrides an abstract dispatcher entry point while inheriting its typed handlers). The JVM emits INVOKEVIRTUAL selfType and lets the vtable resolve the inherited handler at runtime, so it ignores this field; a flat-symbol backend (LLVM) has no such resolution and MUST mangle the call against the declaring type, else it references a never-emitted selfType::handler symbol (finding: inheritedHandlerDispatcher native leg).

Enclosing class:

DispatchTableDetails

public static record DispatchTableDetails.DispatchEntry(List<String> concreteTypeFqns, List<String> handlerParamTypeFqns, List<Boolean> handlerParamIsTraits, String handlerMethodName, String handlerDeclaringTypeFqn)
extends Record

A single entry in the dispatch table mapping concrete type(s) to a handler method.

Constructor Details

DispatchEntry

public DispatchEntry(List<String> concreteTypeFqns,
 List<String> handlerParamTypeFqns,
 List<Boolean> handlerParamIsTraits,
 String handlerMethodName,
 String handlerDeclaringTypeFqn)

Creates an instance of a DispatchEntry record class.

Parameters:

concreteTypeFqns - the value for the concreteTypeFqns record component

handlerParamTypeFqns - the value for the handlerParamTypeFqns record component

handlerParamIsTraits - the value for the handlerParamIsTraits record component

handlerMethodName - the value for the handlerMethodName record component

handlerDeclaringTypeFqn - the value for the handlerDeclaringTypeFqn record component

Method Details

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

concreteTypeFqns

public List<String> concreteTypeFqns()

Returns the value of the concreteTypeFqns record component.

Returns:

the value of the concreteTypeFqns record component

handlerParamTypeFqns

public List<String> handlerParamTypeFqns()

Returns the value of the handlerParamTypeFqns record component.

Returns:

the value of the handlerParamTypeFqns record component

handlerParamIsTraits

public List<Boolean> handlerParamIsTraits()

Returns the value of the handlerParamIsTraits record component.

Returns:

the value of the handlerParamIsTraits record component

handlerMethodName

public String handlerMethodName()

Returns the value of the handlerMethodName record component.

Returns:

the value of the handlerMethodName record component

handlerDeclaringTypeFqn

public String handlerDeclaringTypeFqn()

Returns the value of the handlerDeclaringTypeFqn record component.

Returns:

the value of the handlerDeclaringTypeFqn record component
