Class ParameterizedOperationDetailContextOrError

java.lang.Object

org.ek9lang.compiler.phase7.support.ParameterizedOperationDetailContextOrError

All Implemented Interfaces:

BiFunction<MethodSymbol, EK9Parser.AggregatePartsContext, EK9Parser.OperationDetailsContext>

public class ParameterizedOperationDetailContextOrError
extends Object
implements BiFunction<MethodSymbol, EK9Parser.AggregatePartsContext, EK9Parser.OperationDetailsContext>

Locates the Operation details context for a parameterized method by matching sourceToken identity.

Unlike OperationDetailContextOrError which matches by symbol identity, this class matches by sourceToken identity. This is necessary because when TypeSubstitution clones methods from the generic type to the parameterized type, the sourceToken is preserved (same object reference). See Symbol.java:157 - setSourceToken(this.getSourceToken()).

This enables matching parameterized methods (which are clones with substituted types) back to their original AST context in the generic type's ParsedModule.

Constructor Details

ParameterizedOperationDetailContextOrError

public ParameterizedOperationDetailContextOrError(ParsedModule genericParsedModule)

Create a matcher that uses the generic type's ParsedModule for AST context lookups.

Parameters:

genericParsedModule - The ParsedModule of the generic type (has the ANTLR AST)

Method Details

apply

public EK9Parser.OperationDetailsContext apply(MethodSymbol parameterizedMethod,
 EK9Parser.AggregatePartsContext ctx)

Specified by:

apply in interface BiFunction<MethodSymbol, EK9Parser.AggregatePartsContext, EK9Parser.OperationDetailsContext>

hasOperationDetails

public boolean hasOperationDetails(MethodSymbol parameterizedMethod,
 EK9Parser.AggregatePartsContext ctx)

Check if a method has operation details (a body) in the parse context. Methods declared with 'default' keyword or synthetic methods have no body.

Parameters:

parameterizedMethod - The parameterized method to check

ctx - The aggregate parts context from the generic type

Returns:

true if the method has a body (operationDetails), false otherwise
