public final class CallGraphCollector
extends ScopeStackConsistencyListener

Collects call graph information during AST traversal in Phase 5 (PRE_IR_CHECKS).

This listener walks the AST and populates a shared CallGraph with:

• Callable registrations (functions, methods, programs, operators)
• Call edges (caller → callee relationships)
• Allocated types (for RTA filtering of polymorphic calls)
• Assertion locations (for E81007 and orphan detection)

Thread-safe: Uses a shared CallGraph with ConcurrentHashMap internals. Multiple instances can process different source files in parallel.

Description copied from class: EK9BaseListener

Enter a parse tree produced by EK9Parser.expression().

The default implementation does nothing.

Specified by:

enterExpression in interface EK9Listener

Overrides:

enterExpression in class EK9BaseListener

Parameters:

ctx - the parse tree

enterTryStatementExpression

public void enterTryStatementExpression(EK9Parser.TryStatementExpressionContext ctx)

Description copied from class: EK9BaseListener

The default implementation does nothing.

Specified by:

enterTryStatementExpression in interface EK9Listener

Overrides:

enterTryStatementExpression in class ScopeStackConsistencyListener

Parameters:

ctx - the parse tree

enterVariableOnlyDeclaration

public void enterVariableOnlyDeclaration(EK9Parser.VariableOnlyDeclarationContext ctx)

An injection in a callable's body is recorded against that callable, so DI completeness can follow it from every program that reaches it. A PROPERTY's injection is not: it belongs to its type and is required wherever the type is constructed - which DI completeness follows through the construction - not wherever the type is declared (a dynamic class's properties sit inside the function declaring it).

Specified by:

enterVariableOnlyDeclaration in interface EK9Listener

Overrides:

enterVariableOnlyDeclaration in class EK9BaseListener

Parameters:

ctx - the parse tree

exitIdentifierReference

public void exitIdentifierReference(EK9Parser.IdentifierReferenceContext ctx)

A function named but not called here - an argument, an assignment to a delegate - can be called through that delegate once this callable has run. Recorded as a value reference, never a call edge (see CallGraph.getValueReferences(String)). A call's own name records one too, which adds nothing: the call edge already reaches it.

Specified by:

exitIdentifierReference in interface EK9Listener

Overrides:

exitIdentifierReference in class EK9BaseListener

Parameters:

ctx - the parse tree

exitPipelinePart

public void exitPipelinePart(EK9Parser.PipelinePartContext ctx)

A stream stage naming a function (| map with toText) - the stream calls it, no call site does.

Specified by:

exitPipelinePart in interface EK9Listener

Overrides:

exitPipelinePart in class EK9BaseListener

Parameters:

ctx - the parse tree

exitStreamExpressionTermination

public void exitStreamExpressionTermination(EK9Parser.StreamExpressionTerminationContext ctx)

| collect as T constructs T() where the pipeline is written - phase 3 has already required that constructor to exist and be accessible here (E07835) - with no call written in the source. It is recorded as the construction it is, through the same route as a written T(), so dead-code and DI analysis see the constructor (and whatever it calls) as used.

Specified by:

exitStreamExpressionTermination in interface EK9Listener

Overrides:

exitStreamExpressionTermination in class EK9BaseListener

Parameters:

ctx - the parse tree

enterAssertStatement

public void enterAssertStatement(EK9Parser.AssertStatementContext ctx)

Overrides:

enterAssertStatement in class EK9BaseListener

Parameters:

ctx - the parse tree

enterAssertThrowsExpression

public void enterAssertThrowsExpression(EK9Parser.AssertThrowsExpressionContext ctx)

Overrides:

enterAssertThrowsExpression in class EK9BaseListener

Parameters:

ctx - the parse tree

enterAssertDoesNotThrowExpression

public void enterAssertDoesNotThrowExpression(EK9Parser.AssertDoesNotThrowExpressionContext ctx)

Description copied from class: EK9BaseListener
