Class LiteralInstr

java.lang.Object

org.ek9lang.compiler.ir.instructions.IRInstr

org.ek9lang.compiler.ir.instructions.LiteralInstr

All Implemented Interfaces:

INode

public final class LiteralInstr
extends IRInstr

IR instruction for loading literal/constant values. Handles string literals, numeric literals, boolean literals, etc. Uses symbol-driven approach to get correct type information.

Method Summary

Modifier and Type	Method	Description
String	getLiteralType()	Get the literal type (could be decorated for generic contexts).
String	getLiteralValue()	Get the literal value.
static LiteralInstr	objectFromLiteral(String result, String literalValue, String literalType)
static LiteralInstr	objectFromLiteral(String result, String literalValue, String literalType, DebugInfo debugInfo)	Create instruction to load a literal value as an EK9 object.
static PrimitiveLiteralInstr	primitiveFromLiteral(String result, String literalValue, String primitiveType, DebugInfo debugInfo)	Create instruction to load a literal value as a primitive (int, boolean, java.lang.String).

Method Details

objectFromLiteral

public static LiteralInstr objectFromLiteral(String result,
 String literalValue,
 String literalType,
 DebugInfo debugInfo)

Create instruction to load a literal value as an EK9 object.

This creates an actual EK9 object (Integer, String, Boolean, etc.) from the literal representation - not a raw primitive value.

Parameters:

result - Variable to store the created object

literalValue - The literal value as string

literalType - The resolved type name (could be decorated)

debugInfo - Debug information for source mapping (can be null)

Returns:

LiteralInstruction for creating the object from literal

objectFromLiteral

public static LiteralInstr objectFromLiteral(String result,
 String literalValue,
 String literalType)

primitiveFromLiteral

public static PrimitiveLiteralInstr primitiveFromLiteral(String result,
 String literalValue,
 String primitiveType,
 DebugInfo debugInfo)

Create instruction to load a literal value as a primitive (int, boolean, java.lang.String).

This creates a raw primitive value - not an EK9 object. Used for: - int: Java primitive int - boolean: Java primitive boolean - java.lang.String: Java String object (not EK9 String)

The LOAD_PRIMITIVE opcode signals the bytecode generator to use primitive literal loading (BIPUSH/SIPUSH/LDC for int, ICONST_0/1 for boolean, LDC for String) instead of creating EK9 wrapper objects.

Parameters:

result - Variable to store the primitive value

literalValue - The literal value as string

primitiveType - The primitive type name ("int", "boolean", "java.lang.String")

debugInfo - Debug information for source mapping (can be null)

Returns:

LiteralInstruction for loading the primitive value

getLiteralValue

public String getLiteralValue()

Get the literal value.

getLiteralType

public String getLiteralType()

Get the literal type (could be decorated for generic contexts).
