Enum Class ConstValGen

java.lang.Object

java.lang.Enum<ConstValGen>

ghidra.pcode.emu.jit.gen.var.ConstValGen

All Implemented Interfaces:

ValGen<JitConstVal>, Serializable, Comparable<ConstValGen>, Constable

public enum ConstValGen
extends Enum<ConstValGen>
implements ValGen<JitConstVal>

The generator for a constant value.

This can load directly the requested constant as the required JVM type onto the JVM stack. It simply emits an ldc bytecode.

Method Details

values

public static ConstValGen[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static ConstValGen valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null

generateValInitCode

public void generateValInitCode(JitCodeGenerator gen,
 JitConstVal v,
 org.objectweb.asm.MethodVisitor iv)

Description copied from interface: ValGen

Prepare any class-level items required to use this variable

For example, if this represents a direct memory variable, then this can prepare a reference to the portion of the state involved, allowing it to access it readily.

Specified by:

generateValInitCode in interface ValGen<JitConstVal>

Parameters:

gen - the code generator

v - the value

iv - the constructor visitor

generateValReadCode

public JitType generateValReadCode(JitCodeGenerator gen,
 JitConstVal v,
 JitTypeBehavior typeReq,
 org.objectweb.asm.MethodVisitor rv)

Description copied from interface: ValGen

Read the value onto the stack

Specified by:

generateValReadCode in interface ValGen<JitConstVal>

Parameters:

gen - the code generator

v - the value to read

typeReq - the required type of the value

rv - the visitor for the run method

Returns:

the actual p-code type (which determines the JVM type) of the value on the stack
