Enum Class DoubleReadGen

java.lang.Object

java.lang.Enum<DoubleReadGen>

ghidra.pcode.emu.jit.gen.type.DoubleReadGen

All Implemented Interfaces:

TypedAccessGen, Serializable, Comparable<DoubleReadGen>, Constable

public enum DoubleReadGen
extends Enum<DoubleReadGen>
implements TypedAccessGen

The generator for reading doubles

This is accomplished by reading a long and then converting it.

Method Details

values

public static DoubleReadGen[] 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 DoubleReadGen 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

generateCode

public void generateCode(JitCodeGenerator gen,
 Varnode vn,
 org.objectweb.asm.MethodVisitor rv)

Description copied from interface: TypedAccessGen

Emit code to access a varnode.

If reading, the result is placed on the JVM stack. If writing, the value is popped from the JVM stack.

If the varnode fits completely in the block (the common case), then this accesses the bytes from the one block, using the method chosen by size. If the varnode extends into the next block, then this will split the varnode into two portions according to machine byte order. Each portion is accessed using the method for the size of that portion. If reading, the results are reassembled into a single value and pushed onto the JVM stack.

Specified by:

generateCode in interface TypedAccessGen

Parameters:

gen - the code generator

vn - the varnode

rv - the method visitor
