Method Details

values

public static JitAllocationModel.NoHandler[] 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 JitAllocationModel.NoHandler 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

type

public JitType type()

Description copied from interface: JitAllocationModel.VarHandler

Get the p-code type of the variable this handler handles.

Specified by:

type in interface JitAllocationModel.VarHandler

Returns:

the type

generateInitCode

public void generateInitCode(JitCodeGenerator gen,
 org.objectweb.asm.MethodVisitor iv)

Description copied from interface: JitAllocationModel.VarHandler

Emit bytecode into the class constructor.

Specified by:

generateInitCode in interface JitAllocationModel.VarHandler

Parameters:

gen - the code generator

iv - the visitor for the class constructor

generateDeclCode

public void generateDeclCode(JitCodeGenerator gen,
 org.objectweb.asm.Label start,
 org.objectweb.asm.Label end,
 org.objectweb.asm.MethodVisitor rv)

Description copied from interface: JitAllocationModel.VarHandler

If needed, emit bytecode at the top of the run method.

Specified by:

generateDeclCode in interface JitAllocationModel.VarHandler

Parameters:

gen - the code generator

start - a label at the top of the method

end - a label at the end of the method

rv - the visitor for the run method

generateLoadCode

public void generateLoadCode(JitCodeGenerator gen,
 JitType type,
 org.objectweb.asm.MethodVisitor rv)

Description copied from interface: JitAllocationModel.VarHandler

Emit bytecode to load the varnode's value onto the JVM stack.

Specified by:

generateLoadCode in interface JitAllocationModel.VarHandler

Parameters:

gen - the code generator

type - the p-code type of the value expected on the JVM stack by the proceeding bytecode

rv - the visitor for the run method

generateStoreCode

public void generateStoreCode(JitCodeGenerator gen,
 JitType type,
 org.objectweb.asm.MethodVisitor rv)

Description copied from interface: JitAllocationModel.VarHandler

Emit bytecode to load the varnode's value onto the JVM stack.

Specified by:

generateStoreCode in interface JitAllocationModel.VarHandler

Parameters:

gen - the code generator

type - the p-code type of the value produced on the JVM stack by the preceding bytecode

rv - the visitor for the run method
