Field Detail

pre

protected LLJava.StackFrame pre

The static stack frame precondition for this instruction. This field is set by the TypeChecker.

(This definition has been created by UMod from the source at SYSTEM "LLJava.umod":1119.9-1120.13, cf. this pretty print.)
The type of this field is LLJava.StackFrame(maybe null)
Its value defaults to null.

get_pre(), set_pre(eu.bandm.tools.lljava.absy.LLJava.StackFrame)

post

protected LLJava.StackFrame post

The static stack frame postcondition for this instruction. This field is set by the TypeChecker.

(This definition has been created by UMod from the source at SYSTEM "LLJava.umod":1123.9-1124.13, cf. this pretty print.)
The type of this field is LLJava.StackFrame(maybe null)
Its value defaults to null.

Constructor Detail

Instruction

public Instruction()

Synthetic minimal constructor provided by the umod compiler.
Constructor with minimal set of arguments, supplied automatically by the umod compiler, not explicitly by user.
(All object fields are set to their default values.)

Method Detail

doclone

public LLJava.Instruction doclone()

Clones this object. Method never fails, since Cloneable is known to be implemented.

Overrides:

doclone in class LLJava.Statement

Returns:

a fresh copy.

format

public Format format()

Delivers a format object for pretty-printing by inheritance from some ancestor class.

Specified by:

format in interface Formattable

Overrides:

format in class LLJava.Statement

initFrom

public LLJava.Instruction initFrom(Object o0)

Copies values of all common fields from the argument. All fields of this class definition are copied, iff the argument is of this class. Then the superclass method is invoked with the same argument.

Overrides:

initFrom in class LLJava.Statement

get_pre

public LLJava.StackFrame get_pre()

The static stack frame precondition for this instruction. This field is set by the TypeChecker.

(This definition has been created by UMod from the source at SYSTEM "LLJava.umod":1119.9-1120.13, cf. this pretty print.)
Generated getter method. @see #pre

Returns:

The current field value of type LLJava.StackFrame(maybe null)

set_pre

public boolean set_pre(LLJava.StackFrame val)

The static stack frame precondition for this instruction. This field is set by the TypeChecker.

(This definition has been created by UMod from the source at SYSTEM "LLJava.umod":1119.9-1120.13, cf. this pretty print.)
Updates the (mutable) instance destructively.

Parameters:

val - the new value of type LLJava.StackFrame(maybe null)

Returns:

whether a change (w.r.t. ==) did actually happen.

See Also:

pre

get_post

public LLJava.StackFrame get_post()

The static stack frame postcondition for this instruction. This field is set by the TypeChecker.

(This definition has been created by UMod from the source at SYSTEM "LLJava.umod":1123.9-1124.13, cf. this pretty print.)
Generated getter method. @see #post

Returns:

The current field value of type LLJava.StackFrame(maybe null)

set_post

public boolean set_post(LLJava.StackFrame val)

The static stack frame postcondition for this instruction. This field is set by the TypeChecker.

(This definition has been created by UMod from the source at SYSTEM "LLJava.umod":1123.9-1124.13, cf. this pretty print.)
Updates the (mutable) instance destructively.

Parameters:

val - the new value of type LLJava.StackFrame(maybe null)

Returns:

whether a change (w.r.t. ==) did actually happen.

post

get_pre

public static Pattern<LLJava.Instruction> get_pre(Pattern<? super LLJava.StackFrame> p)

Lifts a pattern which matches the field value to one which matches this whole object.
More complex pattern methods are generated in the one ancillary class LLJava.__Patterns.

get_post

public static Pattern<LLJava.Instruction> get_post(Pattern<? super LLJava.StackFrame> p)

Lifts a pattern which matches the field value to one which matches this whole object.
More complex pattern methods are generated in the one ancillary class LLJava.__Patterns.
