Field Details

pre

@Opt
protected @Opt 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":1121.9-1122.13, see 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

@Opt
protected @Opt 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":1125.9-1126.13, see this pretty print.)
The type of this field is LLJava.StackFrame(maybe null)
Its value defaults to null.

Constructor Details

Instruction

public Instruction()

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

Method Details

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

Returns:

a format that represents this object in a pretty-printable way

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

@Opt
public @Opt 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":1121.9-1122.13, see this pretty print.)
Generated getter method.

Returns:

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

See Also:

• pre

set_pre

public boolean set_pre(@Opt
 @Opt 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":1121.9-1122.13, see 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

@Opt
public @Opt 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":1125.9-1126.13, see this pretty print.)
Generated getter method.

Returns:

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

See Also:

• post

set_post

public boolean set_post(@Opt
 @Opt 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":1125.9-1126.13, see 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:

• post

get_pre

public static Pattern<LLJava.Instruction> get_pre(Pattern<? super @Opt 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 @Opt 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.
