Constructor Detail

ExecutionLoopCondition

public ExecutionLoopCondition(ITreeSettings settings,
                              Node proofNode)

Constructor.

Parameters:

settings - The ITreeSettings to use.

proofNode - The Node of KeY's proof tree which is represented by this IExecutionNode.

Method Detail

lazyComputeName

protected java.lang.String lazyComputeName()

Computes the name of this node lazily when AbstractExecutionElement.getName() is called the first time.

Specified by:

lazyComputeName in class AbstractExecutionElement

Returns:

The human readable name of this IExecutionNode.

getGuardExpression

public Expression getGuardExpression()

Returns the loop expression which is executed.

Specified by:

getGuardExpression in interface IExecutionLoopCondition

Returns:

The executed loop expression.

getGuardExpressionPositionInfo

public PositionInfo getGuardExpressionPositionInfo()

Returns the code position of the executed loop expression (IExecutionLoopCondition.getGuardExpression()).

Specified by:

getGuardExpressionPositionInfo in interface IExecutionLoopCondition

Returns:

The code of the executed loop expression.

lazyComputeConstraints

protected IExecutionConstraint[] lazyComputeConstraints()

Computes the constraints lazily when AbstractExecutionNode.getConstraints() is called the first time.

Specified by:

lazyComputeConstraints in class AbstractExecutionNode<JavaStatement>

Returns:

The IExecutionConstraints of the current state.

getElementType

public java.lang.String getElementType()

Returns a human readable element type name.

Specified by:

getElementType in interface IExecutionElement

Returns:

The human readable element type.
