Constructor Detail

ExecutionBlockContract

public ExecutionBlockContract(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

getElementType

public String getElementType()

Returns a human readable element type name.

Specified by:

getElementType in interface IExecutionElement

Returns:

The human readable element type.

lazyComputeConstraints

protected IExecutionConstraint[] lazyComputeConstraints()

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

Specified by:

lazyComputeConstraints in class AbstractExecutionNode<SourceElement>

Returns:

The IExecutionConstraints of the current state.

lazyComputeName

protected String lazyComputeName()
                          throws ProofInputException

Specified by:

lazyComputeName in class AbstractExecutionElement

Returns:

The human readable name of this IExecutionNode.

Throws:

ProofInputException

declaredVariableAsTerm

protected Term declaredVariableAsTerm(StatementBlock sb,
                                      int statementIndex)
