/**
|
|
* This file represents the specification for CHC predicate sorts.
|
|
* Types of predicates:
|
|
*
|
|
* 1. Interface
|
|
* The idle state of a contract. Signature:
|
|
* interface(this, cryptoFunctions, blockchainState, stateVariables).
|
|
*
|
|
* 2. Nondet interface
|
|
* The nondeterminism behavior of a contract. Signature:
|
|
* nondet_interface(blockchainState, stateVariables, blockchainState', stateVariables').
|
|
*
|
|
* 3. Implicit constructor
|
|
* The implicit constructor of a contract, that is, without input parameters. Signature:
|
|
* implicit_constructor(error, this, cryptoFunctions, txData, blockchainState).
|
|
*
|
|
* 4. Constructor entry/summary
|
|
* The summary of an implicit constructor. Signature:
|
|
* constructor_summary(error, this, cryptoFunctions, txData, blockchainState, blockchainState', stateVariables').
|
|
*
|
|
* 5. Function entry/summary
|
|
* The entry point of a function definition. Signature:
|
|
* function_entry(error, this, cryptoFunctions, txData, blockchainState, stateVariables, inputVariables, blockchainState', stateVariables', inputVariables', outputVariables').
|
|
*
|
|
* 6. Function body
|
|
* Use for any predicate within a function. Signature:
|
|
* function_body(error, this, txData, blockchainState, stateVariables, inputVariables, blockchainState', stateVariables', inputVariables', outputVariables', localVariables).
