|
* This file represents the specification for CHC predicate sorts.
|
|
|
|
* Types of predicates:
|
|
|
|
*
|
|
|
|
* 1. Interface
|
|
|
|
* The idle state of a contract. Signature:
|
2020-10-13 16:00:26 +00:00
|
|
|
* interface(this, cryptoFunctions, blockchainState, stateVariables).
|
2020-09-08 14:52:58 +00:00
|
|
|
*
|
|
|
|
* 2. Nondet interface
|
|
|
|
* The nondeterminism behavior of a contract. Signature:
|
2020-09-18 16:55:23 +00:00
|
|
|
* nondet_interface(blockchainState, stateVariables, blockchainState', stateVariables').
|
2020-09-08 14:52:58 +00:00
|
|
|
*
|
2020-11-09 15:37:08 +00:00
|
|
|
* 3. Constructor entry/summary
|
|
|
|
* The summary of a contract's deployment procedure.
|
|
|
|
* Signature:
|
|
|
|
* If the contract has a constructor function, this is the same as the summary of that function. Otherwise:
|
|
|
|
* constructor_summary(error, this, cryptoFunctions, txData, blockchainState, blockchainState', stateVariables, stateVariables').
|

|
|
|
*
|
2020-11-09 15:37:08 +00:00
|
|
|
* 4. Function entry/summary
|
2020-09-08 14:52:58 +00:00
|
|
|
* The entry point of a function definition. Signature:
|
2020-10-13 16:00:26 +00:00
|
|
|
* function_entry(error, this, cryptoFunctions, txData, blockchainState, stateVariables, inputVariables, blockchainState', stateVariables', inputVariables', outputVariables').
|

|
|
|
*
|
2020-11-09 15:37:08 +00:00
|
|
|
* 5. Function body
|
2020-09-08 14:52:58 +00:00
|
|
|
* Use for any predicate within a function. Signature:
|
2020-10-13 16:00:26 +00:00
|
|
|
* function_body(error, this, txData, blockchainState, stateVariables, inputVariables, blockchainState', stateVariables', inputVariables', outputVariables', localVariables).
