Public interface¶
new/1
¶
Makes Variable a stream variable. Initial state will be empty.
Compilation flags:
static
Template:
new(Variable)
Mode and number of proofs:
new(-streamvar)
- one
Exceptions:
Variable is not a variable:
type_error(variable,Variable)
new/2
¶
Makes Variable a stream variable and sets its initial state to Value.
Compilation flags:
static
Template:
new(Variable,Value)
Mode and number of proofs:
new(-streamvar,@nonvar)
- one
Exceptions:
Variable is not a variable:
type_error(variable,Variable)
(<=)/2
¶
Sets the state of the stream variable Variable to Value (initializing the variable if needed).
Compilation flags:
static
Template:
Variable<=Value
Mode and number of proofs:
(?streamvar)<=(@nonvar)
- one
(=>)/2
¶
Unifies Value with the current state of the stream variable Variable.
Compilation flags:
static
Template:
Variable=>Value
Mode and number of proofs:
(+streamvar)=>(?nonvar)
