Field Summary
boolean	declaredVariableNames If true print the name of the variables as they were declared
boolean	ignoreOps If this option is true each compound term is output in functional notation.
boolean	javaObjects Include JavaObjects in the output
boolean	javaObjectsToString Use .toString() in the output
protected int	numberOfVariables Number of used variables.
boolean	numbervars display terms of form '$VAR'(N) as ('A'+ N%26)+""+(N/26).
OperatorSet	operatorSet Current operator set to use in write term.
boolean	quoted If this option is true, each atom and functor is quoted if it would be necessary for to be input by read_term/3
protected Map<Term,String>	variable2name Map from variables to names.

Field Detail

quoted

public boolean quoted

If this option is true, each atom and functor is quoted if it would be necessary for to be input by read_term/3

---

ignoreOps

public boolean ignoreOps

If this option is true each compound term is output in functional notation. Neither operator notation nor list notation is used when this write option is in force.

---

numbervars

public boolean numbervars

display terms of form '$VAR'(N) as ('A'+ N%26)+""+(N/26). this option requires that ignoreOps = false by ISO Standard checking this condition is left for user.

---

numberOfVariables

protected int numberOfVariables

Number of used variables. This variable is used solely by Term Writer

---

variable2name

protected Map<Term,String> variable2name

Map from variables to names. This variable is used solely by Term Writer.

---

declaredVariableNames

public boolean declaredVariableNames

If true print the name of the variables as they were declared

---

javaObjects

public boolean javaObjects

Include JavaObjects in the output

---

javaObjectsToString

public boolean javaObjectsToString

Use .toString() in the output

---

operatorSet

public OperatorSet operatorSet

Current operator set to use in write term. User need to set this variable if ignore ops is true.

Constructor Detail

public WriteOptions(OperatorSet opset)

Parameters:

opset - the OperatorSet to use for this WriteOptions

---

WriteOptions

public WriteOptions(OperatorSet opset,
 boolean declaredVariableNames,
 boolean numbervars,
 boolean quoted)
