Method Detail

getName

public String getName()
Description copied from class: AbstractComplexTerm
get name of term. (i. e. functional symbold)

Specified by:
getName in class AbstractComplexTerm
Returns:
name

getNameIndex

public Object getNameIndex()
Description copied from class: AbstractComplexTerm
get name index in bounded symbol table or sust string, if name in symbol table does not exists.

Specified by:
getNameIndex in class AbstractComplexTerm

getArity

public int getArity()
Description copied from class: AbstractComplexTerm
get arity of term.

Specified by:
getArity in class AbstractComplexTerm
Returns:
arity of term

createSame

public Term createSame(Term[] newBody)
                throws TermWareException
Description copied from class: Term
create term, with same name but new body. If this term have arity 0, or other than original - throws exception.

Specified by:
createSame in class AbstractComplexTerm
Throws:
TermWareException

getSubtermAt

public Term getSubtermAt(int i)
Description copied from class: AbstractComplexTerm
get i-th subterm.

Specified by:
getSubtermAt in class AbstractComplexTerm
Parameters:
i - - index of subterm to get.
Returns:
subterm, which located by index i

setSubtermAt

public void setSubtermAt(int i,
                         Term t)
Description copied from class: AbstractComplexTerm
set i-th subterm.

Specified by:
setSubtermAt in class AbstractComplexTerm
Parameters:
i - - indext of subterm to set.
t - - subterm to set.

recheckEmptyFv

protected void recheckEmptyFv()
recheck existance of propositional variables in subterms.

Overrides:
recheckEmptyFv in class AbstractComplexTerm

termClone

public Term termClone()
               throws TermWareException
Description copied from class: AbstractComplexTerm
do 'deep-clone' of object. i. e. after calling termClone we sure, that call of setSubtermAt() in any subtree of deepClone of original term does not affect original term.

Specified by:
termClone in class AbstractComplexTerm
Throws:
TermWareException

concreteOrder

public PartialOrderingResult concreteOrder(Term x,
                                           Substitution s)
                                    throws TermWareException
Description copied from class: Term
compare for 'more concrete' relation. i. e. x.<(concrete)<(y) means, that for each substitution of free variables sx exists substituion sy : x[sx] = y[sy] .
Substitution s store previously matched variables.

Specified by:
concreteOrder in class Term
Throws:
TermWareException
