Constructor Detail

ComplexTerm

protected ComplexTerm(Name name,
                      Term[] body,
                      boolean newEmptyFv)

Method Detail

getName

public final String getName()

name for f(x1..xN) is f.

Specified by:

getName in class AbstractComplexTerm

Returns:

name

See Also:

Term.getName()

getNameIndex

public final 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 final int getArity()

Description copied from class: AbstractComplexTerm

get arity of term.

Specified by:

getArity in class AbstractComplexTerm

Returns:

arity of term

getSubtermAt

public final 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.

createSame

public Term createSame(Term[] newBody)

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

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
