                                          Term x2)
                                   throws TermWareException

Throws:

TermWareException

getName

public String getName()

get name of term.

Specified by:

getName in class AbstractComplexTerm

Returns:

CLASS_PATTERN_STRING

getNameIndex

public Object getNameIndex()

get index of name in termware symbol term.

Specified by:

getNameIndex in class AbstractComplexTerm

Returns:

TermWareSymbols.CLASS_PATTERN_INDEX

getPatternName

public String getPatternName()

Description copied from class: AbstractComplexTerm

get name, for which we can forse unfication.

Overrides:

getPatternName in class AbstractComplexTerm

getPatternNameIndex

public Object getPatternNameIndex()

Description copied from class: AbstractComplexTerm

get index for pattern name.

Overrides:

getPatternNameIndex 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

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)
                  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
