Method Summary

boolean	eq(Term x)
boolean	getBoolean() get boolean value, if this term represent boolean, otherwise throw UnsupportedOperationException
static BooleanTerm	getBooleanTerm(boolean b)
String	getName() return string representation
Number	getNumber() get number value, if one exists.
int	getPrimaryType0() return code of level-0 primary type
boolean	isBoolean() is this term is boolean ?
boolean	isNumber() is this term is number ?
void	print(PrintWriter out) print term to out.
Term	termClone() since boolean is immutable, return this.
int	termCompare(Term t) compare functions.

Method Detail

getBooleanTerm

public static BooleanTerm getBooleanTerm(boolean b)

getPrimaryType0

public final int getPrimaryType0()

Description copied from class: Term

return code of level-0 primary type

Specified by:

getPrimaryType0 in class Term

Returns:

code of primary type

PrimaryTypes

isBoolean

public final boolean isBoolean()

is this term is boolean ?

Overrides:

isBoolean in class AbstractPrimitiveTerm

Returns:

true

getBoolean

public final boolean getBoolean()

Description copied from class: Term

get boolean value, if this term represent boolean, otherwise throw UnsupportedOperationException

Overrides:

getBoolean in class AbstractPrimitiveTerm

Returns:

boolean value

isNumber

public final boolean isNumber()

is this term is number ?

Specified by:

isNumber in class Term

Returns:

false

getNumber

public final Number getNumber()

get number value, if one exists. In our case - throw UnsupportedOperationException

Specified by:

getNumber in class Term

Returns:

number value

getName

public String getName()

return string representation

Specified by:

getName in class AbstractPrimitiveTerm

Returns:

name

eq

public final boolean eq(Term x)

Specified by:

eq in class AbstractPrimitiveTerm

termCompare

public final int termCompare(Term t)

Description copied from class: Term

compare functions. define ordering on set of terms. Note, that ordering is not the same as Java build-in compare.

Specified by:

termCompare in class AbstractPrimitiveTerm

Parameters:

t - - term to compare

termClone

public final Term termClone()

since boolean is immutable, return this.

Specified by:

termClone in class AbstractPrimitiveTerm

print

public final void print(PrintWriter out)

Description copied from class: AbstractPrimitiveTerm

print term to out. does not expect recursion.

Specified by:

print in class AbstractPrimitiveTerm

Parameters:

out - - PrintWriter, where to print term.
