Constructor Detail

SChar

public SChar(char c)
Creates a Scheme character from c.

Method Detail

eq_p

public boolean eq_p(SExpr sexpr)
Description copied from class: SExpr
Returns true iff this is equal to sexpr in the eq? sense.

Specified by:
eq_p in class SExpr

eqv_p

public boolean eqv_p(SExpr sexpr)
Description copied from class: SExpr
Returns true iff this is equal to sexpr in the eqv? sense.

Specified by:
eqv_p in class SExpr

equal_p

public boolean equal_p(SExpr sexpr)
Description copied from class: SExpr
Returns true iff this is equal to sexpr in the equal? sense.

Specified by:
equal_p in class SExpr

equals

public boolean equals(java.lang.Object obj)
Description copied from class: SExpr
Returns true iff this is equal to obj. Normally this returns the same result as SExpr.equal_p(org.rubato.scheme.SExpr).

Specified by:
equals in class SExpr

toString

public java.lang.String toString()
Description copied from class: SExpr
Returns a string representation of this SExpr.

Specified by:
toString in class SExpr

display

public java.lang.String display()
Description copied from class: SExpr
Returns a string representation of this SExpr. This is the representation intended to show the result of an evaluation, and should be a valid Scheme expression if possible.

Specified by:
display in class SExpr

isChar

public boolean isChar()
Description copied from class: SExpr
Returns true iff this is a character.

Overrides:
isChar in class SExpr

getChar

public char getChar()
Returns the character in this Scheme value.
