Constructor Detail

TupleTerm

public TupleTerm(Expression[] base)
construct tuple term of base terms

Parameters:
base - the array of base terms, base.length > 1
Method Detail

getBase

public Expression[] getBase()
get base expressions

Returns:
the base expression sequence

printCore

public void printCore(java.io.PrintWriter out)
Prints text representation on out (without new line termination).

Specified by:
printCore in interface AST
Specified by:
printCore in class ASTBase
Parameters:
out - the stream on which the text is written

print

public void print(java.io.PrintWriter out)
Prints text representation on out (without new line termination). Overrides ASTBase.print such that parentheses are never printed around the tuple.

Specified by:
print in interface AST
Overrides:
print in class ASTBase
Parameters:
out - the stream on which the text is written

instantiate

public Expression instantiate()
return copy of AST with value references instantiated by the substitutions set in the corresponding declaration identifiers

Returns:
the instantiated copy
