Constructor Detail

Logical

public Logical(boolean value)

construct logical constant with denoted value

Parameters:

value - the logical value

Method Detail

getPriority

public int getPriority()

get binding level for printing (lower numbers mean greater binding power)

Specified by:

getPriority in interface Expression

Specified by:

getPriority in class ExpressionBase

Returns:

the priority level

getValue

public boolean getValue()

get value of constant

Returns:

the value.

printCore

public void printCore(java.io.PrintWriter out)

Prints text representation of tree 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 constant.

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

accept

public AST accept(ASTVisitor visitor)

Accept visitor for a visit.

Parameters:

visitor - the visitor who is accepted by this node.

Returns:

the result of the visit (may be null)
