Method Detail

fromString

public static BinaryOperator fromString(java.lang.String s)

Returns a binary operator that matches the specified string s.

Parameters:

s - the string to be matched.

Returns:

the matching operator or null if not found.

print

public void print(java.io.PrintWriter o)

Description copied from interface: Printable

Print the code for the IR represented by the object. Always calls object_print_method(this, o). If the object's print method is null, nothing is printed; this provides an easy mechanism to temporarily hide something.

Specified by:

print in interface Printable

Parameters:

o - The writer on which to print the data.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

verify

public void verify()
            throws java.lang.IllegalStateException

Verifies this operator is valid.

Throws:

java.lang.IllegalStateException - if the operator is invalid.

isCompare

public boolean isCompare()

Checks if this operator belongs to binary comparison operator.

isLogical

public boolean isLogical()

Checks if this operator belongs to boolean logic operator.
