Method Detail

fromString

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

hasSideEffects

public static boolean hasSideEffects(UnaryOperator op)

print

public void print(java.io.OutputStream stream)

Description copied from interface: Printable

Print the code for the IR represented by the object. Always calls object_print_method(this, stream). 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:

stream - The stream 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.
