public class CallinInstr
extends CallInstr

Represents any IN HANDLE type of call.

A note about local references vs. xref cross-references: For IN HANDLE, we always use xref rather than local references, even if the handle resolves to THIS-PROCEDURE. Sometimes the handle that resolves to this-procedure might be a var or param, whose possible values could change as a result of changes to other compile units. Xref is designed to propagate changes like that, local references are not. So, we always use xref for IN HANDLE. For simple consistency, we use xref instead of local references even when THIS-PROCEDURE is hard-coded.

Method Detail

calcValueSets2

protected void calcValueSets2()
                       throws java.sql.SQLException,
                              java.io.IOException

This is wrapped by AbstractCall.calcValueSets(). The super's calcValueSets deals with changes to values. This method does the actual value set calculations.

Overrides:

calcValueSets2 in class CallInstr

Throws:

java.sql.SQLException

java.io.IOException

getHandleRVal

public int getHandleRVal()
                  throws java.sql.SQLException,
                         java.io.IOException

Throws:

java.sql.SQLException

java.io.IOException

getOpcode

public Opcode getOpcode()

Overrides:

getOpcode in class CallInstr

getTargetCuids

public java.util.HashSet<java.lang.Integer> getTargetCuids()
                                                    throws java.sql.SQLException,
                                                           java.io.IOException

Throws:

java.sql.SQLException

java.io.IOException

setHandleRVal

public void setHandleRVal(int handleRVal)

setValuesFromByteStream

protected void setValuesFromByteStream(java.io.DataInputStream in)
                                throws java.io.IOException

Overrides:

setValuesFromByteStream in class CallInstr

Throws:

java.io.IOException

toStringFromComments

public java.lang.String toStringFromComments(InstructionSet instrs)
                                      throws java.sql.SQLException

Description copied from class: Bytecode

All Bytecode instruction subclasses should override this eventually.

Overrides:

toStringFromComments in class CallInstr

Returns:

"" if not overridden.

Throws:

java.sql.SQLException

toStringFromData

public java.lang.String toStringFromData()

Appends handleRVal to string values from the basic CallInstr.

Overrides:

toStringFromData in class CallInstr

Returns:

"" if not overridden.

writeValuesToByteStream

protected void writeValuesToByteStream(java.io.DataOutputStream out)
                                throws java.io.IOException

Overrides:

writeValuesToByteStream in class CallInstr

Throws:

java.io.IOException
