Method Detail

addLocalAddSuperSite

public void addLocalAddSuperSite(int siteAddress)
                          throws java.sql.SQLException,
                                 java.io.IOException

Called by the codegenerator at every addsuper in this CU.

Throws:

java.sql.SQLException

java.io.IOException

beforeWrite

public void beforeWrite(boolean isNewBuild)
                 throws java.sql.SQLException,
                        java.io.IOException

Description copied from class: Bytecode

Called when a build or checkval is done processing a CU, before writing the new/changed records. This base class implementation is a no-op.

Overrides:

beforeWrite in class Bytecode

Throws:

java.sql.SQLException

java.io.IOException

calcValueSets

public void calcValueSets()
                   throws java.sql.SQLException,
                          java.io.IOException

Description copied from class: Bytecode

Calculate the value sets for the instruction.

Called during build, build-recalc, checkvals, and checkvals-recalc. Implementations should only build from external values once. Calculates which xref records are needed as well.

IMPORTANT: Should only ever be called for instructions belonging to an InstructionSet.

Specified by:

calcValueSets in class Bytecode

Throws:

java.sql.SQLException

java.io.IOException

generateProcname2localSuperSet

public java.util.HashMap<java.lang.Integer,java.util.HashSet<int[]>> generateProcname2localSuperSet()
                                                                                             throws java.sql.SQLException,
                                                                                                    java.io.IOException

Generate a map of procnameIDs to super procedure addresses.

Returns:

A map of procnameID to procedure addresses of the form int[]{cuid,procAddress}. The return may be empty but it is never null.

Throws:

java.sql.SQLException

java.io.IOException

getOpcode

public Opcode getOpcode()

Specified by:

getOpcode in class Bytecode

getSelfAndSearchTargetSupers

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

If RUN SUPER or SUPER() is called from this procedure, then we need a set of all possible target super CUs.

The set of possible target CUs is the union of this unit's superCUValues, as well as the superCUValues of all of the CUs in this unit's searchTargetValues.

Super procedure chain searching is not recursive (supers of supers are not added to the set).

The return set is guaranteed not to include this unit's CUID.

Throws:

java.sql.SQLException

java.io.IOException

getSuperCUValues

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

Throws:

java.sql.SQLException

java.io.IOException

getSearchTargetValues

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

Get the SEARCH-TARGET CUIDs.

Throws:

java.sql.SQLException

java.io.IOException

hasSuperCUValue

public boolean hasSuperCUValue(int superCuid)
                        throws java.sql.SQLException,
                               java.io.IOException

Is the input CUID already in this CU's superCUValues set?

Throws:

java.sql.SQLException

java.io.IOException

setValuesFromByteStream

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

Specified by:

setValuesFromByteStream in class Bytecode

Throws:

java.io.IOException

toStringFromData

public java.lang.String toStringFromData()

Description copied from class: Bytecode

All Bytecode instruction subclasses should override this eventually.

Overrides:
