Method Detail

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

getDefglobalAddr

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

Throws:

java.sql.SQLException

java.io.IOException

getContributedValues

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

These are the values that are contributed to the shared var.

Throws:

java.sql.SQLException

java.io.IOException

getSources

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

Description copied from class: Bytecode

Returns null. May be overridden by subclasses.

Overrides:

getSources in class Bytecode

Throws:

java.sql.SQLException

java.io.IOException

getValues

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

Get the global values as well as the locally contributed ones. Most of the times when this is called, the locally contributed values will already be included in the global values.

Overrides:

getValues in class Bytecode

Throws:

java.sql.SQLException

java.io.IOException

getWhereUsed

public java.util.HashSet<java.lang.Integer> getWhereUsed()
                                                  throws java.sql.SQLException,
