Constructor Detail

CompileunitInstr

public CompileunitInstr()

CompileunitInstr

public CompileunitInstr(int cuid)

The application should use this constructor. The address for a compileunit instruction is set by com.joanju.cg.core.Layout.

CompileunitInstr

public CompileunitInstr(int cuid,
                        int address)

This gets called when extracting bytecodes from the DB.

Method Detail

addActiveNewProcID

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

Returns:

The address for this newly added procedure.

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

                 throws java.sql.SQLException,
                        java.io.IOException

Copy obj's ProcIDs into this object. Checks for null class cast.

Throws:

java.sql.SQLException

java.io.IOException

getActiveProcIds

public java.util.ArrayList<java.lang.Integer> getActiveProcIds()
                                                        throws java.sql.SQLException,
