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

getOpcode

public Opcode getOpcode()

Specified by:

getOpcode in class Bytecode

getLocalCUIDValues

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

Get the set of possible CUIDs for the local handle. If this instruction was on THIS-PROCEDURE, then this cuid is the only entry in the set. This is only to be called after local values for this CU have been calculated. The return set may contain the unresolved value. The return set will never contain zero.

Throws:

java.sql.SQLException

java.io.IOException

getSuperCUIDValues

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

Get the set of possible CUIDs for the super handle. This is only to be called after local values for this CU have been calculated. The return set may contain the unresolved value. The return set will never contain zero or this instructions's CUID.

Throws:

java.sql.SQLException

java.io.IOException

isSearchTarget

public boolean isSearchTarget()
                       throws java.sql.SQLException,
                              java.io.IOException

Was this ADD-SUPER instruction specified with the SEARCH-TARGET flag?

Throws:

java.sql.SQLException

java.io.IOException

setSearchTarget

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

Indicate that this ADD-SUPER instruction was specified with the SEARCH-TARGET flag.

Throws:

java.sql.SQLException

java.io.IOException

setLocalHdlRValAddress

public void setLocalHdlRValAddress(int subHdlRVal)

Set by the codegenerator. Is set to zero for hard-coded THIS-PROCEDURE:ADD-SUPER.

setSuperHdlRValAddress

public void setSuperHdlRValAddress(int supHdlRVal)

setValuesFromByteStream

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

Specified by:

setValuesFromByteStream in class Bytecode

Throws:

java.io.IOException

toStringFromComments

public java.lang.String toStringFromComments(InstructionSet instrs)

Description copied from class: Bytecode

All Bytecode instruction subclasses should override this eventually.

Overrides:

toStringFromComments in class Bytecode

Returns:

"" if not overridden.

toStringFromData

public java.lang.String toStringFromData()

Description copied from class: Bytecode

All Bytecode instruction subclasses should override this eventually.

Overrides:

toStringFromData in class Bytecode

Returns:

"" if not overridden.

writeValuesToByteStream

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

Specified by:

writeValuesToByteStream in class Bytecode

Throws:

java.io.IOException
