Class ScriptValsInstr

java.lang.Object
  com.joanju.cg.bytecode.Bytecode
      com.joanju.cg.bytecode.ScriptValsInstr

public class ScriptValsInstr
extends Bytecode

Procedure names or handle values from a user script.

Because many kinds of expressions and data-driven calls cannot be resolved by Callgraph, user scripts may be used to supplement Callgraph.

These values are never recalculated - the script is only run once for the call at build time.

Field Summary

address, cuid, instrSet, nodeNum, xrefs

Constructor Summary

ScriptValsInstr()

ScriptValsInstr(int cuid, int address)

ScriptValsInstr(int cuid, int address, java.util.Collection<java.lang.String> stringVals)
Create with values.

void	calcValueSets() No-op.
Opcode	getOpcode()
java.util.HashSet<java.lang.Integer>	getValues() Get the set of values for this instruction.
protected void	setValuesFromByteStream(java.io.DataInputStream in)

Constructor Detail

ScriptValsInstr

public ScriptValsInstr()

ScriptValsInstr

public ScriptValsInstr(int cuid,
                       int address)

ScriptValsInstr

public ScriptValsInstr(int cuid,
                       int address,
                       java.util.Collection<java.lang.String> stringVals)
                throws java.sql.SQLException

Create with values. If the collection is non-null, then the string ID for each entry is added to the values for this instruction. If there are any nulls in the collection, then UNRESOLVED_VALUE is added.

Throws:

java.sql.SQLException

Method Detail

calcValueSets

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

No-op.

Specified by:

calcValueSets in class Bytecode

Throws:

java.sql.SQLException

java.io.IOException

getOpcode

public Opcode getOpcode()

Specified by:

getOpcode in class Bytecode

getValues

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

Description copied from class: Bytecode

Get the set of values for this instruction. Should be overridden by most subclasses. This default implementation returns a set containing one Layout.UNRESOLVED_VALUE.

Overrides:

getValues in class Bytecode

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:

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
