---

createTableSwitch

private void createTableSwitch(byte[] entries,

                        throws java.io.IOException

For 'tableswitch' opcode this fills the data structure - JSwitchTable.

---

createLookupSwitch

private void createLookupSwitch(byte[] entries,
                                int offset,
                                java.util.Map gotos)
                         throws java.io.IOException

For 'lookupswitch' opcode this fills the data structure - JSwitchTable.

---

getCases

public java.util.List getCases()

---

disassemble

public java.lang.String disassemble()

---

setTypeValue

public void setTypeValue(java.lang.String rhsType,
                         java.lang.String rhsValue)

---

processData

public void processData(java.util.Map gotos)

Process the bytecode stream of case values and targets to individual case blocks.

---

getBranchEntry

public JBranchEntry getBranchEntry()

---

addCaseEntry

public void addCaseEntry(JCaseEntry caseEntry)

Inserts a CaseEntry in the list.

---

toString

public java.lang.String toString()

Description copied from class: java.lang.Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).
