public class LocalVariableTypeTable
extends LocalTable

Code blocks compiled from source have local variable type tables mapping generics-using locals used in opcodes to their names and signatures.

Method Summary

void	acceptVisit(BCVisitor visit) Accept a visit from a BCVisitor, calling the appropriate methods to notify the visitor that it has entered this entity, and to provide it with the proper callbacks for each sub-entity owned by this one.
LocalVariableType	addLocalVariableType() Add a local to this table.
LocalVariableType	addLocalVariableType(LocalVariableType local) Import a local from another method/class.
LocalVariableType	addLocalVariableType(String name, String type) Add a local to this table.
LocalVariableType	getLocalVariableType(int local) Return the local with the given locals index, or null if none.
LocalVariableType	getLocalVariableType(String name) Return the local with the given name, or null if none.
LocalVariableType[]	getLocalVariableTypes() Return all the locals of this method.
LocalVariableType[]	getLocalVariableTypes(String name) Return all locals with the given name, or empty array if none.
protected Local	newLocal() Create a new element of this table.
protected Local[]	newLocalArray(int size) Create a new array.

Method Detail

getLocalVariableTypes

public LocalVariableType[] getLocalVariableTypes()

Return all the locals of this method.

getLocalVariableType

public LocalVariableType getLocalVariableType(int local)

Return the local with the given locals index, or null if none.

getLocalVariableType

public LocalVariableType getLocalVariableType(String name)

Return the local with the given name, or null if none. If multiple locals have the given name, which is returned is undefined.

getLocalVariableTypes

public LocalVariableType[] getLocalVariableTypes(String name)

Return all locals with the given name, or empty array if none.

addLocalVariableType

public LocalVariableType addLocalVariableType(LocalVariableType local)

Import a local from another method/class. Note that the program counter and length from the given local is copied directly, and thus will be incorrect unless this method is the same as the one the local is copied from, or the pc and length are reset.

addLocalVariableType

public LocalVariableType addLocalVariableType()

Add a local to this table.

addLocalVariableType

public LocalVariableType addLocalVariableType(String name,
                                              String type)

Add a local to this table.

acceptVisit

public void acceptVisit(BCVisitor visit)

Description copied from interface: VisitAcceptor

Accept a visit from a BCVisitor, calling the appropriate methods to notify the visitor that it has entered this entity, and to provide it with the proper callbacks for each sub-entity owned by this one.

newLocal

protected Local newLocal()

Description copied from class: LocalTable

Create a new element of this table.

Specified by:

Description copied from class: LocalTable

Create a new array.

Specified by:
