                               ExpressionBuilderBase expr)

Append a local variable declaration with initializer expression. This variation takes the actual type as a parameter.

Parameters:

type -

vname -

expr - initializer expression

addLocalVariableDeclaration

public void addLocalVariableDeclaration(String tname,
                               String vname,
                               ExpressionBuilderBase expr)

Append a local variable declaration with initializer expression. This variation takes the type name as a parameter.

Parameters:

tname -

vname -

expr - initializer expression

addIfStatement

public void addIfStatement(ExpressionBuilderBase expr,
                  BlockBuilder ifblock)

Append a simple 'if' statement (no else).

Parameters:

addIfElseStatement

public void addIfElseStatement(ExpressionBuilderBase expr,
                      BlockBuilder ifblock,
                      BlockBuilder elseblock)

Append an 'if-else' statement.

Parameters:
