public class SummarizedMethodWithNames
extends SummarizedMethod

A SummarizedMethod (for synthetic functions) with variable names.

Using this class instead of a normal SummarizedMethod enables the use of human-readable variable names in synthetic methods. This should not change th analysis-result but may come in handy when debugging.

Method Details

getLocalVariableName

public String getLocalVariableName(int bcIndex,
 int localNumber)

Returns the variable name to a ssa-number.

Does not respect the value of bcIndex.

Specified by:

getLocalVariableName in interface IMethod

Overrides:

getLocalVariableName in class SummarizedMethod

Returns:

the (source code) name of the local variable of a given number at the specified program counter, or null if the information is not available.

hasLocalVariableTable

public boolean hasLocalVariableTable()

Specified by:

hasLocalVariableTable in interface IMethod

Overrides:

hasLocalVariableTable in class SyntheticMethod

Returns:

true iff the local variable table information for this method is available

makeIR

public IR makeIR(Context context,
 SSAOptions options)

Description copied from class: SyntheticMethod

Most subclasses should override this.

Overrides:

makeIR in class SummarizedMethod

Parameters:

context - TODO

options - options governing IR conversion
