Method Details

readMemoryStringSafe

public static byte[] readMemoryStringSafe(IDebuggerUnit unit,
 long address,
 int length)

Temporarily disabled. Same as readMemorySafe(IDebuggerUnit, long, int).

readMemorySafe

public static byte[] readMemorySafe(IDebuggerUnit unit,
 long address,
 int maxlength)

Read exact memory data at specified address. The result length can be different from length if some data is not accessible or does not exist.

Parameters:

unit - debugger

address - base address

maxlength - wanted length (max)

Returns:

null on error, else the memory data buffer, whose size will be in [0, length]

getPotentialDebuggee

public static ICodeUnit getPotentialDebuggee(IDebuggerUnit manager,
 long memoryAddress)

Retrieve the ICodeUnit that may contains the long memory Address.
If there is only one potential debuggee, it is returned. Otherwise, it searches for a potential debuggee which manages long memory address (for example INativeCodeUnit).

isNativeCodeDebugger

public static boolean isNativeCodeDebugger(IDebuggerUnit unit)

Parameters:

unit -

Returns:

valueEquals

public static boolean valueEquals(IDebuggerVariable va,
 IDebuggerVariable vb)

Fast test equality between two variable values. Faster than using IDebuggerVariable.getTypedValue() because it can bypass some data retrieval.

Parameters:

va - first variable

vb - second variable

Returns:

true when variable share the same value
