Method Detail

estimate

public static CodeEstimate estimate(SIRFilter filter)

Creates a new instance of CodeEstimate and passes a filter to it. This will result in calculating the size of code and local variables. The size of code and locals will be saved in a cache.

Parameters:

filter - the filter

Returns:

instance of CodeEstimate with code and locals estimates

estimateCode

public static int estimateCode(SIRFilter filter)

Returns estimated code size. If this has already been calculated look up the value in cache. Otherwise do calculation.

Parameters:

filter - the filter

Returns:

estimated size of code

estimateLocals

public static int estimateLocals(SIRFilter filter)

Returns estimated size of locals. If this has already been calculated look up the value in cache. Otherwise do calculation.

Parameters:

filter - the filter

Returns:

estimated size of locals

getLocalsSize

public int getLocalsSize()

Returns size of locals

Returns:

size of locals

getCodeSize

public int getCodeSize()

Returns size of code

Returns:

size of code
