Method Detail

getCpClass

public final CpClass getCpClass()

getNameAndType

public final CpNameAndType getNameAndType()

getStackSize

public int getStackSize()

Return the amount of stack size in words needed to process this field or method, eg If its a field, this returns 2 if its a long or double, otherwise 1.

If its a method this is the sum of the arg sizes.

getNonStaticStackSize

public int getNonStaticStackSize()

Get the number of stack parameters specified by the signature.

The same as the number of arguments, plus 1 for the "this" reference, plus 1 for each long/double argument.

This is needed to produce the argument count for INVOKEINTERFACE methods, which stupidly need that number.

computeHash

public void computeHash()

Description copied from class: CpEntry

Signal the entry to recompute (and store) its hashcode.

The default does nothing.

Overrides:

computeHash in class CpEntry

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
