Method Detail

cursor

public final int cursor()

Description copied from interface: CodeCursor

Gets the cursor. The cursor is the offset in code units from the start of the input of the next code unit to be read or written, where the input generally consists of the code for a single method.

Specified by:

cursor in interface CodeCursor

baseAddressForCursor

public final int baseAddressForCursor()

Description copied from interface: CodeCursor

Gets the base address associated with the current cursor. This differs from the cursor value when explicitly set (by {@link #setBaseAddress). This is used, in particular, to convey base addresses to switch data payload instructions, whose relative addresses are relative to the address of a dependant switch instruction.

Specified by:

baseAddressForCursor in interface CodeCursor

setBaseAddress

public final void setBaseAddress(int targetAddress,
                  int baseAddress)

Description copied from interface: CodeCursor

Sets the base address for the given target address to be as indicated.

Specified by:

setBaseAddress in interface CodeCursor
