java.lang.Object
com.android.dx.dex.code.DalvInsn
com.android.dx.dex.code.ZeroSizeInsn
com.android.dx.dex.code.LocalSnapshot
public final class LocalSnapshot extends ZeroSizeInsn
Pseudo-instruction which is used to hold a snapshot of the state of local variable name mappings that exists immediately after the instance in an instruction array.

  • Constructor Details

    • LocalSnapshot

      public LocalSnapshot(SourcePosition position, RegisterSpecSet locals)
      Constructs an instance. The output address of this instance is initially unknown (-1).
      Parameters:
      position - non-null; source position
      locals - non-null; associated local variable state

  • Method Details

    • withRegisterOffset

      public DalvInsn withRegisterOffset(int delta)
      Returns an instance that is just like this one, except that all register references have been offset by the given delta, and its address is reset.
      Overrides:
      withRegisterOffset in class ZeroSizeInsn
      Parameters:
      delta - the amount to offset register references by
      Returns:
      non-null; an appropriately-constructed instance

    • withRegisters

      public DalvInsn withRegisters(RegisterSpecList registers)
      Returns an instance that is just like this one, except that the register list is replaced by the given one, and its address is reset.
      Specified by:
      withRegisters in class DalvInsn
      Parameters:
      registers - non-null; new register list
      Returns:
      non-null; an appropriately-constructed instance

    • getLocals

      public RegisterSpecSet getLocals()
      Gets the local state associated with this instance.
      Returns:
      non-null; the state

    • argString

      protected String argString()
      Gets the string form for any arguments to this instance. Subclasses must override this.
      Specified by:
      argString in class DalvInsn
      Returns:
      null-ok; the string version of any arguments or null if there are none

    • listingString0

      protected String listingString0(boolean noteIndices)
      Helper for DalvInsn.listingString(java.lang.String, int, boolean), which returns the string form of this instance suitable for inclusion in a human-oriented listing dump, not including the instruction address and without respect for any output formatting. This method should return null if this instance should not appear in a listing.
      Specified by:
      listingString0 in class DalvInsn
      Parameters:
      noteIndices - whether to include an explicit notation of constant pool indices
      Returns:
      null-ok; the listing string

    • withMapper

      public DalvInsn withMapper(RegisterMapper mapper)
      Returns an instance that is just like this one, except that the register list is mapped by using mapper.
      Overrides:
      withMapper in class DalvInsn
      Parameters:
      mapper - non-null; used to map registers
      Returns:
      non-null; an appropriately-constructed instance
