com.android.dx.dex.code.LocalStart

public final class LocalStart
extends ZeroSizeInsn

Pseudo-instruction which is used to introduce a new local variable. That is, an instance of this class in an instruction stream indicates that starting with the subsequent instruction, the indicated variable is bound.

Method Summary

Modifier and Type	Method and Description
protected java.lang.String	argString() Gets the string form for any arguments to this instance.
RegisterSpec	getLocal() Gets the register spec representing the local variable introduced by this instance.
protected java.lang.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.
static java.lang.String	localString(RegisterSpec spec) Returns the local variable listing string for a single register spec.
DalvInsn	withMapper(RegisterMapper mapper) Returns an instance that is just like this one, except that the register list is mapped by using mapper.
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.
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.

Constructor Detail

LocalStart

public LocalStart(SourcePosition position,
                  RegisterSpec local)

Constructs an instance. The output address of this instance is initially unknown (-1).

Parameters:

position - non-null; source position

local - non-null; register spec representing the local variable introduced by this instance

Method Detail

localString

public static java.lang.String localString(RegisterSpec spec)

Returns the local variable listing string for a single register spec.

Parameters:

spec - non-null; the spec to convert

Returns:

non-null; the string form

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

getLocal

public RegisterSpec getLocal()

Gets the register spec representing the local variable introduced by this instance.

Returns:

non-null; the register spec

argString

protected java.lang.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 java.lang.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
