com.android.dx.dex.code.SwitchData

public final class SwitchData
extends VariableSizeInsn

Pseudo-instruction which holds switch data. The switch data is a map of values to target addresses, and this class writes the data in either a "packed" or "sparse" form.

Constructors

Constructor	Description
SwitchData(SourcePosition position, CodeAddress user, IntList cases, CodeAddress[] targets)	Constructs an instance.

Method Summary

Modifier and Type	Method	Description
protected String	argString()	Gets the string form for any arguments to this instance.
int	codeSize()	Gets the size of this instruction, in 16-bit code units.
boolean	isPacked()	Returns whether or not this instance's data will be output as packed.
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.
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.
void	writeTo(AnnotatedOutput out)	Writes this instance to the given output.

Constructor Details

SwitchData

public SwitchData(SourcePosition position,
 CodeAddress user,
 IntList cases,
 CodeAddress[] targets)

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

Parameters:

position - non-null; source position

user - non-null; address representing the instruction that uses this instance

cases - non-null; sorted list of switch cases (keys)

targets - non-null; corresponding list of code addresses; the branch target for each case

Method Details

codeSize

public int codeSize()

Gets the size of this instruction, in 16-bit code units.

Specified by:

codeSize in class DalvInsn

Returns:

>= 0; the code size of this instruction

writeTo

public void writeTo(AnnotatedOutput out)

Writes this instance to the given output. This method should never annotate the output.

Specified by:

writeTo in class DalvInsn

Parameters:

out - non-null; where to write to

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

isPacked

public boolean isPacked()

Returns whether or not this instance's data will be output as packed.

Returns:

true iff the data is to be packed

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
