All Known Implementing Classes:

ByteArrayAnnotatedOutput

public interface Output
extends com.android.dex.util.ByteOutput

Interface for a sink for binary output. This is similar to java.util.DataOutput, but no IOExceptions are declared, and multibyte output is defined to be little-endian.

Method Summary

void	alignTo(int alignment) Adds extra bytes if necessary (with value 0) to force alignment of the output cursor as given.
void	assertCursor(int expectedCursor) Asserts that the cursor is the given value.
int	getCursor() Gets the current cursor position.
void	write(byte[] bytes) Writes a byte[] to this instance.
void	write(byte[] bytes, int offset, int length) Writes a portion of a byte[] to this instance.
void	write(ByteArray bytes) Writes a ByteArray to this instance.
void	writeByte(int value) Writes a byte to this instance.
void	writeInt(int value) Writes an int to this instance.
void	writeLong(long value) Writes a long to this instance.
void	writeShort(int value) Writes a short to this instance.
int	writeSleb128(int value) Writes a DWARFv3-style unsigned LEB128 integer.
int	writeUleb128(int value) Writes a DWARFv3-style unsigned LEB128 integer.
void	writeZeroes(int count) Writes the given number of 0 bytes.

Method Detail

getCursor

int getCursor()

Gets the current cursor position. This is the same as the number of bytes written to this instance.

Returns:

>= 0; the cursor position

assertCursor

void assertCursor(int expectedCursor)

Asserts that the cursor is the given value.

Parameters:

expectedCursor - the expected cursor value

Throws:

RuntimeException - thrown if getCursor() != expectedCursor

writeByte

void writeByte(int value)

Writes a byte to this instance.

Specified by:

writeByte in interface com.android.dex.util.ByteOutput

Parameters:

value - the value to write; all but the low 8 bits are ignored

writeShort

void writeShort(int value)

Writes a short to this instance.

Parameters:

value - the value to write; all but the low 16 bits are ignored

writeInt

void writeInt(int value)

Writes an int to this instance.

Parameters:

value - the value to write

writeLong

void writeLong(long value)

Writes a long to this instance.

Parameters:

value - the value to write

writeUleb128

int writeUleb128(int value)

Writes a DWARFv3-style unsigned LEB128 integer. For details, see the "Dalvik Executable Format" document or DWARF v3 section 7.6.

Parameters:

value - value to write, treated as an unsigned value

Returns:

1..5; the number of bytes actually written

writeSleb128

int writeSleb128(int value)

Writes a DWARFv3-style unsigned LEB128 integer. For details, see the "Dalvik Executable Format" document or DWARF v3 section 7.6.

Parameters:

value - value to write

Returns:

1..5; the number of bytes actually written

write

void write(ByteArray bytes)

Writes a ByteArray to this instance.

Parameters:

bytes - non-null; the array to write

write

void write(byte[] bytes,
           int offset,
           int length)

Writes a portion of a byte[] to this instance.

Parameters:

bytes - non-null; the array to write

offset - >= 0; offset into bytes for the first byte to write

length - >= 0; number of bytes to write

write

void write(byte[] bytes)

Writes a byte[] to this instance. This is just a convenient shorthand for write(bytes, 0, bytes.length).

Parameters:

bytes - non-null; the array to write

writeZeroes

void writeZeroes(int count)

Writes the given number of 0 bytes.

Parameters:

count - >= 0; the number of zeroes to write

alignTo

void alignTo(int alignment)

Adds extra bytes if necessary (with value 0) to force alignment of the output cursor as given.

Parameters:

alignment - > 0; the alignment; must be a power of two
