Description copied from interface: LazyStringList

Returns the element at the specified position in this list as an Object that will either be a String or a ByteString.

Specified by:

getRaw in interface LazyStringList

Parameters:

index - index of the element to return

Returns:

the element at the specified position in this list

size

public int size()

Specified by:

size in interface Collection<String>

Specified by:

size in interface List<String>

Specified by:

size in class AbstractCollection<String>

getByteString

public ByteString getByteString(int index)

Description copied from interface: LazyStringList

Returns the element at the specified position in this list as a ByteString.

Specified by:

getByteString in interface LazyStringList

Parameters:

index - index of the element to return

Returns:

the element at the specified position in this list

add

public void add(ByteString element)

Description copied from interface: LazyStringList

Appends the specified element to the end of this list (optional operation).

Specified by:

add in interface LazyStringList

Parameters:

element - element to be appended to this list

set

public void set(int index,
                ByteString element)

Description copied from interface: LazyStringList

Replaces the element at the specified position in this list with the specified element (optional operation).

Specified by:

set in interface LazyStringList

Parameters:

index - index of the element to replace

element - the element to be stored at the specified position

addAllByteString

public boolean addAllByteString(Collection<? extends ByteString> element)

Description copied from interface: LazyStringList

Appends all elements in the specified ByteString collection to the end of this list.

Specified by:

addAllByteString in interface LazyStringList

Parameters:

element - collection whose elements are to be added to this list

Returns:

true if this list changed as a result of the call

getByteArray

public byte[] getByteArray(int index)

Description copied from interface: LazyStringList

Returns the element at the specified position in this list as byte[].

Specified by:

getByteArray in interface LazyStringList

Parameters:

index - index of the element to return

Returns:

the element at the specified position in this list

add

public void add(byte[] element)

Description copied from interface: LazyStringList

Appends the specified element to the end of this list (optional operation).

Specified by:

add in interface LazyStringList

Parameters:

element - element to be appended to this list

set

public void set(int index,
                byte[] element)

Description copied from interface: LazyStringList

Replaces the element at the specified position in this list with the specified element (optional operation).

Specified by:

set in interface LazyStringList

Parameters:

index - index of the element to replace

element - the element to be stored at the specified position

addAllByteArray

public boolean addAllByteArray(Collection<byte[]> element)

Description copied from interface: LazyStringList

Appends all elements in the specified byte[] collection to the end of this list.

Specified by:

addAllByteArray in interface LazyStringList

Parameters:

element - collection whose elements are to be added to this list

Returns:

true if this list changed as a result of the call

listIterator

public ListIterator<String> listIterator(int index)

Specified by:

listIterator in interface List<String>

Overrides:

listIterator in class AbstractList<String>

iterator

public Iterator<String> iterator()

Specified by:

iterator in interface Iterable<String>

Specified by:

iterator in interface Collection<String>

Specified by:

iterator in interface List<String>

Overrides:

iterator in class AbstractList<String>

getUnderlyingElements

public List<?> getUnderlyingElements()

Description copied from interface: LazyStringList

Returns an unmodifiable List of the underlying elements, each of which is either a String or its equivalent UTF-8 encoded ByteString or byte[]. It is an error for the caller to modify the returned List, and attempting to do so will result in an UnsupportedOperationException.

Specified by:

getUnderlyingElements in interface LazyStringList

mergeFrom

public void mergeFrom(LazyStringList other)

Description copied from interface: LazyStringList

Merges all elements from another LazyStringList into this one. This method differs from List.addAll(Collection) on that underlying byte arrays are copied instead of reference shared. Immutable API doesn't need to use this method as byte[] is not used there at all.

Specified by:

mergeFrom in interface LazyStringList

asByteArrayList

public List<byte[]> asByteArrayList()

Description copied from interface: LazyStringList

Returns a mutable view of this list. Changes to the view will be made into the original list. This method is used in mutable API only.

Specified by:

asByteArrayList in interface LazyStringList

asByteStringList

public List<ByteString> asByteStringList()

Description copied from interface: ProtocolStringList

Returns a view of the data as a list of ByteStrings.

Specified by:

asByteStringList in interface ProtocolStringList

getUnmodifiableView

public LazyStringList getUnmodifiableView()

Description copied from interface: LazyStringList

Returns an unmodifiable view of the list.

Specified by:

getUnmodifiableView in interface LazyStringList
